Visual prototyping

 3D designed & rendered prototypes based on:

• Dimensions from 'dinbelg.be': average & percentile dimensions of the human body
• Quad industries components (metal domes, ...)
• Finger radius & angle

 Flat simple test pads to be made for performance tests

 Middle row of flat buttons, top and bottom row perpendicular

 Pad composed of 5 equal segments with 3 buttons each, for modularity

 Double curved prototypes for better ergonomics

 Pads with embossing for each button, for better finger guiding
