The impact of sensor fusion on tilt interaction in a mobile map-based application
Bradley van Tonder, Janet Louise Wesson · 2011
Sensor-based interaction techniques relying on tilt gestures are increasingly being adopted in a wide range of mobile applications. Despite the recent increase in the availability of gyroscope sensors on mobile phones, most implementations of tilt interaction still rely on accelerometer input. Accelerometer sensors are susceptible to noise and also detect linear acceleration. This can lead to controllability problems, particularly when the user is mobile. This paper looks at how the fusion of accelerometer, gyroscope and digital compass sensor data impacts upon tilt interaction in a mobile map-based application. The results of an experiment comparing accelerometer-only tilt interaction with a sensor fusion approach are presented. The results show that while both the accelerometer and sensor fusion approaches performed well for seated tasks, the sensor fusion approach was shown to have advantages in terms of perceived controllability and efficiency while participants were walking.
