A patent that Sony filed back in June 2012 has been published on the USPTO (United States Patent and Trademark Office) site. The patent was filed for a product called the Flat Joystick Controller, which looks to be an upgraded Move controller featuring touch pads:
According to the abstract on the site:
A controller device to interface with a computer gaming system includes a body having a handle and an object disposed at one end of the handle. A touch surface is disposed on one side of the handle. The touch surface has an indicator that is identified by a surface characteristic on the touch surface. The touch surface provides an area for receiving directionality control in response to interfacing by a finger of a user. In addition to the touch surface, a plurality of buttons are disposed on the body. A circuitry is disposed in the body of the controller. The circuitry is configured to receive data indicative of a directionality control and transmit the data to a game console for impacting an action by a program executing on the computer gaming system.
Sony’s reasoning for the inclusion of touch pads is that it can be difficult for players to keep their thumb still on a Joystick on the Move or any other motion controller, while said controller is moving around. According to Sony, a touch pad interface would alleviate those issues.
This new controller would most likely be for their newly released PS4. Meanwhile, check out the gallery below for more info and diagrams depicting the Flat Joystick Controller.
