28. NUI Hopes
28/30
‣ Natural - almost invisible
‣ Direct - based on intuition
‣ Simple - no need to learn new device
‣ Easy - fast to learn (intuition, again)
‣ Physical - feel more natural
29. NUI Worries
29/30
‣ Culture - cultural differences, acceptance in society
‣ Abstraction - we still use metaphors
‣ Ergonomics - “put your hands up in the air”
‣ Cross-platform - “in the UK, the people switch devices 21
times per hour (TV and smartphone). 90% of people move
between devices and use them simultaneously”*
‣ CLI, GUI - are current GUIs so unnatural?
