Analytical And Empirical Methods For Usability Evaluation Computer Science Essay

Usability Evaluation is evaluation on the capacity of the usability of the interface plan. Two spirithither manages representationd coercion this evaluation prescribe are Heuristic Evaluation (analytical manage) and Representationr Ordealing (tentative manage). Twain of these manages enjoy their hold strengths and limitations, depending on the objectives and the matter of the usability evaluation.

TASK 1: Manages Description

The Heuristics Evaluation

Heuristic evaluation is a usability neglect technique highest patent free by Jakob Nielsen and his colleagues (Sharp, 2007). According to Jakob Nielsen (1994), Heuristic evaluation is a usability engineering manage coercion opinion the usability drifts in a representationr interface plan so that they can be lively to as divorce of an iterative plan prescribe. It is usually influenceed by a weak assemblage of evaluators presented with an interface plan and are requisanguine to evaluate whether each of its divorces follows a regular of typical usability powers or `heuristics’. The neglect of the interface is dseparate by each indivisibleal evaluator. Doggedly, the evaluators emanationion through the interface divers eras, at trivialest twice. The highest plump is to end the arrive-at of the run of the interaction, whilst the promote or past, to aggravatehaul on local diversified disverse divorces of the interface. Integral drifts encountesanguine are chronicled and inventoryed deeperneathneath the relative heuristics. `Barely behind integral evaluations enjoy been completed are the evaluators integralowed to reveal and enjoy their opinions aggregated. This progress is significant in manage to secure dogged and unprejudiced evaluations from each evaluator’ (Jakob Nielsen, 1990). The equitpowerful coercion assemblageing end the evaluators is to discern as sundry drifts as practicable, accordingly separate separate evaluator would referpowerful be powerful to invent integral the drifts. Opposed evaluator conquer discern opposed drifts.

The Heuristic Evaluation (patent free by Jakob Nielsen and Mack (1994) consists of ten (10) unconcealed powers or “a administration of thumb.” They are Vision of prescribe foothold; Match among prescribe and the unconcealed world; Representationr manage and insubservience; Consistency and trutinations; Error interruption; Recognition rather than recall; Flexibility and gainingness of representation; Aesthetic and minimainventory plan; Succor representationrs entireow, diagnose, and cure from errors; and Succor and documentation. However, the evaluator may addition odd heuristic divorce or category-local heuristics to addition the unconcealed heuristics.

Strengths of Heuristic Evaluation:

Tranquility in Organizing Evaluation: It is unconstrained to do it. Entity dogged the evaluators can aggravatehaul anyera as crave as there is emanation to be aggravatehauled. The integral neglect prescribe conquer be handled by the evaluators quenchedface any mediation from anybody, until the decisive divorce of the evaluation assemblage whereby they succeeding simultaneously to sift-canvass anything that has been discerned. Anteriorly the decisive divorce, the evaluators conquer reiterate the neglect divers eras, at trivialest twice.

Hither Absorb: Compasanguine to representationr ordealing evaluation which demands indivisibleal laboratory, heuristics evaluation involves hitherer absorb and era. The calculate of evaluators are very considereffectual hither, from 3 to 5 people, compasanguine to representationr ordealing manage which requires sundry past representationrs divorceicipating to be serviceable. Heuristic neglect can to-boot be influenceed anywhere, equal at the station or diligence ground.

Serviceeffectual Detection of Drifts: By power of their tests and everydayity, it is entirely unconstrained coercion the evaluators to authenticate superior and younger drifts of the interface. The evaluators sift-canvassion assemblage conquer succor identification of drifts that are missed quenched or unremembesanguine by other evaluators.


Separate Evaluator and Drift detection: Heuristic Evaluation can be dseparate by a separate indivisibleal evaluator. However, it is severe coercion separate indiperceptible to discern integral the usability drifts in an interface. According to Nielsen, averaging from aggravate 6 projects , a separate evaluator barely build 35% of the usability drifts of the interface.

Referpowerful Providing Prescribeatic Drift Fixes: `Heuristic evaluation does referpowerful collect a prescribeatic practice to besecure fixes to the usability drifts or a practice to assess the probpowerful capacity of any plan.'(J.Nielsen)

The Paradox of the Hither Absorb: Employing a separate evaluator can diminish absorb. Referablewithstanding the risk is the cloakage of the drifts. Thus, it is sure to adopt `multiple evaluators’ which resources a surpassing absorb.

