Haptic motors are what most of us initially encountered in flip phones using a micromotor with an off-center weight on the shaft. The functions and locations are truly all over the place with end users increasingly coming into contact with haptics in medical devices, smartphones/tablets, and other touchscreens for gaming, sport fitness, and more. For gaming, home theaters, movie theaters, discotheques, and theme park rides, this “tactile” component is able to add a fourth dimension to reproduce the tactile impact of explosions, engine sounds, thunder, and other bone-rattling low-frequency content.įirst popularized by Pioneer more than 40 years ago with its Bodysonic bass shaker, used everywhere from discos to car seats, today’s haptics will give you a nudge when your smartphone is silenced, your Advanced Driver Assistance System (ADAS) will give you a poke when you are driving and feeling sleepy, or you might get a tactile “handshake” feedback from a touchscreen confirming your selection. These transducers pass low-frequency vibrations into them so that they can be felt.īass shakers have the power to intensify everything while improving the sensory interaction. Reproduction of this tactile component can be achieved through the use of a transducer popularly known as a “ bass shaker” coupled, sized, and tuned into the specific platform. ![]() Clinical studies have shown positive interaction with depression, PTSD, bipolar, insomnia, and autistic users. The smoothing vibrations of haptic therapies have proven in many clinical studies to calm the nervous system and improve heart rate variability (HRV) as a safe, non-invasive stress relief tool without drugs or side effects. The ability to perceive and interact with the world through vibration and touch contributes to the realism, and conversely haptics strengthen the illusion and simulation of reality. ![]() We promised to return to the topic and further explore tactile technology and the wide range of unconventional haptic applications. ![]() In the January 2021 issue of audioXpress, we provided a thorough exploration of bass shakers and haptic devices with a focus on music and home theater reproduction.
