20110306425 | Haptic Interface - Controllers for user interaction with gaming consoles have progressively become more complicated and requiring good manual dexterity of the users to obtain the benefit of todays high resolution, virtual gaming worlds. However, even advanced users of such handheld controllers struggle to implement the required keystroke sequences required in these gaming environments. For those with disabilities, restricted motion, fatigue etc these controllers presented a barrier to their use of such systems. In accordance with embodiments of the invention a controller pad is provided that allows a user to select “buttons”, indicate motion etc with hands, feet, chin, mouth-held pointer etc. In some embodiments of the invention the controller pad also provides force feedback to the user in response to the actions of the user and/or computing environment either to increase the users overall satisfaction or providing stimulus to indicate errors or input requests in other non-gaming computer applications. | 12-15-2011 |
