Description

Method and device for using infrared sensor to detect flipping of mobile phone to realize function switching

technical field

The invention specifically relates to a method and a device for using an infrared sensor to detect the flipping of a mobile phone to realize function switching.

Background technique

Electronic devices on the market today are basically controlled by physical buttons or mechanical switch devices. This control method is complicated, and the wear and tear on devices will affect the service life of electronic devices. For example, for mobile phone users, when a phone rings or vibrates when they are in a meeting or when it is inconvenient to answer the phone, they often set the silent mode except that they need to hang up directly in special cases. At this point, the user needs to pick up the phone and find the mute switch to set the incoming call to mute. The whole process includes: pick up the phone→unlock the keyboard→turn off the mute switch, which usually takes about 8 to 10 seconds. Not to mention the cumbersome process of this traditional control method, it also brings discomfort to users. Therefore, mobile phone users are badly in need of a method that can quickly and conveniently switch the mobile phone to the silent mode when the mobile phone receives a call.

Since the infrared sensing technology has been widely used in various electronic devices, how to use the infrared sensing device to realize the above functions has become an urgent problem to be solved. For example, the mobile phone user places the mobile phone on the table, and when there is an incoming call, the infrared sensor device detects the ambient light, and only one flip action is needed to switch the mobile phone to the silent mode, which will greatly increase the convenience and experience of the user; Not only that, compared with physical buttons, the flipping action will not cause wear and tear to the mobile phone, further increasing the service life of the mobile phone. However, there is no method of using an infrared sensing device to detect and receive infrared signals to realize function switching of the mobile phone after the mobile phone is turned over.

In the prior art, the publication number is CN201733358U, and the name of the utility model is: Infrared Intelligent Missed Call Reminder System. module, the mobile phone control chip is connected to the missed reminder module, and also includes: at least one infrared sensor that detects whether there are people around the mobile phone, and is respectively arranged on at least one side of the mobile phone, and the corresponding infrared sensor is connected to the mobile phone body. An optical filter is arranged on the side; and an infrared detection control chip is connected to the infrared sensor and the mobile phone control chip respectively. This utility model can intelligently design a system according to whether the user is next to the mobile phone, which is convenient for receiving missed calls and text messages in time, improves the function of effectively reminding missed calls and text messages, increases the reminder effect and reduces mobile phone consumption, and is humanized design. But this utility model only relates to prompting missed calls and short messages, and does not involve the application of infrared sensors to realize the function switching of mobile phones.

In addition, the publication number: CN101425306, the name of the invention is: infrared sensor control media playback device, the invention relates to an infrared sensor control media playback device, including a data processing unit, a display unit, a non-volatile storage unit, its The feature is that the media playing device also includes an infrared sensor capable of outputting an analog signal as the intensity of the external infrared signal changes, and the infrared sensor is connected with the data processing unit. The infrared sensor control media playback device can easily realize human-computer interaction with less or no energy consumption, and has high sensitivity, and can be widely used in fixed electronic equipment such as large computers and desktop computers and such as PDAs, mobile phones, MP3 and other portable electronic devices. However, the invention only relates to controlling the media player through an infrared sensor, and does not relate to a method for controlling function switching of a mobile phone.

In a word, in the prior art, there is a lack of a method for detecting the signal that the mobile phone has turned over by an infrared sensor device, and then realizing the function switching of the mobile phone.
