From "force" to "touch"
Some ads of "Haptics UI" for mobile in full spin in South Korea (Gimpo airport above and COEX center in Seoul below). The semantic of that word may be mysterious; from a Greek word which means “contact” or “touch” but it's definitely interesting to see it applied here.
In the 90s, it was often employed for the future of input/output interfaces in virtual realities; especially with a focus on force-feedback. Now, the emphasis is a bit more subtle and seems definitely on "touch": somehow the word made it by loosing the strength characteristic and turned into something more Weiser-ian: a calm "touch" computing paradigm.
