A method for controlling movement of a computer display cursor based on a point-of-aim of a pointing device within an interaction region includes projecting an image of a computer display to create the interaction region. At least one calibration point having a predetermined relation to the interaction region is established. A pointing line is directed to substantially pass through the calibration point while measuring a position of and an orientation of the pointing device. The pointing line has a predetermined relationship to the pointing device. Movement of the cursor is controlled within the interaction region using measurements of the position of and the orientation of the pointing device.

According to various embodiments, there is provided a pointing device for communicating with a computing device, the pointing device including: a switch operable to generate a control signal; a motion sensor configured to generate spatial data based on movements of a moveable part of the pointing device; a controller configured to inhibit transmission of the spatial data to the computing device, during a predetermined time interval immediately following a state change in the control signal.

A head-mounted device including a main frame couplable to an electronic device and a support part configured to affix the main frame to a facial side of the user, and an auxiliary input device including a body, an input module disposed on at least one surface of the body and configured to process an input signal for controlling a function of the electronic device, a sensor module disposed in the body and configured to obtain sensing information in accordance with a movement of the auxiliary input device, and a connection part electrically connectable to the electronic device and configured to serve as a path through which the input signal and the sensing information are transmitted to the electronic device is provided.

A rotating body, such as ball, disposed in a totem is selectively engaged and disengaged by a friction element to selectively restrict or allow motion of the totem on a touchscreen display. Engagement of the rotating body maintains a totem position on a touchscreen display, such as to support rotational inputs associated with a rotational user interface or to prevent the totem from sliding off the touchscreen display in response to tilting of the touchscreen display. Disengagement of the rotating body releases the totem to slide across the touchscreen display, such as to make inputs at a linear user interface.

The invention concerns a system comprising a touch sensor and a touch interactor, wherein the touch sensor comprises a touch sensitive surface configured to detect the position of a touch of an object on the touch sensitive surface, wherein the touch interactor comprises a support surface for placing the touch interactor on the touch sensitive surface and an activation member for generating a user input command for the touch sensor by its movement relative to the touch sensitive surface, wherein the touch interactor comprises an active detection point for transmitting an active signal, wherein the touch sensor is configured to determine a coverage, position, orientation and/or identity of the touch interactor on the basis of the active signal, when the touch interactor is placed on the touch sensitive surface.

An input device includes a housing, a wheel, a mode switch, a carrier, and an abutting assembly. The wheel is rotatably disposed on the housing and capable of rotating relative to the housing based on an axis. The wheel has a first gear structure and a second gear structure. The mode switch is disposed on the housing. The carrier is movably disposed on the housing and engaged with the mode switch. The abutting assembly is disposed on the carrier. While moving to a first position relative to the housing, the carrier switches the mode switch to a first mode and makes the abutting assembly contact the first gear structure. While moving to a second position relative to the housing, the carrier switches the mode switch to a second mode and makes the abutting assembly contact the second gear structure.

A haptic device with ultrasonic actuation, including: a support, a user-interaction element movable at least in rotation and/or translation relative to the support, a first contact surface that moves as one with the interaction element, a second contact surface that moves as one with the support, resonators, and a control unit that excites the resonators at at least one resonance frequency, generating a vibration mode in a plane and an ultrasonic lubrication phenomenon between the first contact surface and the second contact surface.

Systems and methods for controlling an elongate device include an input control console. The console includes a first input control having an infinite length of travel in a first direction, a second input control having an infinite length of travel in more than one direction, one or more transceivers for coupling the console to a control unit for the elongate device, and interface circuits for coupling the first input control and the second input control to the one or more transceivers. The first input control provides a first command suitable for controlling an insertion depth of the elongate device. The second input control provides second commands suitable for controlling steering of a distal end of the elongate device. In some embodiments, the console includes raised rings or bezels within which the input controls are mounted. In some embodiments, pockets of a drape are anchored to the raised rings or bezels.

Systems and methods for controlling an elongate device include a console. The console includes a first recess and a removable first input control for controlling motion of the medical device, The console also may include one or more first sensors located about the first recess that detect motion of the first input control and detect operator contact with the first input control. The console also may include an integrated display screen arranged to display status information for the medical device. In some embodiments, the first input control controls an insertion depth or steering of the medical device, and may be in the form of a scroll wheel forming a part of a removable control assembly
