After the usability tests I developed Concept 2 and created a final prototype to show Elizabeth for feedback before I finalised the design.
Elizabeth exploring the final prototype.
Elizabeth made the following statements about the final design prototype:
“It’s just so much more ergonomic than the original one”
“The new features are all good improvements”
“It also looks so much better, I would leave this out on the work top”
The final prototype had a number of new features to improve the users experience.
- A stand has been included for users who want to keep the device on display; the top inner edge is chamfered for easy insertion of the device.
- There are switches on top so that the user can select which buttons will be active, any combination is possible and this addresses the issue of variability of condition between hands and could be useful for stroke victims.
- The screen is 30% larger than the orginal and the information is easier to read.
See Final Design blog post for full summary of the design features.
