Problems solved by technology

[0008] (1) First of all, Cardboard only magnifies the display of the mobile phone, and it does not have any sensors
Secondly, Cardboard is only fixed to the user's head by a Velcro, which is easy to cause shaking and not very comfortable to wear.
[0009] (2) Since the weight of the Oculus DK2 is not light and the weight is mainly distributed on the face, the user is likely to cause discomfort during use
And Oculus DK2 cannot detect physiological parameters, and cannot grasp the user's psychological and physical feelings

Embodiment 1

[0034] The headband for virtual reality glasses provided in the present invention, the headband includes a headband structure and a headband circuit, and is characterized in that: the headband structure includes: an annular protective pad, a long strap arranged horizontally, Short straps set horizontally, vertical straps set vertically; headband circuit includes: EEG signal test electrodes, temperature and humidity module, vibration module, PPG sensor, pressure sensor, lithium battery, main controller, processing circuit and Bluetooth module.

[0035] Such as figure 1 As shown, the headband circuit includes the following: 1.1 is the EEG signal test electrode 1, 1.2 is the EEG signal test electrode 2, 1.3 is the EEG signal test electrode 3, 1.4 is the EEG signal test electrode 4, and 1.5 is the EEG signal test electrode 1. Signal test electrode 5, 1.6 is EEG signal test electrode 6, 1.7 is EEG signal test electrode 7, 1.8 is EEG signal test electrode 8, 1.9 is EEG signal test ...

Embodiment 2

[0044] The microcontroller uses the STM32 processor, model STM32F103RBT6, introduced by ST (Standard Microelectronics). This type of processor is 32-bit RSIC (reduced instruction set), Cortex-M3ARM core, 72Mhz operating frequency, high-speed embedded memory (Flash memory reaches 128Kbytes, SRAM reaches 20Kbytes), there are multiple enhanced I / Os and interfaces connected to Two APB buses. This family provides two 12-bit ADCs, three general-purpose 16-bit timers and a PWM timer. This series also has rich interfaces: 2 I2C and SPI, 3 serial ports, a USB and CAN bus.

[0045] The EEG signal testing electrode is a needle electrode, wherein the length of the microneedle is between 20-100 μm, which can not only penetrate the stratum corneum to obtain effective EEG signals, but also effectively prevent the scalp from being damaged. According to the characteristics of the EEG signal, the amplifier with high input impedance, high common mode rejection ratio and low noise is selected, ...

Abstract

The invention provides a headband for virtual reality glasses, comprising a headband structure and a headband circuit, the headband structure comprising: a circular protective pad, a long strap arranged horizontally, and a short strap arranged horizontally 1. A vertical strap arranged vertically; the headband circuit includes: an EEG signal test electrode, a temperature and humidity module, a vibration module, a PPG sensor, a pressure sensor, a lithium battery, a main controller, a processing circuit and a Bluetooth module. The headband of the virtual reality glasses of the present invention has a simple structure, and can accurately detect physiological parameters such as electroencephalogram signals, body temperature, blood oxygen concentration, pulse and pressure on the bridge of the nose.

Description

technical field [0001] The invention relates to virtual reality technology and wearable computing technology, and more specifically, to a headband for virtual reality glasses. Background technique [0002] Virtual reality technology (Virtual Reality, referred to as VR) can simulate the user's sense of hearing, touch, vision and other senses, allowing users to observe the three-dimensional virtual space simulated by computing equipment in an all-round and unlimited manner, as if they were in the real world. territory. In recent years, with the rapid development of various technologies related to virtual reality technology, various products related to virtual reality emerge in endlessly. [0003] Virtual reality glasses are wearable products for visual entertainment based on virtual reality, which close people's vision and hearing to the outside world, guide users to have a feeling of being in a virtual environment, and allow users to observe the three-dimensional space in a ...
