CN201754203U - Liquid crystal glasses with dynamic visual angle - Google Patents

Abstract

The utility model discloses liquid crystal glasses which can dynamically regulate the observation visual angle along with the rotation of the human head. The liquid crystal glasses are embedded with a triaxial inertial sensor which can transfer the rotation direction of the human head to video terminal equipment by utilizing the attitude measurement function; and the video terminal equipment regulates the image according to the received signal and transfers the image to the liquid crystal glasses, and finally the observer can dynamically observe the images in different visual fields through the rotation of the head.

Description

The dynamic visual angle liquid crystal glasses

Technical field

The utility model relates to a kind of liquid crystal glasses of watching video image, refers to a kind of can the rotation and the dynamic liquid crystal glasses of adjusting the observation visual angle with human body head especially.

Background technology

Along with the development of liquid crystal glasses technology, add and carry light and advantage such as 3D viewing effect that its application in the multimedia field is increasingly extensive; The deficiency that liquid crystal glasses exists at present shows as: as a kind of new-type head-mounted display apparatus, liquid crystal glasses is the same with old-fashioned fixed display devices, no matter the visual field of its shown picture 2D or 3D all is changeless at present, can not change along with the angular turn of human body head; This defective has greatly limited user's the visual field, also makes 3D effect not enough to some extent.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and providing a kind of can rotate and the dynamic liquid crystal glasses of adjusting the observation visual angle with human body head.

For achieving the above object, the technical solution adopted in the utility model is: built-in three inertial sensors, utilize its attitude measurement function, and the rotational orientation of human body head is passed to video frequency terminal apparatus; Video frequency terminal apparatus is adjusted image according to the signal that receives, and image is passed to liquid crystal glasses, finally makes the beholder dynamically watch image in the different visuals field by head rotation.

Described three inertial sensors are the microminiature gyroscope, are a kind of x, and y, z three-axis attitude survey sensor, the attitude information of measurement can be one or more of angular acceleration, angular velocity, angle;

Described microminiature gyroscope places the top of head hoop; Signal wire and power lead are drawn from lower end; Signal wire directly is connected with the video frequency terminal apparatus port or connects by interface convertor;

Described video frequency terminal apparatus is computing machine or game host.

The utility model function novelty cooperates 3D recreation or 3D image, can observe the content of different visual angles by the rotation of head, compared with prior art, has enlarged user's the visual field, has improved 3D effect greatly.

Description of drawings

Fig. 1 is the utility model overall appearance synoptic diagram.

The figure number explanation:

1 microminiature gyroscope, 2 head hoops, 3 liquid crystal glasses, 4 microminiature gyroscope signal lines, 5 microminiature gyroscope power leads, 6 coupling spindles.

As shown in Figure 1, liquid crystal glasses 3 is the evaluation equipment of multimedia video in the present embodiment, can be by the image of signal wire or blue tooth wireless communication receiver, video terminal device;Head hoop 2 is connected with liquid crystal glasses 3 by coupling spindle 6, and the effect of coupling spindle 6 is to rotatehead hoop 2.

Among Fig. 1, microminiature gyroscope 1 is positioned at the top ofhead hoop 2, in microminiaturegyroscope signal line 4 and the microminiaturegyroscope power lead 5 built-inhead hoops 2, draws in the bottom, and links to each other with video frequency terminal apparatus (computing machine or game host), power supply respectively.

Embodiment

Lift a typical example that adopts the dynamic visual angle liquid crystal glasses below:

Current computer 3D plays and changes user's visual angle by mouse, and the presence of user in recreation is not strong.In this example, liquid crystal glasses 3 is connected by blue tooth wireless communication with main frame, operation 3D recreation on the main frame; When user's head rotation, microminiature gyroscope 1 records the rotational angle of head and signal is passed to main frame by microminiaturegyroscope signal line 4; Main frame receives behind the signal according to angle value, changes the 3D scene of game and passes to liquid crystal glasses 3 by blue tooth wireless communication, thereby reach the purpose that the user dynamically watches image, has strengthened 3D effect.

Liquid crystal glasses 3 also can pass through wired connection with main frame in this example.
