Everything Student Life

Overview of Application

Aimed Primarily at studentsHowever there are two types of users;

The Buyer (Students), The Seller (Landlords/Event Planners.. Etc.)Students can also act as a multiuser!

Designed as an iPhone ‘App’; Student accessibility (Based on requirements gathering)

My users

Two users;•Buyer (Student)•Seller (Landlord)

•1st Use Case shows the buyer browse for accommodation(To rent, in south Dublin, for less than 1500 a month)

•2nd Use Case explores the app from the seller, uploading ad,advertising accommodation

Persona

Use Case 1 – Buyer (Student)

This is Dave. Dave is twenty and entering his Second year in Trinity College Dublin. Dave is from Co. Meath.Dave lived in Trinity Halls during his first year of College, where he made lots of new friends.Dave is now looking for accommodation, with a fewFriends he made in Trinity Halls, but finding It tricky to find something suited to his needs,Within his price range, and for a lease that only lastsThe academic year.

Dave knows once he finds a place he will need to Fork out for some furniture to furnish his knew place And make it feel more like home.

Dave also has lots of expensive books that he no Longer needs this year.

Persona

Use Case 2 – Seller (Landlord)

This is Jane. Jane was a stay at home mom to three.Jane’s three children are all grown up now.Jane lives in Cork, but bought a property in DublinSo when her children were attending college they hadSomewhere to stay.Two of Jane’s children still live in Dublin with their Spouses and kids, while her other child emigrated toAustralia.Jane doesn’t want to sell the property as she still usesIt once and again, mainly during summer to visit her Children and grand children.

Jane has decided it is in a prime location for college Students and it suits her to rent it during the Academic year.

Methodology

I used a user centred design approach when designing my application.

What is user centred design?Why use this and not another?

What is User Centred Design?

User Centred design is a user interface design process in which the needs and wants of the end user are given extensive attention.

Multi stage problem solving process. The difference from other product design is that

user-centred design tries to optimize the product around how users can, want, or need to use the product, rather than forcing the users to change their behaviour to accommodate the product (Bryce, 1996).

But Why User Centred Design?User Centred Design is a well established

process that is used by many organisations to deliver products that meet users expectations (Sugar, 2001).

Ensures that the software is usable to novice users as well as advanced users.Prevents loss of money, due to insurance of use (Cooper, Reimann & Cronin, 2008)

Requirements Gathering

I used an online questionnaire for my initial requirements gathering

i.e., “How would you like to access the programme?”

Via website, Smartphone or android app?? Studentaccommodationavailabilities

Buy and Sellcollege books

Other = Student events and student deals

Requirements Gathering

• What criteria you are looking for?• Just dedicated to your college/ all colleges? • Just Dublin?

“What type of housing would you be looking for”?

Interface Design

How I applied interface design rules to my prototype: Nielsen’s Heuristics Nielsen’s Heuristics (They are called "heuristics"

because they are more in the nature of rules of thumb than specific usability guidelines).

Pressman's Principles Pressman's Principles (An agile yet disciplined framework for building web applications).

Other Mobile Design PrinciplesOther Mobile Design Principles

Nielsen’s Heuristics(Examples)

Help users recognize,diagnose, and recoverfrom errors

Error messages should be expressed in plain language, precisely indicate the problem, and constructively suggest a solution.

Nielsen’s Heuristics(Examples)

User control and freedom

Users often choose system functions by mistake and will need a clearly marked "emergency exit" to leave the unwanted state without having to go through an extended dialogue.

Pressman's Principles(examples)

Navigability

o The user should be able to understand how to move about the WebApp without having to search for navigational links.

Pressman's Principles(examples)

Anticipation

o The user should be able to anticipate his or her next move

Theresa Neil(Example)

Visibility of system status

(Feedback)

The system should always keep users informed about what is going on, through appropriate feedback within reasonable time.
