Description

Remote controller with integrated information input and display function and application method thereof

The invention belongs to the information processing technology of the remote control interactive device in the technical field of digital television, and particularly relates to a remote controller integrated with information input and display functions and an application method thereof.

technical background

As a new and efficient means of information dissemination, digital TV has been recognized by the public. Compared with traditional TV broadcasting, digital TV has the characteristics of clear images and rich content, and interactive digital TV uses digital TV platform to introduce various interactive programs. And services have increased the practicality and interactivity of digital TV. At the same time, the amount of information exchanged between the user and the system is greatly increased by the interactive digital television, and the user's use of the remote controller is developed from the simple adjustment of the channel volume and menu navigation of the ordinary digital television to the comparison of text and digital input. Complex operation. The ever-increasing content of the program and the increasing complexity of the menu structure make it more difficult for users to obtain and select digital TV content information.

Ordinary digital TV remote control evolved from the traditional TV remote control. Generally, various navigation buttons and shortcut keys are added on the basis of the traditional remote control to facilitate the user to operate the digital TV, and the digital key is re- Define to complete the input of information in Chinese, English, numbers or other content. There are many buttons on the remote control, which is not easy to remember, so users often have to look at the remote control to operate. Since ordinary digital TVs mainly focus on viewing and browsing content, there is no problem for users to use such remote controllers for simple digital television operations, and interactive digital televisions allow users to perform complicated information input operations, and at the same time, due to the input of the remote controller. The interface and the display interface are not together, and the user needs to frequently switch between the two interfaces. The left half of Figure 1 shows the use of the existing remote control. Users need to pay attention to the remote control when performing interactive operations such as text input and digital TV interactive service content selection.

Confirmation After operation 11, after the remote controller sends the operation signal 12 to the controlled device, the user needs to view the operation feedback and view information 13 from the interface of the controlled device, and then perform the next operation 11 on the remote controller. For example, when the user needs to input Chinese characters by some input method, it is necessary to observe whether the content displayed on the screen is correct every time a letter key is pressed, and then find the next button on the remote controller and press it again, after inputting the code. Use the navigation keys and the confirmation button to select characters. In this process, the user needs to repeatedly look up the TV screen and look down at the remote control. After a period of time, it is easy to cause poor user experience and even physical and mental fatigue. The advantages of interactive digital TV are likely to be lost due to the limitations of the remote control.

On the other hand, users of handheld mobile terminals such as cell phones and personal digital assistants (PDAs) often need to browse and enter information, and the exchange of such information is very convenient and efficient. Compared with the remote controller, the information input device (such as a keyboard or virtual keyboard) and the information display device (such as a screen) of the handheld mobile terminal are in close proximity or even integrated, and the user's attention is concentrated on one palm. In terms of location, there is no need to frequently switch between several device interfaces, and the efficiency and comfort are naturally improved. If the display is also set on the remote control, allowing the user to perform small-scale information browsing, input and proofreading, and then send the control commands and input information to the digital TV as a whole, the information acquisition of the interactive digital TV user will be The input brings great convenience.

To enable content browsing and input on the remote control, the remote controller needs to have corresponding information storage and processing capabilities; sometimes, two-way data exchange between the controlled device (such as a digital TV set-top box) and the remote controller is required, the existing Wireless signal technologies, such as WIFI, Bluetooth, and infrared, enable high-speed data transmission between devices. In addition to being used in digital TV, this type of remote control can also be used in other systems that require the user to use the remote control to control the device and to exchange certain information.

Summary of the invention SUMMARY OF THE INVENTION An object of the present invention is to overcome the deficiencies of the prior art and to provide a remote controller that integrates information input and display functions, that is, a device that integrates information processing and display devices on a remote controller.
