The present disclosure provides an interactive device, an inductive screen, an interactive system, and a positioning method, and relates to the field of display technologies, with an objective of providing a low-cost positioning and interactive method. The interactive device includes: a first housing, a first end of the first housing having a light-exit opening; a first light-emitting component, arranged inside the first housing and configured to emit a linear light beam through the light-exit opening of the first housing, the linear light beam rotating with rotation of the first housing; and a driving component, connected to a second end of the first housing opposite to the first end and configured to drive the first housing to rotate.

Embodiments relate generally to electrical/electronic hardware, computer software, wired and wireless network communications, portable, wearable, and stationary media devices. RF transceivers and/or audio system in each media device may be used to wirelessly communicate between media devices and allow configuration and other data to be wirelessly transmitted from one media device to another media device. The proximity detection system may be configured to detect a presence of a user or multiple users and upon detecting presence, access content on a user device, and record the content while also playing back the content on the media device. One or more user devices in proximity of the media device post detection may wirelessly communicate with the media device and the media device may orchestrate handling and/or queuing of content from those devices or from a wirelessly accessible location such as the Cloud, Internet, NAS, Flash memory, or other wireless sources.

An operating method of an electronic system is provided. The operating method of the electronic system includes generating a first user input by a first input device and performing a first input control according to the first user input during a first input operation mode, determining whether a light intersection point of a ray emitted by a second input device with a virtual reality (VR) environment exists in the VR environment, switching to a second input operation mode in response to determining that the light intersection point of the ray with the VR environment exists in the VR environment and generating a second user input by the second input device and performing a second input control according to the second user input during the second input operation mode.

A control method for a display apparatus includes displaying a first image based on an input first image signal on a display surface when a first operation on the display surface is detected, displaying a first drawing image corresponding to the first operation on the display surface, when a second operation to select the first image and the first drawing image on the display surface is received, registering the first image and the first drawing image as a first group, and when a third operation to select the first group on the display surface is received, executing first processing corresponding to the third operation.

An electronic device includes a display for displaying data stored on the electronic device; input means; sensing means for sensing the three-dimensional position of the input means relative to the device; and control means for controlling the data displayed on the display in dependence on the three-dimensional position of the input means relative to the device. The input means includes a source of electromagnetic radiation for directing an infrared conical beam onto the display. The sensing means can sense the elliptical eccentricity of the electromagnetic radiation incident on the display to determine the angle at which it strikes the display, and can sense the area of the electromagnetic radiation incident on the display to determine the distance of the input means from the display.

There is provided an information processing device enabling reduction in cost and identification of input devices, the information processing device including: a light emission control unit that performs control such that a first light emission instruction is output to a first input device, if first identification information has been received from the first input device; and a processing unit that associates first light emission position information with the first identification information, if the first light emission position information has been acquired, the first light emission position information indicating a position where light has been emitted by a first light emission unit of the first input device.
