Ultrahaptics, the mid-air haptic feedback technology company, has been shortlisted for the Ultimate Product Software award by the judging panel of the 2016 ACE Awards. The award recognises the most significant software product introduced between January 1, 2015, and June 30, 2016.
The Ultrahaptics’ Software Development Kit Version 2 uses algorithms to allow users to receive tactile feedback in mid-air without needing to wear or touch anything. The ‘feeling’ of an object is created by using an array of ultrasound transducers to generate and focus ultrasound which stimulate neuroreceptors in the skin. The carrier frequency for the ultrasound is 40 kHz due to transducer availability, propagation and audible properties. In order for human skin to detect the vibration, the 40 kHz ultrasound is modulated at a lower frequency within the perceptual range of feeling; the Ultrahaptics system typically uses 100-300 Hz corresponding to the peak sensitivity of the tactile receptors. Modulation frequency is one of the parameters that can be adjusted by the API to create different sensations. The location of the focal point, determined by its three-dimensional coordinates is programmed through the system’s API.