The Risk of Professional Varyences: If the evaluators are referpowerful divorce of the outgrowth team, they may referpowerful be certified of technical limitations on the plan or why sure plan decisions were made. This may consign to varyences among the outgrowth team and the evaluators, which may defer despatch drifts and chastisement of the usability drifts signed during the usability evaluation.

Capturing of separate-era declining initiative drift: As Heuristic evaluations are divergently citationured, there is a approvely- hood coercion the evaluators to sculmination separate-era declining-initiative drifts which may referpowerful be significant to punish. It conquer be a dissipate of era and absorb if evaluators are pre-occupied with additionressing this peel of drifts, referpowerful barely to the evaluators themselves, referablewithstanding to-boot to the emanation developer.

EMPIRICAL METHOD: Representationr Ordealing

User ordealing is a representationr-centsanguine usability evaluation manage that employs evaluators to behold and annals the exploit of representationr during the ordeal assemblage. According to Helen Sharp who quoted from Dumas and Sanguineish(1999), `the relishlihood is to ordeal whether the emanation entity patent free is uspowerful by the intentional representationr population to end the labors coercion which it was planed.’ Thus, it is a manage of opinion drift areas by concerning the people who are harmonious to the tarend representationrs to transact sure labors. Administesanguine in the representationr ordealing laboratory and in a manageled environment among the scheduled era, the representationrs are requisanguine to transact either sure labors, such as navigating through the menus, referableification profound, lection the opposed typefaces, or other local labors. During the representationr ordealing assemblages, the evaluator `interpretes the representationr’s intermissionraintces in manage to distrust how these intermissionraintces are connected to the usability issues in the plan of the interface'(J. Nielsen, 1994). The evaluators annals anything abquenched what, how and when the representationrs do. The divorceicipants’ position, intermissionraintce, behaviors, facial observe, remarks or other peel of gestures are integral chronicled.


Strengths of Representationr Ordealing

The Strength of Tentative Manage: Authenticateing emanation drifts by observing tentatively the representationrs interforce with the interface conquer imbisect rectify deeperneathstanding of the drifts and demands of the representationrs. It conquer be excite enhanced when followed by the brainstorming assemblage.

The Emanationive Side of Brainstorming: The brainstorming or `think aloud’ assemblages among the evaluators and the representationrs encourages representationrs to colloquy and distribute their tests. This perspicuously succors discerny of sundry past drifts coercion the chastisement or progress of the emanation.

Users Demand Succeeding Highest: Sometimes, evaluators or software outgrowth specialists enjoy their hold biased views of what representationrs nonproduction or demand. Representationr ordeals conquer counterbalance the fix by powerful what is unconcealedly demanded or expected from the representationrs perspectives. Giving initiative to drifts aggravated by the representationrs conquer to-boot hopeful dhold professional varyences among the evaluators and the prescribe developer.


Drift in Determining The Correct Calculate of Representationr Ordealers: The drift is to determine on how sundry representationrs are untrue coercion the ordeal. There are opposed of opinions pertaining to the correct calculates of representationrs to be adoptd in the lab. A elaboration studies influenceed by Virzi(1990) pretence that 80% of drifts uncovesanguine installed on a assemblage of 5, and 90%, from a assemblage of 10 representationrs. Such be the subject, past representationr calculates implies past absorbs. However, in-fact, it is referpowerful unconstrained to determine on the most absorb-serviceeffectual calculates or optimum calculate of representationrs to divorceicipate in the usability ordealing, accordingly conclusions may vary if ordealed in opposed matter , environment and era.

Non-coverage of Dischargealities: Sometimes, the ordeal could referpowerful caggravate integral the dischargealities of the emanation in such occupation era and environment.

Inability to Sculmination Younger Usability Drifts: Though this manage of evaluation is cheerful in discerning superior HCI drifts, it is entirely hard to behold younger usability drifts, such as typographic subtility. There is a possibility that equal the corresponding gesture beholdd from the representationrs can be interpreted opposedly by each indivisibleal evaluator.


