An input device according to an embodiment includes a detection unit, a touch position number calculation unit, a vibration unit, and a vibration control unit. The detection unit detects one or more touch positions on an operation surface. The touch position number calculation unit calculates the number of the touch positions detected by the detection unit. The vibration unit vibrates the operation surface. The vibration control unit controls the vibration unit to provide different vibration modes depending on the number of the touch positions calculated by the touch position number calculation unit.

A process is disclosed of operating a user interface device configured to display an image on a display screen and enable user input by a user's finger touch on a touch screen in association with the displayed image, the process including: after the user starts a finger touch on the touch screen, if the user holds the finger at a substantially same location for a duration equal to or longer than a predetermined duration, initiating stationary displaying to display the image stationarily on the display screen, despite any later finger-slide motions on screen; and, after the stationary displaying starts, if a match is made between the finger's contact point on the touch screen and a location of a desirable graphical object included in the image displayed on the display screen, determining that the user has provisionally selected the object.

A system includes a sensor that detects motions of a first portion and a second portion of a body of a user, a controller that sets an association relationship between a coordinate system of a real space and a coordinate system of a virtual space in response to the motion of the first portion and receives an operation for an object in the virtual space in response to a position and the motion of the second portion, and a notification device that contactlessly notifies a third portion of the body of prescribed information.

Example methods and apparatus to provide haptic feedback for computing devices are disclosed. A disclosed example method includes presenting a menu having a plurality of menu items, receiving data representative of navigation of the menu items using a touch input device, processing the data to determine when menu items is navigated, and as the menu items are navigated, providing haptic feedbacks via the touch input device.

An input device includes: a touch sensor that detects a touch position touched by an operating body on an operation screen; a vibrator that is activated in an ultrasonic band to provide haptic feedback on the operation screen; and a controller that is electrically connected to the touch sensor and the vibrator. The controller receives an input made to the touch sensor through a gesture in a predetermined direction from an initial position, activates the vibrator when the touch sensor receives a shorter-in-length gesture in the predetermined direction from the initial position, and deactivates the vibrator when the touch sensor receives a longer-in-length gesture in the predetermined direction from the initial position.

Provided is a method of providing an image, the method including obtaining an image, extracting a haptic feature from an edge of the obtained image, generating a vibration pattern signal corresponding to the extracted haptic feature based on vibration pattern data, and generating vibration corresponding to a vibration generation request according to the generated vibration pattern signal when there is the vibration generation request.

A multi-modal touchpad can include: a touchscreen; at least one type of input sensor; a motion sensor; a haptic feedback device; and a multi-modal controller operably coupled with: the at least one type of input sensor so as to receive sensor data therefrom; the motion sensor so as to receive motion sensor data therefrom; the haptic feedback device so as to provide instructional haptic data to the haptic feedback device; a data interface that operably couples the multi-modal controller with an operating system of a device having the multi-modal touchpad; and a graphics user interface provided from the multi-modal controller to the display so as to display data from the multi-modal controller to the display. The at least one type of sensor can include a force sensor or a proximity sensor operably coupled with the physical sensing surface.

One illustrative system disclosed herein includes an enclosure configured to define a boundary of a chamber, the chamber including a material, and a flexible layer coupled overtop of the chamber and configured to enclose the chamber. The illustrative system also includes a first actuation device configured to receive a first haptic signal and responsively output a first haptic effect by changing a characteristic of the material to deform the flexible layer. The illustrative system also includes a second actuation device configured to receive a second haptic signal and responsively output a second haptic effect by applying an electrical signal to the flexible layer. The illustrative system further includes a processor in communication with the first actuation device and the second actuation device. The processor is configured to transmit the first haptic signal to the first actuation device and the second haptic signal to the second actuation device.

A display device comprises first and second pixels, a light-emitting layer, color conversion layers, and color filter layers, the light-emitting layer comprising first and second light-emitting elements in the first and second pixels, wherein the color conversion layers comprise first and second color conversion layers in the first and second pixels, the color filter layers comprise first and second color filter layers in the first and second pixels, the first and second light-emitting elements emit first light having a central wavelength range of a first wavelength, the first and second color conversion layers contain color conversion particles converting the first light into second light having a central wavelength range of a second wavelength longer than the first wavelength, the first color filter layer transmits the first light and blocks the second light, and the second color filter layer transmits the second light and blocks transmission of the first light.

A medical system may comprise a stereo display and an input device. The medical system may also comprise a processor configured to generate a three-dimensional image of an anatomical object and cause the three-dimensional image of the anatomical object and a two-dimensional window to be displayed. The processor may also be configured to cause a position and an orientation of the two-dimensional window relative to the three-dimensional image of the anatomical object to be changed on the stereo display by manipulation of the input device. The processor may also be configured to define a cut-plane to indicate a two-dimensional slice of the three-dimensional image of the anatomical object. The processor may also be configured to cause the two-dimensional slice of the three-dimensional image of the anatomical object to be displayed. An orientation of the displayed two-dimensional slice may be different than an orientation of the cut-plane with the three-dimensional image.
