Haptic technology in general not harmful to the human body and can be focused easily. One company called Ultrahaptics has been working with this technology to provide non-contact haptic feedback. Founded in 2013, Ultrahaptics has focused on providing users haptic feedback in free space using ultrasound technology. They use multiple ultrasound speakers to make changes in the air pressure around the user. This provides the ability to feel the pockets of pressurized air focused in the environment. This gives the user tactile cues for gestures, invisible interfaces, textures, and virtual objects. The company is continuing to grow and launched their evaluation programme
Haptic memory stimuli. According to a study done by Bruce V. DiMattia, Keith A. Posley and Joaquin M. Fuster, it was found that monkeys were quite capable of concurrent Visual-to-Haptic as well as Haptic-to-Visual crossmodal matching of objects by size, shape and texture. It was also discovered that they were more adept at performing cross modal matching in the Visual-to-Haptic direction. Memory is important in infancy as it forms the basis for more complex procedures such as learning and reasoning. Studies of haptic memory in infants is particularly useful because it allows researchers to study the more perceptual representation of information as
