Since we have talked about the concept of passthrough for two human senses — vision and hearing — it is logical to think about what other senses might be amenable to this paradigm. A logical candidate is touch.
One of the limitations of video and audio passthrough devices is the intangibility of the items they present us with. We can see and hear virtual objects, but we cannot touch them.
So perhaps we should be thinking in terms of “haptic passthrough”. In other words, by some technological means we should be able to touch virtual objects as though they are physical objects. In addition, we should be able to modify how real objects feel to the touch.
When combined with video and audio passthrough, the effects of this can be powerful. Taken together, all of these things constitute “multi-sensory passthrough”.
More tomorrow.
