Problems solved by technology

However, the number of developers of such mobile phones and applications is small, and the service experience is not good; or the elderly may not buy elderly mobile phones out of the psychology of "not accepting the old". The elderly will use mobile phones eliminated by their children; even if they customize mobile phones for the elderly, operations such as font enlargement are still difficult and cumbersome for the elderly, especially when the elderly do a lot of text reading, such as chatting with their children, reading, etc. Very bad experience, definitely a vision challenge for the elderly

Embodiment Construction

[0039] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0040] The realization of the method of the present invention only needs to be used on a smart phone with a front camera with a fixed focal length, and at the same time, the hardware performance and operating system of the phone and the front camera need to be able to support face recognition calculations and ensure higher accuracy.

[0041] Such as figure 1 As shown, when using, turn on the smart phone device, once the screen on the smart phone lights up and enters or is in the scene interface of text reading, for example, the current mobile phone holder (hereinafter referred to as the user) uses the "WeChat" application to read a long paragraph Text messages, the front camera automatically opens and starts face recognition, without user input or preset any data parameters, directly calculates the user's fa...

Abstract

The invention discloses an adaptive font adjustment method and device for mobile phone text reading. The method comprises: carrying out face recognition of a user through a front-mounted camera, tracking and recording the latest facial information in real time, such as binocular distance, age, gender and whether the user wears glasses and other facial features data, further calculating the actualdistance between the screen and the user's eyes, and finally according to the actual distance and other factors, adjusting the display font suitable for the current user (especially the elderly) to read in real time. Compared with the prior art, the invention utilizes face recognition technology, the principle of optical imaging to automatically collect and calculates data, except for the mobile phone camera, other ranging elements are not needed, which makes the method and device suitable for most of the mobile phones on the market at present, the user is not required to actively input or preset the relevant value, and can automatically adjust the font display in real time according to the user posture change or the user individual change in one method cycle.

Description

technical field [0001] The invention belongs to the field of electronic information technology, and in particular relates to an adaptive font adjustment method and device for mobile phone text reading suitable for the elderly. Background technique [0002] In recent years, with the popularity of smart phones, more and more elderly people have come into contact with and gradually learned to use smart phones and mobile applications, such as using Android phones to play WeChat and Xiaoxiaole. However, the mobile phones and applications currently on the market are not completely suitable for the elderly, especially the elderly generally have weak eyesight and do not necessarily wear presbyopic glasses. The life of the elderly has brought stability, and at the same time it will undoubtedly cause more damage to the eyes of the elderly. If you do not pay attention or stop this behavior, it will cause amblyopia. [0003] In order to solve this problem, a relatively simple method is...
