The aim of the exercise work is develop a micro-blogging website, similar to Twitter. As an example
of the kind of requirements we need, users of the site should be able to:
• create an account and login to a home page
• post status updates from their home page, including tags (similar to Twitter's hash tags)
• receive updates of other people's status posts on their home page in a newsfeed
• subscribe to follow posts that contain a particular tag (for example, you could say that you want to receive all status posts that contain the tag #occupy wall street)
• follow certain users and receive their updates.
In the first exercise work, we need to work out the requirements in more detail. You should submit a report that describes the following points:
• a full description of the requirements, describing in detail how users will interact with the site – you can include examples and illustrations to help with your explanations
• data requirements:
 what data will need to be communicated between browser and server and in what format and with what structure? (You can think about whether you need XML/JSON/etc.) Your discussion should include examples (on paper) of data transfer between browser client and web server.
 will the data need to be stored on the server in a database? If so, what tables will you need? How will the database be used to provide data to users' home pages.
 communication requirements - how will the browser and server communicate. You will need to think about how the server will push updates to the browser and how it will know what updates to push. What does the server need to know in order to send the right data.
 site design - what screens will the user see when they interact with the site (these can be mock-up's for the time being, but will need to be properly developed for the second exercise work) and how will they navigate between the different screens.
Try to keep the number of pages to less than 15. Try to make good use of illustrations and examples.
Marking scheme :
• 20% for a good breakdown of the requirements and discussion of users' interaction
• 30% for data requirements (20% for data exchange formats, 10% for database discussion)
• 20% for discussion of communication requirements
• 20% for site design discussion (10% screen design, 10% navigation)
• 10% for quality of presentation (5% quality of writing, 5% for meeting submission requirements)
• A good submission will include a full set of requirements (nothing missing), a good understanding of what data needs to be communicated between server and client,
• together with data formats that make it easy to support the functionality of the site,
• a good understanding of what database support is required,
• followed by a full set of screen designs together with a supporting navigational scheme in the form of a sitemap.
• It would also feature a good standard of writing - good expression, no grammatical or spelling mistakes,
• good presentation - with well-chosen examples and illustrations.
You are asked to produce a partial design for a GPS assisted mobile tourist
application. It is anticipated that the application will run on GPS, GPRS, and
3G enabled PDA device.
The application shall allow a tourist to freely roam the central London area
and request location-based information. The location of the user shall be
discovered by the system by use of GPS hardware. Information such as
maps, audio guides (and images) of attractions and historical sites shall be
made available on request to the user. In addition, local business information
on services such as restaurants (menus, prices etc.), bars, and shops shall
also be made available on demand. In addition, businesses can push
messages to the user when they are near certain locations. For example, this
might be a special offer from a local restaurant with discount meals or an offer
of tickets to a local attraction.
Business can register via a website to offer services and load their push
messages to update offers and other details whenever they wish.
• User can get location information
o Local sites of interest (Text, Audio and Video)
• User can also select (by appropriate category) other local multimedia information., namely:
o Businesses such as:
• Tourist Information Offices
• Bureau de Change
• Users can also book tickets online for Cinema and Theatre
1) Get a local map based on their GPS position
2) Search for a theatre
3) Book a cinema ticket
4) Get an audio description (guide) of a local point of interest
