The haptics term comes from the Greek \u201chaptikos\u201d meaning \u201cconcerning the sense of touch\u201d. In the tech world haptics identifies all the technologies that provide the sensation of digital touch feedback, also called haptic feedback.<\/p>

Haptics is a particular technology because it is bidirectional. It involves an action (interaction) and a reaction (haptic feedback). Specifically, the action is the intention of the user to interact with a haptics-enabled content. The reaction is the haptic feedback that the digital content transmits to the user.<\/p>

This is one of the key aspects of haptics: interaction is almost as important as the haptic feedback. Haptics is successful when it is included in the design process of your applications.<\/p>

Haptic feedback covers a wide range of possible stimulation embodiments but is broadly divided into tactile haptics technology and kinesthetic haptics technology. Tactile haptic feedback refers to sensations such as vibration, friction, or micro-deformation. Kinesthetic haptic feedback refers to sensations that provide force sensations that can stimulate both mechanical stimuli as well as stimuli related to the position and the movement of the body.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Vibrotactile technology is probably the most widespread kind of technology used in haptics devices. Typical solutions include the rumble-like feeling of ERMs<\/a> (Eccentric Rotating Mass) towards more expressive LRAs<\/a> (Linear Resonant Actuators), and large bandwidth actuators like VCM<\/a> (Voice Coil Motors), or PZT<\/a> (Piezoelectric Actuators). Devices equipped with these actuators are able to consistently deliver vibration patterns, which are useful to enhance user experience during interactive scenarios. Vibration effects can be thought of as a kind of audio for the skin.\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
