Tobii Rex has invented a new peripheral that you can simply attach to the bottom of your screen, and plug into your computer in any existing USB port. The company stated,”That you will purchase this along with any other peripheral that you would add to your computer.”
You probably will not be using this in the near future. His company will only be producing 5000 prototypes, and can be sold to developers for $995 each. This is device will not replace the standard keyboard mouse combo, but rather augment how they are used together.
This tech is still in developmental stage, but it is one of the many emerging technologies that we can look forward to seeing in the future.
