The research paper discusses a method to generate specific vibration patterns on the surface of handheld electronic devices like smartphones, touch panels, and game controllers using a sparse actuator array. By studying the vibration characteristics of a single passive coil actuator, an optimal phase and amplitude modulation are found using the simulated annealing algorithm. This process allows for the creation of precise vibration patterns at any desired position on the device surface. The sparse actuator array can be easily embedded into handheld electronic devices, enhancing their haptic interaction capabilities.
