Even if they get the latency/delay down to zero and have 100% accuracy, the primary issue for me will always be lack of physical feedback
. I can't stress how important it is to have physical feedback from all controls or input devices. People tried to make holographic keyboards (or completely flat keyboards) and nobody liked it due to the lack of physical feedback. You could make cars drivable with motion controls in the future but I guarantee almost nobody will like it - from the dawn of time time man has invented a control input, it has always been about the FEEL of those controls.
People LOVE pushing buttons, turning dials, pulling levers, flicking switches, clicking mice, etc! There is a wonderful sense of achievement when your control input gives you physical feedback to reassure you of what you've done.
(I'm personally a huge fan of giant brushed-aluminium volume dials on expensive stereos or amplifiers, secret guilty pleasure
Ask a surgeon how crucial it is for him to FEEL his tools in his fingers, to feel the resistance of cutting through flesh and fully grasp the precision of the situation. The very method of holding a scalpel is an art.
If you give him an ultra-precise robot and tell him to control that robot by wiggling his hands/fingers in the air (or a hologram), I guarantee you he'll say "...you're kidding right? I'll end up butchering something important and I won't even know it!"
Someone explain to me what this thing can do that a mouse + keyboard, or digital sketchpad + stylus, or a touchscreen already can't do better....remember all 3 of the things I have mentioned have excellent physical feedback, which is why they are so incredibly effective and have lasting appeal. I'm failing to see any appeal to this device.
The last time I waved my arms around in front of a Kinect to play a game my immediate thought was "this couldn't get any less immersive, what am I even doing?".Edited by Tippy - 1/18/13 at 11:24am
