Why does most our technology only engage two of our senses?

Question

Sight, hearing. Maybe you can count "thinking" too. But why don't we have technology that engages our other senses like touch, smell, taste?

Answer 1

i don't know if this counts but like touch, speech can also be used to input commands, like those GPS aboard cars that regconize verbal commands.

and what about those artificial arms and legs that people w/out limbs use (@ least those who are fortunate enough to afford them) that somehow work just like real arms and bend automatically when the user thinks about it

Answer 2

ummm, touch is kinda involved, because you touch the technology.

Answer 3

How about touch-screens? Yes, our sense of touch also engages to some  of our technologies. But smell and taste? Fat chance... That is because our main input devices are our sight and hearing, while our senses of taste and smell are for psychological concerns and that's what keeps our physical body alive.

A little off-the topic, but, actually, they are planning to have this BIO-identification system, in which process they are going to insert some kind of a microchip inside a part of your body and establishments that have BIO-sensor will be able to have your personal information. That is true, but I don't approve with things like that. That's satanism.

Answer 4

but smell and taste ? :S

maybe in 20 years or less, we will be using them xD
