Abstract

Haptic feedback provides an eective means of transferring information through tactile stimulation. In this work we look into the use of tactors for haptic feedback in body-worn contexts where individuals are allowed to move around. In this context it is crucial to design low power systems that al- low the activation of multiple tactors at the same time with limited battery power. We investigate how to minimize tac- tor power consumption by tuning the characteristics of their excitatory signal and present an activation policy to maxi- mize the number of tactors that can be simultaneously pow- ered by a battery under a tight peak current constraint.The proposed optimizations reduce power consumption and al- low a much higher number of simultaneously active tactors. Furthermore, we provide a design strategy whereby design- ers can tune the maximum number of simultaneously allowed active tactors based on battery and system requirements.
