Devices and methods are disclosed for generating input. In one implementation, a stylus is provided for generating writing input. The stylus includes an elongated body having a distal end, and a light source configured to project coherent light on an opposing surface adjacent the distal end. The stylus further includes at least one sensor configured to measure first reflections of the coherent light from the opposing surface while the distal end moves in contact with the opposing surface, and to measure second reflections of the coherent light from the opposing surface while the distal end moves above the opposing surface and out of contact with the opposing surface. The stylus also includes at least one processor configured to receive input from the at least one sensor and to enable determining three dimensional positions of the distal end based on the first reflections and the second reflections.

An information processing device according to an embodiment includes a control unit that performs: control of switching a display coordinate system of display content from a first display coordinate system to a second display coordinate system, the display content displayed on a surface of a real object by a display unit, depending on a state of an input operation of changing a position or an angle of the display content; and control of changing a display position or a display angle of the display content in accordance with the second display coordinate system and causing the display unit to display input assist display corresponding to axes of the second display coordinate system in a case where the display coordinate system is switched from the first display coordinate system to the second display coordinate system.

An information processing apparatus includes a control unit (140) that executes a detection process of detecting, on the basis of user-specified position information in a space and target position information in the space, a plurality of processing targets that is continuously selected by a user from a plurality of selection targets within the space, and a batch operation process of executing a batch operation on the detected plurality of processing targets on the basis of processing policy information indicating a processing policy specified by the user for the detected plurality of processing targets.

An information processing device includes: an acquisition unit and an association unit. The acquisition unit acquires first information, generated by processing a detection result which is output from a first sensor provided outside an electronic writing instrument, which includes a trajectory traced by the electronic writing instrument in writing of an object on a display image and second information, generated by processing a detection result which is output from a second sensor provided in the electronic writing instrument to detect a movement of the electronic writing instrument, which includes a trajectory traced by the electronic writing instrument in writing of the object on the display image. The association unit associates the object with the electronic writing instrument using the first information and the second information.

In an information processing apparatus (10a), a light emission control unit (34a) turns on IR LEDs (13) (light emission units) included in electronic pens (12) (operation bodies) in which communication with the information processing apparatus (10a) is established and blinks the IR LEDs (13) included in the electronic pens at timings different from each other in a case where another electronic pen (12) approaches. Then, a light emission recognition unit (32) (detection unit) detects a position according to the IR LED (13) included in each of the electronic pens (12) in association with the electronic pen (12). An input/output control unit (36) (display control unit) displays information associated with the electronic pen (12) at a position corresponding to the IR LED (13) detected by the light emission recognition unit in a case where the electronic pen (12) is in an information input state.

A method of controlling a projector includes projecting an achromatic area image representing a drawing area in which the projector receives drawing using a pointer on a projection surface at a first luminance at a ratio on the projection surface, the ratio being smaller than or equal to a specific ratio to a maximum luminance at which the projector capable of project an image on the projection surface, detecting a position on the projection surface pointed by the pointer while projecting the area image, determining whether or not the position is included in the drawing area, and displaying, by the projector, an area including at least a part of an outline of the drawing area at a luminance higher than the first luminance when it is determined that the position is included in the drawing area.

A method of controlling a display device includes the steps of displaying a first image in a first size on a display surface, displaying the first image and a second image which has the first size and is different from the first image on the display surface when an operation of changing a size of the first image is started, displaying the first image in the first size on the display surface when the operation continues, displaying the second image in a size different from the first size on the display surface based on the operation when the operation continues, and displaying the first image in a second size based on the operation on the display surface when the operation terminates.

A remote control device sends a patterned infrared signal to the display device. A display device receives the patterned infrared signal by using a plurality of infrared receivers. The display device obtains a projection pattern of the patterned infrared signal on a display screen. The display device determines a pointing position of the remote control device on the display screen based on the projection pattern. The display device displays a prompt mark in the pointing position of the display screen, where the prompt mark is used to prompt a user with the pointing position of the remote control device on the display screen.

An application control system and method is adapted for use with an entertainment system of a type including a display such as a monitor or TV and having display functions. A control device may be conveniently held by a user and employs an imager. The control system and method images the screen of the TV or other display to detect distinctive markers displayed on the screen. This information is transmitted to the entertainment system for control of an application or is used by the control device to control an application.
