Energy Flow: A Multimodal 'Ready' Indication For Electric Vehicles
Adjunct Proceedings of the 6th International Conference on Automotive User Interfaces and Interactive Vehicular Applications, AutomotiveUI '14. Seattle, WA, USA, September 17 - 19, 2014.

The lack of sound and vibration while starting the drive system of an electric vehicle (EV) is one of the major differences compared to a conventional car with a combustion engine. Most EVs provide a visual feedback about the energy level to the driver. With Energy Flow (see Figure 1), we test if there will be a benefit in terms of attractiveness through adding audible or haptic feedback. First results show a positive effect by addressing several senses -- but disprove the hypothesis "the more the merrier".
