5 futuristic interfaces

Steven Hodson

If tech related conferences are good for one thing it is to show of ideas and concepts that we probably won't ever see. While many ideas may work well in labs and during controlled presentations getting them into the wild in the hands of those terrible things called consumers usually happens only in the rarest of cases.

A good example of this is the following five futuristic type interfaces that will be presented at this year's ACM's Special Interest Group on Graphics and Interactive Techniques – otherwise known as SIGGRAPH 2009 – which is taking place in New Orleans this week.

Researchers, led by Hiroyuki Shinoda, from the University of Tokyo have developed a display that lets users touch objects that appear to float in space. This trick is done using and LCD and a concave mirror and the sensation of touch is recreated using an ultrasound device positioned below the mirror and LCD.
