Embodiment 250

[0095] With respect to the mouse embodiment 250, three general types of tactile feedback are described; other types may be employed and may all utilize other types of tactile feedback devices (joystick, trackball, steering wheel, laptop sensor pad, etc. etc.) to achieve. The three general types of haptic feedback are button haptic feedback, inertial haptic feedback, and housing motion haptic feedback).

[0096] image 3 a-3c generally shows the output of the tactile feedback on the button. Button haptic feedback can be provided in several different ways. exist image 3 In a, the EAP actuator is utilized to provide tactile feedback and to actuate the motion of the button 256 along the button degrees of freedom shown by the arrows, i.e., in the direction of clicking or moving the button, where the button can be moved to another position as shown by the dashed line. a location. The EAP structure (not shown in the figures) may, for example, be directly coupled to the button, ...

Abstract

The present haptic feedback interface device uses electroactive polymer (EAP) actuators to provide haptic sensations and / or sensory capabilities. The tactile feedback interface device is in communication with the host computer (14) and includes a sensor (112) device for detecting user manipulation of the interface device and an electrical device for outputting to the user the force generated by the movement of the actuator in response to the input signal. Active polymer actuator (18). The output force provides a tactile sensation to the user. Various embodiments of interface devices using EAP actuators are described, including embodiments providing direct force, inertial force, and braking force.

Description

technical field [0001] The present invention relates generally to interface devices for interfacing a human with a computer system, and more particularly to low cost computer interface devices for enabling a user to provide input to a computer system and for the computer system to provide tactile feedback to the user. Background technique [0002] A user is able to interact with the environment displayed by the computer to perform various functions and tasks on the computer, such as playing games, experiencing a simulation system or a virtual reality environment, using a computer-aided design system, operating a graphical user interface (GUI), browsing the web, wait. Common human interface devices used for such interactive applications include mice, joysticks, trackballs, gaming keyboards, steering wheels, stylus pens, tablet tablets, pressure sensitive balls, and the like, connected to a computer that controls the displayed environment. on the computer system. Typically, ...
