ABSTRACT
Tactile feedback can be a particularly effective way to communicate information to people while they perform tasks, especially when other communication means are unavailable or when senses other than touch are overloaded. Insufficient tactile feedback can cause dangerous uncertainty. Some touchscreen-based devices have addressed the shortcoming by providing haptic feedback—a way of simulating tactile sensations through vibrations or other motions—to inform the user that the input was received. Provide tactile feedback such as vibration, resistance, and texture when visual and/or audible feedback is impossible or ineffective. Tactile Ground Surface Indicators are used to assist vision-impaired pedestrians. The textures are noticeable by a long cane or by foot, and warn pedestrians of approaching streets or hazardous situations. As aircrafts became more advanced and control systems insulated pilots from signs of a stall, pilots lost the tactile feedback necessary to rapidly recognize and correct a stall.
