Method for providing human input to a computer
DCFirst Claim
1. A touch interface comprising:
- a display screen including a front surface and adapted to display visually observable data;
a sensor circuit adapted to identify a characteristic of a touch input of a user on the front surface of the display screen; and
a force element responsive to the sensor circuit and adapted to excite the display screen by generating a force feedback signal in response to the characteristic of the touch input to provide tactile feedback to the user.

Abstract
The invention provides a method for providing human input to a computer which allows a user to interact with a display connected to the computer. The method includes the steps of placing a first target on a first portion of the user'"'"'s body, using an electro-optical sensing means, sensing data related to the location of the first target and data related to the location of a second portion of the user'"'"'s body, the first and second portions of the user'"'"'s body being movable relative to each other, providing an output of the electro-optical sensing means to the input of the computer, determining the location of the first target and the location of the second portion of the user'"'"'s body, and varying the output of the computer to the display based upon the determined locations for contemporaneous viewing by the user.

15. A computer implemented method for providing tactile feedback in response to input received from a user, the method comprising:
-
providing a touch screen including a front surface, the touch screen adapted to display visually observable data; providing a force element to actuate the touch screen with a tactile feedback signal; detecting a first touch input on the touch screen front surface; and actuating the touch screen front surface with the force element to provide a first tactile force feedback signal to the user in response to said detecting step. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A computer implemented method for providing tactile feedback in response to input received from a user, the method comprising:
-
providing a touch screen including a front surface, the touch screen adapted to display visually observable data; providing a force element to actuate the touch screen; detecting a first touch input on the touch screen front surface; determining a characteristic of the first touch input; actuating the touch screen front surface with the force element to provide a first force feedback signal in response to said detecting step; detecting a second touch input; determining a characteristic of the second touch input different from the characteristic of the first touch input; and actuating the touch screen front surface with a second force feedback signal different from the first force feedback signal. - View Dependent Claims (32, 33, 34, 35, 36)
