Embodiment 380

[0172] The embodiment 380 also includes a flexible suspension that can be coupled to the middle plastic box 390 and can include two linkages 392 operatively coupled between the steel plate 388 and the ferromagnetic member 382 . Linkage 392 contacts steel sheet 388 at end 394 and is coupled to box layer 390 at end 396 (or is cast with the box layer as a single plastic piece). Each linkage includes a thinner part 398 and a thicker part 400 .

[0173] In operation, current flows through coil 384 and the magnetic force induced by the current and magnet 386 causes sheet 388 (and touchpad) to move in the direction indicated by arrow 402 . The suspension, including linkage 392, prevents tab 388 from deflecting due to normal magnetic or other forces. Each link 392 flexes to accommodate the movement of the sheet 388, with the thinner component 398 flexing first and the thicker component 400 flexing if the flex limit of the component 398 is reached. This thin-thick construction allows...

Abstract

A haptic feedback touch control to provide input to a computer. A touch input device includes a planar touch surface that provides position information to a computer based on a location of user contact. The computer can position a cursor in a displayed graphical environment based at least in part on the position information, or perform a different function. At least one actuator (336) is also coupled to the touch input device and outputs a force to provide a haptic sensation to the user. The actuator (336) can move the touchpad (332) laterally, or a separate surface member can be actuated. A flat E-core actuator, piezoelectric actuator, or other types of actuators can be used to provide forces. The touch input device can include multiple different regions to control different computer functions.

Description

[0001] This application is a divisional application of the following application: application number: 028062590 (PCT / US02 / 07102), application date: March 8, 2002, invention name: tactile interface for notebook computers and other portable devices. technical field [0002] The present invention relates generally to user interfaces with computers and mechanical devices, and more particularly to a device for interfacing with computer systems and electronic devices and providing tactile feedback to users. Background of the invention [0003] Humans interact with electronic and mechanical devices in various applications, and the demand for more natural, easy-to-use, and information-rich interfaces is always a concern. In the present invention, human beings interface with computer equipment for various application programs. One such application is interacting with computer-generated environments such as games, simulators and applications. Computer input devices such as mice and t...
