A: An interaction device, and a control method and apparatus. The interaction device comprises an infrared smart pen (2) and an infrared touch display (1). The infrared touch display (1) is provided with an infrared touch frame (11) which implements touch detection infrared signal reception, and a smart pen microprocessor (22) of the infrared smart pen (2) receives a current movement parameter sent by an acceleration detection unit (23), generates a page control command for performing an operation on a display page of the infrared touch display (1) according to the current movement parameter and sends the page control command to the infrared touch display (1) via an infrared signal. The present invention implements interaction device communication by means of infrared signals, increases the quality of communication between the smart pen and the display device, reduces signal interference, and generates commands on the basis of gesture recognition so that a user interaction process is more convenient.

The method comprises: according to a preset duration, setting cycles for an infrared touch screen to control an infrared touch frame (1) to perform scanning, one of two adjacent cycles being a touch cycle, the other being a data cycle (S110); within the touch cycle, controlling the infrared touch frame (1) to perform touch detection (S120); during the data cycle, controlling the infrared touch frame (1) to receive an infrared signal sent by an external data source of the infrared touch screen (S130); according to a result of the touch detection and/or the infrared signal, controlling display content of the infrared touch screen (S140). The infrared touch screen has a touch function as well as an external infrared signal receiving function, implements multiple functions on the basis of the same piece of hardware, and enhances functionality without increasing hardware costs, thereby ensuring the price advantage of the product, and increasing market competitiveness.
C: An interaction device, and an activation method and apparatus. The interaction device comprises an infrared smart pen (1) and an infrared touch display (2). The infrared touch display (2) comprises: a touch microprocessor (22), used for encoding smart pen recognition area information and transmitting to an infrared touch frame (21); the infrared touch frame (21), used for acting as a signal source for emitting an infrared signal carrying the smart pen recognition area information. The infrared smart pen (1) comprises: a first infrared receiver (12), used for receiving the infrared signal emitted by the infrared touch frame (21); an acceleration detection unit (11), used for detecting a current movement parameter of the infrared smart pen (1) and sending to a smart pen microprocessor (13); the smart pen microprocessor (13), used for decoding the infrared signal to obtain the smart pen recognition area information, and also for determining whether to activate the infrared smart pen (1) according to the current movement parameter and the smart pen recognition area information. The interaction device performs infrared communication, thereby enhancing the activation determination condition of the infrared smart pen, and decreasing the activation misjudgment probability.
D: An infrared signal transmission method and device and a remote controller. The method comprises: for each key of a remote controller, generating, a binary sequence corresponding to the key when it is pressed down (202); encoding and modulating the binary sequence to obtain a pulse train signal (204); sending at least two pulse train signals in the form of infrared signals before the key is released (206). The method solves the problem of poor anti-interference capability of remote controllers and low success rate of remote control existing in the technical solution involved in the background art; and increases the probability of the infrared signals being received completely, that is, improves the anti-interference capability of the remote controller and the success rate of remote control.
