Abstract: An ergonomic apparatus for generating data signals that may be indicative of alphanumeric characters for use with an electronic device or system such as a computer or electric typewriter, for example. The apparatus may be configured in accordance with ergonomic principles and use one or two hands to generate the data signals. The apparatus may include a set of domes that are shaped and contoured to conform to the shape of hands in a relaxed state and to distribute pressures across the splayed underside of the user's hand. Each dome may be capable of movement in a plurality of directions extending radially from a home position to generate the data signal or a portion of the data signal. The two-handed implementation disclosed utilizes input movements that enable keystroke actuation via only slight arm or hand movement, no finger movement being required.

Abstract: A handheld device having a main body and at least one button integral with the main body for causing generation of electrical signals. A pair of thumb controllers may be integral with the main body and positioned so that a user holding the device may tactilely engage each of the thumb controllers. A pair of sensing means may be operatively connected with the thumb controllers to generate an electrical signal in response to the user's tactile engagement with the thumb controllers. The signals may be resolved by a processor to determine an alphanumeric character to be generated. The signals may also be resolved with a signal generate by movement of the button to determine a state change to be generated in a video game so a user may interact with the video game. An electrical signal indicative of the video game state change may be generated and transmitted to a processing device executing the video game.
