The PlayStation 4 could be receiving an upgraded Move controller. Sony filed a new patent for the PlayStation Move controller that supposedly heats up and cools down in your hands.
The temperature of the controller will change depending on the action within the game. For example if playing a FPS such as Call of Duty and your gun overheats, your controller also increases in temperature.
“As the weapon heats up, the controller light may change from a cooler color to a warmer color, such as from blue or green to orange or red. Similarly, when the weapon cools down, the color exhibited may revert to the cooler color,” the patent reads.
Sony has not announced this technology yet, and there is no clear indication if this will be first introduced for the PS3 or PlayStation 4.
