Project 1 (part1)

MOTORAZR V3

This is the item I like.
It is extremely thin, light weight, and easy to use.
It also has a lot of functions like digital camera,

mp3 & video playback, wireless bluetooth, and etc.

visibility:

*External dimensions: 13.9 x 55 x 98 millimeters.
*2 display screen. ( internal & external )
*Full colour, bright and clear.
*Spun metal finish of the keypad.

feedback:

*The keypad gently reflect

the blue electro-luminescence light

with ‘beep‘ sound while the user presses a key.
*Current status and choices are displayed clearly on the screen.

affordance:

*External display shows the “Picture caller ID”

( info about the person calling with the user. )
*Internal display shows what will be happened next step

as some pictorial icons after pressing the buttons.

(easy to learn the control)

mapping:

*User can check the result of action

by 2.2 inch 176 x 220 pixel 64K color

TFT internal display. (this is large enough.)
*There is a round button

that arrows are forward to north, south, west, and east.

( easy to choose the icon. )

constraints:

*Short battery life.( usally it works only two days. )
*There is no cover cap for usb. ( makes dust problem. )
*Low memory ram. ( There is no additional memory card slot.)

habituation:

*The users can set their personal fuctions

such as message or browser at a key.
*Users also can change their layout,

screen saver, wallpaper, skin, and etc.
