1 Fitss law states that the ease of use of a control is proportional to size and inversely proportional to distance 2 This is why in many cases you will see mission critical systems “ surrounding ” the user 3 For modern digital interfaces, this means that factors like mouse travel distances or other gestural distances are important to a succesful design. 4 This is also why sound input is a way to reduce the friction of input - there is no “distance”. It is however diffifult to design for sound in high-noise environments.