Judging from the strengths and weaknesses of twain Heuristic Evaluation and Representationr Ordealing, it is rather hard to deduce which either manage is rectify. It is an `evaluator-centred’ versus `user-centred’ approximationes . Unreally, it is cheerful to enjoy twain manages as twain enjoy their hold advantages and can correlative each other.

Five (5) Usabilty Drifts To the Representationr

Homepage Layout

The Drifts: The measure on the Abodepage was referpowerful opportunely stereotyped. The influence of gross spontaneously alternating photographs correct at the culmination-correct of the page and leaving a gross snowy measure on the left face is a dissipate of constructionsite measure. With such arrival, it makes the excellent divorce of the Abodepage `misaligned’. Free aces such as `Twintech Yemen Branch’ thumbnail and other branches presented in the coercion m of hyperextract in Sabah, Kota Bharu, and Sri Damansara are referpowerful visibly located. Equal `Onverse Collision ‘ weary was referpowerful perceptible when the constructionsite is unconcealed. Surprisingly, the `Onverse Collision’ was referpowerful dischargeing. When it was clicked, it consigns to referablehing, as if it was idle weary!

Usabilty Drifts To the Representationr: Thinly stereotyped measure` may perfectay unpremeditated a representationr. A representationr conquer invent hardy in proroot the requisanguine aces or pages. Icons which are referpowerful perceptible conquer dissipate the representationrs era in proroot coercion the correct page coercion past referableification or frequentedion. Coercion pattern, a representationr has to quest coercion other branches somewhere dhold the pages or has to go to the next page to observe coercion Twintech branches. There is an occurance of thin satisfyend prescribe coercion basic referableification. Coercion pattern, when `onverse collision coercionm’ icon was clicked, there was no satisfy end. Instead of ostentationing the representationr with the supplicateed onverse collision coercionm, there was referablehing pretencen! This can power virtual garden applicants renouncing the fence . Non-functioning Onverse Collision conquer a perfectay unpremeditated subject! The separate equalize Menu sunderially takes a craveer proroot era coercion the representationr. This favor flexibility and tranquility of navigation or manage of the constructionsite resigned. It conquer be past opportune if a representationr can excellent ace measure by making cherisheds at the ocean menu.

“Twintech Yemen Branch” icon is thinly located. It would be past perceptible if it is located at the culmination page of the Abodepage instead of at the proroot of the page. Approvewise, free hyperextract or icons coercion other branches in Malaysia are referpowerful fixd on the Abodepage, instead a representationr has to observe coercion the join coercion other branches in Kota Bharu and Sarawak, Malaysia. They are located deeperneathneath the `Students’ menu!

Notification abquenched the Discussion was very overflowing. On the Abodepage, referableification on discussion were located in three fixs . It would be hither confusing if the corresponding referableification is fixd deeperneathneath separate banner! As such a representationr demands to scroll excite dhold or to go to other pages to quest coercion the branches.

The heuristics referpowerful uniteed:

Aesthetic and Minimainventory Plan: This is accordingly care was referpowerful impartn to the Abodepage layquenched which can imbisect visual impression to the representationr. Basic resigned aces should be visibly stereotyped and attrfree to the representationr. The dissolute ordainment of free onverse Twintech branches and no conclusion Onverse Collision weary conquer sunderially intimiage a representationr to endure browsing. To-boot, the ordainment of gross photographs at the culmination page compose gross snowy measures; and having idle caption-hither thumbnail draws randomly in the pages, plbeneath the enticingness of the constructionsite.

Flexibility and Gainingness of Representation: In bearing to the overhead comments, the thin ordainment of free icons limits gainingness in habiting other pages of the constructionsite.

Consistency and Trutinations: The sundry coercionms of extract, be it appellation, subtitles, paragraphs, captions, or font bignesss delineate subtility and aggravatesight of basic trutinations. Equal, in separate page, a representationr conquer discern declining contrarietying appellation or sub-appellation verses and representation of fail extract that can be mistaken coercion hyperextract discharges.

The Menu and Quest Discharge (Unconcealed Navigation Drifts):

The Drifts: The Menu, correctly located on the excellent left of the Abodepage consists of five (5) menu aces: Abode; Student; Programmes of Studies ; Abquenched Us; and Contact Us. However, the Menu was referpowerful planed to enjoy a `pull down’ portion which could adapt representationr excellention past at-once, distinctly coercion the `Programmes of Studies’, Student, or Abquenched Us.

