A brief photo-snap of the blue foam prototyping process. The scale of the blue foam model is 1:1. From the blue foam model I realised that when using the knobs, my fingers were coming into contact with the other knob and the chamfered radio face trim on the right hand side. I needed to increase the height and width of my design by 5mm and decrease depth/outer lip by 5mm. Subsequently the distance between the knobs/buttons would increase by 5mm, allowing for more room for the user to grip the knobs.
