Description
In order to test our proposed (touch-less) interactions against the current (physical) ones, we are going to perform a user study which will measure the effectiveness of the fore mentioned interactions. A group of users will test our natural interactions in different scenarios. Live data gathered via direct observation will be analyzed, a questionnaire and an individual interview will follow.

Goals
- Analyze the naturalness of the proposed interactions
- Analyze the robustness of the whole concept
- Compare the parameters like distraction time, and reaction time of the proposed natural interaction method against the current method (using physical buttons)
Results from User Study questionnaire
Baseline comparison
NUI : Natural user interaction ( gestures + voice )
UNUI: Un-natural interaction ( buttons in steering wheel, cockpit)
User data
Number of subjects: 14
Training time : 4 minutes (each method)
Testing time : 4 minutes (each method)
Experience in driving: 12
Experience with motion devices: 9
In-game analysis
Collision:
- UNUI causes two times more collision
- NUI is safer while driving
Distraction time:
- NUI is 3 times less distractive
- Multiple modalities are more distractive
False positives:
- UNUI is twice more prone to errors
Interview
- 60 % people preferred NUI and 40 % prefer UNUI
- Idea is innovative, enjoyable, but needs more robustness
- Cognitive load is reduced considerably