Usability Drift To The Representationr: If a representationr nonproductions to habit a local Programme, e.g. Biotechnology, a representationr has to go to the Programme page, then from there, a representationr conquer excellent `Biotechnology’ from the inventory. If it is a multiequalize menu, a representationr can largely habit the `Biotechnology’ page by proper separate click! Menu consisting of five (5) ocean aces to-boot favor the expedite of habit to the intermission of the measure. In bearing to this, the menu does referpowerful hold extensive basic measure. Coercion pattern, deeperneathneath `Abquenched Us’ menu, there was no referableification abquenched the garden organizational citationure, though it was typical as a University Garden abquenched 12 years ago! Equal if a representationr clicks `Contact Us’ of the `Abquenched Us’ menu, apt referableification is referpowerful there.

The Heuristic Referpowerful Uniteed:

User Manage and Insubservience: The separate equalize menu delays sprightly performance of a representationr. A representationr has to quest `manually’ to observe coercion perchance, obscure requisanguine referableification.

Flexibility and Tranquility of representation: Relating to the manage drift, the stout portion of the menu plan limits the flexibility of a representationr. Instead of excellenting an ace frequented from the menu, a representationr has to deeperneathgo divers quest prescribe.

Consistency and Trutinations: Menu plan does referpowerful gain a typical trutination of sophistication. Simply, `philosophy of trutination’ should steadfast care to the practice an interface prescribe pleases the representationr.

Non-functioning `Onverse Collision’ Weary and `Search’ Referablewithstandington.

The Drifts: These two drifts are of the corresponding peel. Twain referablewithstandingtons/ pummeles consign to referablehing. The `Onverse Collision’ is fixd on well-behaved-behaved-behaved-behaved page of this constructionsite. However, when a representationr clicks to end the collision coercionm, it does referpowerful ostentation anything. In legitimatety it takes entirely a period abquenched 2 minutes downloading era proper to imbisect `Connection is Era Quenched’ referableice. Divers attempts were made, referablewithstanding endting the corresponding conclusion. Approvewise, the constructionsite `Search’ referablewithstandington to-boot demonstrates the corresponding satisfyback. It did referpowerful discharge as expected. The quest pummel/bar is undignified. There is no satisfyend behind inputting supplicateed referableification, referablewithstanding barely refreshed the page. Coercion pattern, at the Student page, when the signal `biotechnology’ was typed in the Quest pummel , it ostentationed the Abodepage instead of the `Biotechnology’ page! To-boot when clicking free Discussion draw , it does referpowerful import to the discussion referableification page, referablewithstanding to the Abodepage frequently!

Usability Drifts To The Representationr: The non-functioning `Onverse Collision’ conquer perfectay unpremeditated the representationr or virtual garden applicant. Perchance, the representationr may test a scant eras. Referablewithstanding if the satisfyend is `zero’ , the assemblage does referpowerful barely dissipate the representationrs era, referablewithstanding to-boot can consign to afflict. It alsok abquenched 3 minutes to halt coercion the Onverse Collision to end the `era expired’ referableice! The period is considesanguine very crave coercion an interface gainingness trutinations. Regarding the `non-performing’ Quest pummel , it is a absolute dissipate of era to the representationr when the supplicateed referableification was referpowerful collectd. In legitimatety, the Quest conclusion was the ostentation of the Abodepage frequently! The corresponding satisfyend appeasanguine when a `Convocation’ draw icon was clicked, that is, the Abodepage was frequently ostentationed. This peel of satisfyend undoubtedly conquer import abquenched intellectual afflict and frustrations to a representationr . It favors the mildness of the navigation run.

The Heuristics Referpowerful uniteed:

Vision of prescribe foothold: Coercion integral the three free aces, the satisfyend prescribe was very penniless. The Onverse Collision failed to effect the collision page; the Quest pummel to-boot failed to quest the correct referableification referablewithstanding import the Abodepage to the representationr; and the free Discussion to-boot led the representationr to the Abodepage. So, the constructionsite of verse kept the representationr known, referablewithstanding abquenched star else that a representationr was referpowerful assiduous in!

Error interruption: Error interruption watchful was referpowerful flashed or signaled to the representationr, distinctly coercion failing to ostentation the onverse collision coercionm.

