- Paper Prototyping - ----------------- - Prototype an interface for an older, simpler, style handheld device which - doesn't support popup windows or pull down menus. Develop a telephone - interface which allows the user to enter numbers, call the number, store - and retrieve numbers, correct entered numbers, and add text which can be - associated with the number for names or short comments. - - Since there are no menus you will need to show all functionality - on the screen and design a method for the user to access it - through the keypad. There is no touchscreen. - - The phone has a 12 button numeric keypad where all 26 letters - can be accessed through the keys. There are also three buttons for up arrow, - down arrow, and enter. The comma, period, and a shift key can be accessed - through the 12 buttons as well. Design a method which allows all of the - characters to be selected using the limited number of buttons. Decide - which characters are on which buttons and how they are accessed. - - The interface has the ability to display lists of records which the - user can scroll through. There should be some way for the phone - to display messages to the user. Probably a static message field - on the screen but you can think of other solutions. - - Once it is done get one or more people from another group - to interact with the interface and try to use it. - - Work in groups of three or four. - - The lab is worth 5 marks. -
