ABSTRACT
We present the design and implementation of a solenoid based haptics device, which weighs less than 100 grams, and generates a acceleration of 14-g for simulating impact events in virtual reality and games. The device is used in free air, or ungrounded, and generates the high-g impacts without being attached to a large structure. The goal is to generate a more realistic impact sensations than commonly used vibration motors. The device consists of two solenoids in push-pull configuration. A low internal resistance battery system supplies high-current pulses of more than 10 amperes. During user motions, one solenoid will magnetically holds the device in ready position, so that the other solenoid achieves maximum stroke and impact output.