Flexibility and gainingness in representation: As these discharges were referpowerful dischargeing as expected, the constructionsite did referpowerful imbisect opening coercion the representationr to browse or search largely and spontaneously to understand past abquenched its measure.

Consistency and Trutinations: From the conclusions achieve , that is, thin satisfyend prescribe, it is free that the constructionsite was referpowerful been aggravatehauled or representationr ordealed satisfactorily. The planing of the construction missed the basic interface trutinations in succoring representationrs to enjoy gladsome tests.

User manage and insubservience: The representationr was referpowerful powerful to test insubservience in tender aplump accordingly the browsing prescribe was hampesanguine by free however non-functioning icon referablewithstandingtons.

Sprightly Debouchureing Drift and Abode

The Drifts: There is no `button’ coercion sprightly page debouchureing. A representationr has to representation the trutination `Abode referablewithstandington’ to debouchure a labor. So, when a representationr nonproductions to debouchure the page at-once, the representationr has to scroll dhold coercion Abode referablewithstandington correct to the proroot of the page, or using the `End Measure’ arrow. There is to-boot no `Home’ hyperextract verse located visibly in the emanationioning area where a representationr does referpowerful enjoy to observe coercion Abode referablewithstandington dhold the page (or using the `Previous -`Next’ page approximation). Equal that, it was piercing accordingly it takes entirely a era. It would be rectify if the Abode or Previous -Next page referablewithstandington are fixd at the free page or at a past perceptible fix or unconstrained to gain on the fence.

Usability drift to The Representationr: Since the `sprightly debouchure’ is referpowerful built in the interface plan, a representationr has to either debouchure by clicking the abode referablewithstandington which is distant dhold the pages or using the `end Arrow’ of the Window excellent Left cavity to debouchure. As an pattern , when `Staff Constructionmail’ is clicked, it prompts an `authentication window’ coercion the representationr to penetrate `User Name’ and `Password’ . If a representationr determine referpowerful to consign on referablewithstanding approve to debouchure the page, a representationr has to representation `Cancel’ referablewithstandington of the window, accordingly there is no sprightly debouchure icon. However, the weight the Cancel referablewithstandington is clicked, it ostentationed another constructionmail window coercion Log In. At this page a representationr canreferpowerful debouchure at-once accordingly there is no Abode referablewithstandington anywhere. A representationr has to click `End Arrow’ on the browser to go end to the Abodepage. The was no `emergency debouchure’ prescribe on this divorceicular page. This is entirely incommode as it takes past steps to debouchure.

The heuristics referpowerful uniteed:

User Manage and Insubservience: Deeperneathneath this heuristic power, there should be an interface discharge coercion “emergency debouchure” to license unwanted sundericularize quenchedface having to go through an exceeding discourse’ (J.Nielsen,1994) . Referablewithstanding in the overhead subject, a representationr has to do scant other steps anteriorly debouchureing by clicking the `End Arrow’ guide.

Consistency and Trutinations: To be in-sync with today’s trutination, a prescribe should succor representationr to debouchure with separate guide clap, instead of going through divers steps.

Flexibility and Gainingness of representation: Behind the neglect transacted, it is self-evident that that interface prescribe planer unremembesanguine the `flexibility and gainingness of representation ‘ heuristic that can adapt twain the prompt and the student representationr.

Extract Capacity: Declining colour contrariety., font bignesss and a amalgamate of excellent subjects and declininger subject in paragraphs or extract.

The Drifts: In unconcealed, the colour contrariety of the extract adaptation may afflict a representationr. The cherished of also declining obscure of grey representationd coercion age verses, some sub-titles, and some weak paragraphs purifys the eyes of a representationr. In contrariety, the representation of sky sky sky cerulean `Contact Us’ pummel occupying approximately the integral fence can astonish a representationr. Some smudgy lore of the additionress are referpowerful interpretable.

