Abstract

Current gaming input devices on cellular handsets use 4 and 5-way navigation buttons. While suitable for basic gaming, these navigation buttons do not allow the 360° input capability that home gaming consoles, such as Playstation® and X-Box®, are capable of supporting. In console based first person or driving games, the player has 360° control over the direction their character/vehicle looks/moves

Abstract:

Current gaming input devices on cellular handsets use 4 and 5-way navigation buttons.  While suitable for basic gaming, these navigation buttons do not allow the 360° input capability that home gaming consoles, such as Playstation® and X-Box®, are capable of supporting.  In console based first person or driving games, the player has 360° control over the direction their character/vehicle looks/moves.  This control is accomplished with a pair of analog joysticks.  An analog joystick is a 2-axis control device.  While suitable for single purpose, console-based controllers, these devices are considered too large (at approximately 26.5mm X 21.5mm X 12.2mm) for integration into a cellular handset.  The packaging challenge is even greater if a pair of joysticks, as in console-based game controllers, is needed.  If two joysticks are integrated, the use case for gaming would result in reorientation of the handset from portrait to landscape to provide acceptable ergonomics.  As cellular phones have earpiece speakers to facilitate auditory feedback during calls, the area normally occupied by the earpiece speaker would be infringed upon by the joystick.  Additionally, there are minimum levels of acoustic qualities which must be achieved.  Gaming is becoming a popular feature on cellular handsets.  Thus, a solution which provides 360° joystick input and acceptable earpiece acoustic characteristics is desired.

Recent development efforts in the control industry have yielded a device which provides 360° input capability in a small package:  the MicroNav® by Interlink Electronics.  MicroNav® is based on force sensing resistor (fsr) technology and is approximately 10mm X 10mm X 2.2mm.  This document contains a method for integrating a joystick into the earpiece area of a portable cellular handset.
