Natural User Interfaces
Gideon Steinberg · 2012
In this report I have discuss the works of 6 papers in the field of natural user interfaces. They all discuss different interaction techniques and how effective they are. Most of the current literatures, within 4-5 years discuss techniques for touch screens or movement based interaction, so I will be focusing on these topics. Fitts's Law is a huge part in all Human Computer Interaction. Fitts's Law states that completion time is proportional to distance and size of the target[7]. This is important when trying to make user interfaces natural, as we can apply applications of Fitts's Law to make the user interfaces easier to use. When creating a natural user interface we need to decide what type of interaction techniques we should use. We need to decide on bimanual versus unimanual input. Bimanual is faster than unimanual, but it is not always possible to have bimanual input. There is a lot of literature on touch screens and wall displays. This report covers many types of these interactions. It covers physical navigation, tactile feedback and many gestures. It seems that tactile feedback is not a natural form of output as it tends to distract the user. Physical navigation is a great way of helping the user navigate a virtual space.
