Definition of "haptic"

So there may be sciences of touch, taste, and smell; which will be Haptic, Geustic and Osphrantic.

Although the five basic senses are often studied as individual systems covering visual, auditory, taste, smell, orientation and the haptic sensations, there is an interplay between the senses.

An engineer tends to describe haptics primarily in terms of forces, elongations, frequencies, mechanical tensions, and shear forces. This of course makes sense and is important for the technical design process. However haptics is more than that. Haptic perceptions range from minor interactions in everyday life, e.g., drinking from a glass or writing this text, to a means of social communication, e.g., shaking hands or giving someone a pat on the shoulder, and very personal and private interpersonal experiences.

[T]he new standard should encompass other media, such as video, audio (both captured and synthetic), and in principle be extensible to new modalities such as haptic output and speech or gestural input, which have become increasingly integrated within graphics applications; […]

We might think, for example, about tele- (or remote) surgery, a technique that, now more than ever before, is enabling surgeons around the world to operate using haptic interfaces that control robotic systems located at different locations.

Haptic feedback, or virtual touch, can also contribute to an IVE [immersive virtual environment] by providing forces or resistance with a physical device that resists a physical hand or finger. […] Vibration motors in smartphones and tablets can also be seen as a rudimentary form of haptic feedback.
