Understanding behaviour when using large format touch screens
As part of a larger project, I looked into how users might use large 4k touch screens either individually or within groups.
As well as using existing research on screen interactions, I took a sample of people to establish an optimal height placement for the screen and the interfaces. The participants ranged in height from 5ft 2 inches to 6ft 4 inches. Consideration was also made for children and wheelchair users.
Low fidelity sketches on whiteboards were used for planning the layout and size of elements on the interface
