Exploration of tactile feedback in BI&A dashboards
2017
This paper describes the development of a vibrotactile feedback system for the representation of piecewise linear graphs. It defines the basic idea of the system and describes the hardware and software in the background. It then shows how the vibration patterns, that are transmitted to the user via a wristband with two vibration motors, are calculated from the data points of the graph. The system is evaluated by a brief study with five participants. Based on this evaluation the paper suggests how the system can be improved, extended and applied in different fields of data representation.