Usability drift To The Representationr: The declining colour contrariety simultaneously with weak font tends to purify the eyes of the representationrs eyes. As typically testd, fail extract verses usually denote hypertext, referablewithstanding in this construction, they are referable. This may confrepresentation a representationr and can consign to loss and afflict. As it is referpowerful visally free attributable to its weak fonts and fail grey verses, it is entirely laborious to a representationr. A representationr has to disburse era focusing on the extract to interpret it. Equal the grey obscures of colour contrariety as well-behaved-behaved-behaved-behaved as the font bigness contrariety among the appellations and sub-titles are referpowerful succoring the representationr to test the verses or paragraphs freely and opportunely. Excite past on the Faculty pages, there are a amalgamate of sanguine and ebon colour paragraphs. In contrariety, the `Contact Us’ page ostentations a very adventurous sizpowerful fonts that is entirely blistering visual. With sky sky sky cerulean endgplump and ebon smudgy adaptations, a representationr who is referpowerful everyday with the vernacular conquer invent hardy in lection and deeperneathstanding the referableice or the signals.

The heuristic referpowerful uniteed:

Consistency and Trutinations: Using also declining fail grey colour extract does referpowerful conshape to the power of contrariety coercion serviceableness in consigning a referableice. There is subtility in the cherished of colours and obscures of colours representationd to consign sure measure of the constructionsite.

Aesthetic and minimainventory plan: The ostentation of extract visual with amalgamateed of colours and fonts diminish the aesthetic side of this constructionsite. It can be an `eye sore’ if a representationr stays crave on the construction.


Installed on the Heuristic Evaluation influenceed, drifts that enjoy been discerned oceanly pertains to the Visiblity of prescribe foothold, Representationr manage and insubservience, Consistency and trutinations, Flexibility and gainingness of representation, and Aesthetic and minimainventory plan. The heuristic neglect influenceed could referpowerful end satisfybacks on other heuristics, namely, Match among prescribe and the unconcealed world; Error interruption; Recognition rather than recall; Succor representationrs entireow, diagnose, and cure from errors; and Succor and documentation. Perchance, this is attributable to the regularity of the construction which is planed to imbisect garden referableification rather than a past interfree interface prescribe. Separate side to be highlighted is the `Onverse Collision Pummel’. As the `Onverse Collision’ page canreferpowerful be habited, it is hard to aggravatehaul whether the prescribe has Error Interruption prescribe or referable. So distant, there was no `Error’ watchful build.

Basic or superior drifts that should be rectified by the IUCTT are the Satisfyend prescribe, Abodepage layquenched , Menu capacity, Abode referablewithstandington, Sprightly Debouchure referablewithstandington, and the integral extract capacity. The non-functioning `onverse collision weary’ conquer perfectay unpremeditated virtual applicants. Approvewise, the want of the `search’ referablewithstandington to purpose a representationr’s supplicate can conclusion in representationr frustration. The satisfyend ostentation of the Abodepage instead of the expected page or additionress whenever a representationr clicks `Interpret Past’ or other `Twintech branches’ is very blistering. The relishlihood and the layquenched of the Abodepage as well-behaved-behaved-behaved-behaved as the poor menu discharges may favor the interface gainingness and the serviceableness. The layquenched of the Abodepage fence and other pages are referpowerful visually enticing. There are sundry snowy measures twain in the abodepage and other pages. Regarding the Menu, there is no pop-up or pull-dhold menu. Thus, the Menu discharges could be excite improved to adapt navigation of constructionsite measure. To be in-sync with today’s trutination, tt should be `upgraded’ from separate equalize to multiequalize as well-behaved-behaved-behaved-behaved as incrtranquility the menu aces from five(5) to sequal (7) aces or past wherever apt. The `Contact Us’ page observes blistering attributable to the `smudgy’ ebon adventurous font. Coercion important flexibility and tranquility of interface interaction, the prescribe should strengthen unconstrained habit Abode and Sprightly Debouchure referablewithstandington to incrtranquility the gainingness and the serviceableness of navigation. The extract coercion the integral constructionsite should be improved in expression of colour contrariety, font bignesss coercion the extract appellations, subtitles, ages, hypertext, communication subjects ( the cherished of declininger and excellent subjects)and the approve. Judging from the extract in the constructiondsite, it can be distrustsanguine that this divorce has referpowerful been impartn care. The extract divorce of this constructionsite demands to be improved vestibule the aesthetic sides into importance. Other younger drifts to be additionressed are the non-functional idle thumbnail-approve draws, ordainment of free thumbnail draws coercion past vision and the layquenched of integral the constructionsite pages. Coercion excite progress, this constructionsite should be re-inspected heuristically or by representationr ordealing manage coercion the inteintermission of the representationrs.
