Why Digital Signal Processing Is the Key Requirement for HD Haptics
Haptic technologies offer tremendous potential for delivering immersive experiences for games, movies, music and more. By supplementing audiovisual content with tactile vibrations, haptic technologies can enhance sensory stimulation and increase user engagement.
Many hardware platform vendors have integrated basic haptics into their products. Using simple actuators, they have created game controllers that produce low rumbles or smartphones that generate buzzing alerts. But next-generation high-definition (HD) haptics requires more than hardware alone. Incorporating software into haptic systems is critical for overcoming limitations of hardware-only solutions.
Software-based digital signal processing (DSP), running as firmware on embedded processors, optimizes signals used by the actuators
