This is hardly a "touchable" hologram, more like sensory relayed positioning information. The ball/button is projected at coordinates x-y-z once a hand(or other object) moves to coordinates x-y-z the sensors record the data and the hologram is "touched." You aren't however going to FEEL the hologram.
Quoting: Anonymous Coward 975472 lol if you think he is touching a hologram
you fucking morans
Quoting: Anonymous Coward 830513 This is a touchable hologram. To understand that you must first understand what touch actually is - the somatasensory system and sensory receptors.
When you touch something -how does the body know what it feels? Sensory receptors are structures that respond to changes in the environment. A change in the environment would be any stimuli. In this case the stimli is ultrasonic waves that create pressure. The sensory receptors in the periphery will detect the stimuli, and then sensation & interpretation take place in the brain.
When we "touch" the hologram object as far as our bodies' proprioceptors are concerned, we are "touching" that object. They have created a feeback system to stimulate a proprioceptive response in the body - nothing new-
Haptic technology - [
link to en.wikipedia.org] "a tactile feedback technology that takes advantage of a user's sense of touch by applying forces, vibrations, or motions to the user."
By combining sense of touch to our visual hologram we are stimulating more and more of our somatasensory systems and creating a more "real" virtual holographic reality to immerse ourselves in.
This simulated sense of touch to define the animated holographic object is no different that your simulated sense of touch that defines objects in your environment.
