A steering means for vehicles suitable for use by disabled persons comprises an attachment device for receiving an upper limb of a person who does not have the ability to grasp the steering means. The attachment device comprises a hollow body in which are provided a seat to receive an extremity of the upper limb, a front opening, having an open outline, through which the limb projects when the extremity is received in the seat, a side opening, joined to the front opening, extending along the hollow body to allow the extremity of the limb to be inserted into or removed from the hollow body, respectively, as well as opposing abutment regions shaped and spaced so as to abut the extremity of the limb when the latter is subjected to a torsion movement.

Apparatus for controlling an object in real-time is described. In one aspect, an apparatus includes a frame, a bracket, and a stick controller. The frame is configured to be worn on a user's head and to inhibit relative movement between the frame and the user's head. The bracket extends from one or more portions of the frame and is positionable to extend to an area near the user's face with the frame is worn on the user's head. The stick controller is coupled to the bracket and being positionable for contact with user's face when the frame is worn on the user's head.

A head set is provided. The head set is beneficial for assisting an individual who is significantly impaired in the use of his or her upper extremities. The system enables this individual to move a cursor on a display of a computer or other processing device using lingual musculature. The head set includes a head piece. The head piece supports an articulating arm. The articulating arm supports a mouthpiece at a distal end. The mouthpiece has a plurality of cells embedded therein. The cells are configured to receive pressure applied by the tongue of the user. Movement of the tongue over and against the cells causes the cursor to be moved on the display. A method for moving a cursor on a display using a mouthpiece controlled through lingual movement is also provided. In addition, a method of typing characters on a virtual keyboard using lingual musculature is offered.

The invention is an apparatus for physically exchanging a force with a user in an environment local to the user. A connection element connects to a user's body member and a linkage between the connection element and ground. The linkage includes means for powering at least three independent freedoms of the connection element relative to ground and means for maintaining at least one independent freedom of the connection element relative to ground free of power. Up to three independent freedoms of the connection element may be maintained free of power, and up to five independent freedoms may be powered. Other aspects of the invention include a two actuator counter-balance for controlling a point on a link. The invention also includes apparatus for establishing a virtual, switch, which presents to the user the force and displacement relationship of a spring switch. Another embodiment is a virtual bristled brush, again which presents to the user the force and displacement relationship of such a brush, while also changing the virtual environment to reflect the user's changes in location.
摘要:
A method and apparatus for driving a computerized cursor through the translation of weight shifts of the human body. A force detection platform that detects small shifts in the center of gravity of the subject, electronically digitizes this information and then converts it to an analogue signal. This analogue signal is then fed into the generic joystick port of any personal computer and can be used to drive any existing software that incorporates use of a standard joystick.
摘要:
An apparatus and method for physically exchanging a force with a user in a user-local environment. The apparatus includes a user connection element and a linkage physically linking the user connection element to a reference. The linkage provides at least six independent degrees of freedom to the user connection element. The linkage has an actuator system which powers at least three degrees of freedom of the user connection element, while at least three degrees of freedom remain unpowered. The method includes providing an apparatus which includes a user connection element and a linkage physically linking the user connection element to a reference, the linkage providing at least six independent degrees of freedom to the user connection element. The linkage of the apparatus provided has an actuator system which powers at least three of the six independent degrees of freedom relative to the reference. The method further includes connecting the user connection element to a body member of a user and powering at least three of the six independent degrees of freedom.
摘要:
A connection element such as a thimble connects to a user's body member and, through a linkage, to a ground reference. The apparatus physically exchanges a force with a user in an environment local to the user. The linkage powers at least three independent freedoms of the connection element relative to the reference. It also maintains at least one independent freedom of the connection element relative to the reference free of power. Up to three independent freedoms of the connection element may be maintained free of power, and up to five independent freedoms may be powered. A gimbal connects the gimbal to the linkage. Zero, one or two of the gimbal axes may be powered. A five bar linkage connects the connection element to a counter-balance that also includes two actuators. A third actuator connects the five bar linkage to the reference. The two actuators of the counterbalance may be connected to the next link in the chain to the reference through a single cable. Signal processing equipment powers the actuators to deliver a signal at the connection element that represents a virtual situation generated by a programmed computer, or physical conditions in a remote environment. A virtual switch presents to the user the force and displacement relationship of a spring switch. A virtual bristled brush presents the force and displacement relationship of such a brush, while also changing the virtual environment to reflect the user's changes in location.
