Problems solved by technology

[0004] It can be seen from the above description that the existing handwriting input method requires special processing on the display screen so that it can sense pressure changes or magnetic force changes, which increases the cost of handwriting equipment; furthermore, once the external stylus is lost , will result in the inability to perform handwriting input, causing inconvenience in the use of handwriting devices

Embodiment Construction

[0053] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0054] In the embodiment of the present invention, it is considered to set up a camera to remotely capture the user's handwriting input to obtain handwriting input images, and to recognize the user's handwriting input through a preset handwriting input recognition module to avoid special processing on the display screen. The STB is taken as an example for description below.

[0055] figure 1 It is a schematic flowchart of a handwriting input method for STB according to an embodiment of the present invention. see figure 1 The process includes:

[0056] Step 101, using a camera to obtain a user's handwritten input image;

[0057] In this step, a built-in camera can be built into the STB. Of course, in practical applications, the camera ...

Abstract

The invention discloses a handwriting input method for a digital television receiving terminal, which comprises the following steps of: acquiring a user handwriting input image by using a camera; and performing image frame identification on the acquired user handwriting input image, matching the identification result of one-time complete input operation and a preset handwriting input identification model, and outputting the matching result. The invention also discloses a handwriting input device and a handwriting input system for the digital television receiving terminal. The method, the device and the system can lower the cost of the digital television receiving terminal, and are favorable for the implementation of interactive service.

Description

technical field [0001] The invention relates to handwriting input technology, in particular to a handwriting input method, device and system for a digital TV receiving terminal. Background technique [0002] The current digital TV receiving terminal, such as a set-top box (STB, Set-Top Box), generally uses input methods such as pinyin input and stroke input to input Chinese commands through the remote control or the STB display screen, and performs corresponding operations on the STB. With the increasing demand for interaction, the problem of "thumb fatigue" caused by pinyin input and stroke input is gradually exposed, and the input efficiency is low. [0003] In order to overcome the technical problem of "thumb fatigue" and improve input efficiency, the prior art proposes handwriting input technology. Handwriting input refers to handwriting on the display screen of the device through an external stylus such as a mobile phone. Perceive the position of the handwriting contac...
