DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to sensing, and to the control of computer controlled systems, such as visual displays, using position or movement sensing devices such as joysticks.
BACKGROUND ART
Various devices have been used to control the movement of objects on computer screens, both in the context of games and of application software. Examples include various forms of joystick, mouse and trackball devices. These all provide a simulated movement on the screen in response to a change in position of mechanical parts on the device, for example movement of the ball in a mouse or trackball.
More recently, various devices have been proposed for use in so-called virtual reality systems. These devices tend to be expensive, and rely on complex sensor arrangements arranged in a glove or the like, hard wired to a relatively powerful processor. Such devices rely on a triangulation method to locate the hand held or operated part within a limited field.
All of the above devices provide raw data which is processed by the main computer system, so as to provide movements of images on the screen.
It is an object of the present invention to provide a control system and method, which utilises the positional, attitudinal, movement or similar data to provide additional features for the overall system.
SUMMARY OF INVENTION
According to one aspect the present invention provides a method of processing sensor data produced by a sensing system, said sensor data having a plurality of possible values for each parameter sensed, at least one of said parameters being related to position, attitude or movement of an object, characterised in that for at least one of said parameters related to position, attitude or movement of an object, said sensor data is processed according to a predetermined instruction set, said predetermined instruction set being also responsive to at least one of the group comprising previous values of said parameter, and current or previous values of other parameters, so as to produce output data belonging to a set of possible output data values relating to said parameter, said set including values not directly corresponding to said sensor.
According to a further aspect the present invention provides a system for controlling a computing system, said system including at least one display means, first processing means controlling said display means, and a remote control device adapted to control at least one of the images displayed on said display means, said remote device including a sensing array adapted to produce sensor data corresponding to desired movements of an image on said display means, said sensor data having a plurality of possible values for each parameter sensed, at least one of said parameters being related to position, attitude or movement of an object of the remote device or a part thereof, characterised in that for at least one of said parameters related to position, attitude or movement of the remote device or a part thereof, said sensor data is processed according to a predetermined instruction set, said predetermined instruction set being also responsive to at least one of the group comprising previous values of said parameter, and current or previous values of other parameters, so as to produce output data belonging to a set of possible output data values relating to said parameter, said set including values not directly corresponding to said sensor data, said output data being used by said processing means to control images on said display means.
The present invention utilises the sensor data, produced from sources ranging from analog joystick, attitude sensors, virtual reality sensors of various types, mouse type devices and other related position, movement or attitude sensing arrangements, to do more than simply control a screen image in accordance with the go left, go right, type instruction produced. The present invention, in a preferred implementation, allows extra states not defined by the sensor outputs to be produced on the screen, either pre-emptively (for examp
