Project - First Stage of Prototype Design

Contributors: Femma, Richard and Sven

Today, we started on the prototype design. We took out our paper and crayons and came up with a few physical designs. We took pictures of the drawings, however they came out a bit dark so we have also computerised them. Both images are below.

Sven's Design:




This design has a 3x2 inches rectangular paper screen display. It will have a plastic or glass (we haven't decided) cover to protect the screen. There is an 'up' and 'down' scroll button. The red button allows the user to back out of current mistakes and the 'enter' button allows the user to select what they want.

Here is Sven's original drawing:





Femma and Richard's Design:




(Note We bastardised the image from the seiko-epson website).

The display screen will be a 4x6cm square paper type display. The screen will be protected with either a plastic or glass cover. There will be a scrolling wheel on the right hand side, which is used like a mouse scroll wheel and pushes in to 'enter'. There will be a lock button on the left hand side, to prevent accidental scrolling. The scroll button will be quite tight so that a more stable control will be availabel. The strap will be made of an elasticated fabric so the messenger can wear it on the outside of their clothing in the winter and on their bare wrist in the summer.

Here is their original drawing:





We have one more protoype design, which Sven was working on but will be finished and blogged later (he had a C++ lecture).

The next stage is to design the functionality features.

All in all, it has been a pretty productive day. Here is Richard's reaction to the finished work:
