Keyboard for head mounted display

The present invention relates to a keyboard, and more particularly to a keyboard for a head mounted display device.

Virtual reality (VR) is an active interactive display technology that generally needs to be used with a head-mounted display device. However, when the user wears the head-mounted display device, the view is completely obscured. It is not convenient to use the keyboard, so when you need to input a lot of text, you will encounter difficulties.

In order to solve this problem, the following solutions have been developed:

1. Click the virtual keyboard as an indicator: This input mode is to move the indicator in the virtual field of view by means of a joystick or a rotating head (or an external indicator input device: such as a mouse), and then click on the display by the head mounted display device. The keys on the virtual keyboard are input, but since the index is difficult to locate and only one button can be clicked at a time, the input efficiency is low.

Second, the input of the somatosensory: This method is represented by Intel Real Sense, which uses optical or muscle sensing to sense the movement of the user's finger, and then judges which buttons the user pressed, but this method The hardware cost of the cooperation is high, the software algorithm is complex, and it still has a low false positive rate. Therefore, it still has room for development and is not popular.

Third, the voice input method: Although the voice input technology has been developed for many years, the recognition rate is still unsatisfactory, especially in the noisy environment, the recognition rate is even lower, and the voice input is very troublesome to select words and correct errors. It is not convenient to use.

Therefore, how to input a large amount of text with a head-mounted display device is still the goal of current research and development.

Accordingly, it is an object of the present invention to provide a keyboard for a head mounted display device that can be applied to a head mounted display device that shields a full field of view and that provides quick input of a large amount of text.

Therefore, the keyboard for the head-mounted display device is applicable to a head-mounted display device that shields a full-view and can display a virtual keyboard, and the head-mounted display device receives a pressing signal and a touch signal and displays the The virtual keyboard includes a keyboard module and a position sensing module.

The keyboard module includes a plurality of button portions suitable for a user's two-handed pressing operation, and the keyboard module outputs the pressing signal related to the user's pressing operation.

The position sensing module is disposed on the keyboard module corresponding to the button portion for sensing a touch position and a touch track of the at least one finger, and outputting the touch signal related to the sensing result.

The utility model has the advantages that: by setting the button portion which can be pressed by the user's hands, and setting the touch position and the touch track of the finger by the position sensing module, and transmitting to the head mounted display device For display on the corresponding virtual keyboard, the user can "see" the position of the two-handed finger on the keyboard and which button portion is being pressed, so that the user can intuitively react and quickly and massively according to the visual feedback.
