Mobile terminal capable of automatically adjusting volume and fonts and automatic adjusting method thereof

Abstract

The invention provides a mobile terminal capable of automatically adjusting volume and fonts and an automatic adjusting method thereof. The mobile terminal is provided with at least two range sensor modules and one camera module. The automatic adjusting method includes the steps that the data of the distance between a human body and the mobile terminal, measured by the first range sensor module and the second range sensor module and the relative positions of human eyes or human ears in a screen of the mobile terminal, recognized by the camera module are obtained; the first range sensor module is placed nearby the position of a telephone receiver of the mobile terminal, the second range sensor module is placed on the bottom of the front face of the mobile terminal, and the camera module is placed nearby the position of the first range sensor module; the azimuth-range of a human face or the human ears relative to the telephone receiver of the mobile terminal is calculated; then, the volume and the sizes of the fonts of the mobile terminal are automatically adjusted according to a preset control rule. By the aid of the mobile terminal for automatically adjusting the volume and the fonts, the volume and the sizes of the fonts can be accurately adjusted.

Description

technical field [0001] The invention relates to a mobile terminal capable of automatically adjusting volume and font and an automatic adjustment method thereof, in particular to a mobile terminal capable of automatically adjusting volume and font through precise positioning and an automatic adjustment method thereof. Background technique [0002] With the progress of society, portable terminals have become more and more popular. People use portable terminals in their daily life to make calls, enter text, play games, watch videos, etc. However, portable terminals usually only have a fixed volume and Text size, which may affect people with different habits of using the portable terminal, or people who use the portable terminal in different places (for example, bed, chair, etc.), or people with different motion states (moving or stationary) The volume and the size of the text do not match the distance from the user to the portable terminal. For example, the phone cannot be hear...

AI Technical Summary

Problems solved by technology

[0007] Only use the distance value between the object and the mobile terminal measured by the distance sensor as the basis for adjusting the volume and font, but the head of the person will face the mobile terminal, face the mobile terminal at an angle, or tilt the head in a crooked posture. Facing various situations of the mobile terminal, the distance sensor usually measures the distance between the point closest to the sensor and the distance sensor within the measurable spatial angle range of the distance sensor in the human head, so the measured The distance value is not the real distance between the human ear or the human eye and the mobile terminal, but the volume that a human can hear is related to the distance from the human ear rather than other parts of the head to the mobile terminal, and the font size that people can see clearly It is related to the distance from the human eyes rather than other parts of the head to the mobile terminal, so the volume and font adjustment will have large errors in different situations

[0008] Moreover, the adjustment of the above-mentioned device is not humanized enough, and unnecessary wrong adjustments are prone to occur.

[0009] In addition, when other objects appear within the measurement range of the distance sensor, there will be misoperations. For example, when the user uses a portable terminal to browse the web or watch e-books or video clips, sometimes the finger will flick in front of the distance measuring unit, or sometimes There will be other sundries around the head (such as lamp caps of desk lamps), then the distance measuring unit will mistake fingers, lamp caps, etc. as the user’s head, so the portable terminal will judge that the user is very close to the terminal Turning down the display font (and possibly the volume) so low that the user can't see what's being displayed (or can't hear what's being played)

In addition, when a person looks at the mobile terminal at a very oblique orientation, there may be a situation where the distance sensor near the earpiece cannot measure the person's head.
