Considerations and Justifications for Choice
The back of the raspberry pi touchscreen is not a flat surface as the raspberry pi is attached to it. Hence, a support structure to prop the screen up is required so that the wires at the back can be connected to the raspberry pi smoothly. Furthermore, it is more user-friendly to have the display propped up at a certain angle as compared to having it flat on the table.
Prototyping Process: Cycle of Test, Critique and Re-Design
V1
The holder is a skeleton support.
V2
Identified Issues with Previous Prototype (Critique):
- Raspberry Pi touchscreen display is slanted at an angle
- Touchscreen display is not secured and might slide off
Modifications Made (Redesign):
- Downloaded template [1] and printed
- Template is more secure and touchscreen display is enclosed in a casing.
