Description

  The present invention relates to an electronic device control method using infrared detection, and in particular, detects an object using infrared light, determines a fluctuation waveform of movement of the object, and generates a control signal for controlling electronic equipment based on the waveform. On how to do.

  Sir William Herschel of Royal Society of England in 1800 announced that in addition to visible red light, in addition to the visible spectrum of red light, the infrared spectrum has expanded its application range and functions constantly. Among them, the main application is to use infrared rays for object detection. Thermal radiation includes a range that can be detected by an infrared sensor, and infrared sensors include those that detect human bodies and animals and plants depending on their types, and those that detect infrared rays of a specific wavelength emitted by mechanical devices. This further expands the application area. Among them, the applications often seen in general life are communication, anti-theft, photographing and detection of human body or object position, for example, “Human body detection automatic lighting device” of Patent Document 1, which is an infrared human body. It has a detection element, a light detection element, and a plurality of light-emitting diodes. When the light detection element detects a surrounding light beam, and when a light beam runs short and a person passes through the detection location, the infrared human body detection element outputs an infrared signal of the human body. The light emitting diode is detected and turned on for a certain period of time to achieve the illumination effect. From the background art described above and this Patent Document 1, it is understood that infrared rays have a function of detecting an object position. In another document, for example, “System and method for determining an input selected by a user using a virtual interface” in Patent Document 2, a virtual input interface is projected using a projection device, and a depth is calculated. Using the sensor, the position where the user clicked is determined, and thereby the signal input by the user is determined. Among them, the depth sensor is a sensor that detects infrared rays. However, this technology only uses infrared rays to detect the position of an object to be detected, such as a human body or other objects, and provides further control commands by moving the object to be detected, thereby enabling the application of infrared detection. There is no expansion. Further, another patent document 3 describes a signal conversion structure, which generates a corresponding signal table by using a CPU operation and memory, thereby converting the signal into another corresponding signal and providing it to the electronic device. . However, this Patent Document 3 does not describe a hardware structure to be combined for specific implementation.
