AI Technical Summary

Benefits of technology

This technology helps people who write on their screens by giving them an indication that they're sitting up straight for hours without getting tired from bending over too much at once. It also prevents eye strain caused by incorrect positioning during long periods of time.

Problems solved by technology

Technological Problem: Current methods aim at reducing egoive power (E) without addressing specific issues such as nearsightness caused by hypermetropism or presbytropic crystals. However, these techniques may be limited because their effectiveness depends heavily upon factors like environmental conditions during training sessions.

Embodiment 1

[0032] Such as figure 1 As shown, this embodiment includes a power supply module, a head posture measurement module, an infrared distance measurement module, a data collection and processing module, an alarm module, and a wireless communication module. In this embodiment, the power supply module, head posture measurement module, infrared distance measurement module, data acquisition and processing module, alarm module, and wireless communication module are all packaged in wearable items on the human head, such as headbands, headbands, and hair clips.

[0033] Specifically, the head posture measurement sensor in the head posture measurement module adopts the ADXL345 acceleration sensor, which is used to measure the wearer's head posture, including measuring the acceleration signal magnitudes of three orthogonal axes.

[0034] Further, the infrared ranging sensor in the infrared ranging module adopts Sharp GP2D12, and the sensor conditioning circuit is used to filter and amplify...

Embodiment 2

[0041] Such as figure 2As shown, this embodiment includes a power supply module, a head posture measurement module, an infrared distance measurement module, a data collection and processing module, an alarm module, and a wireless communication module. In this embodiment, the power supply module, head posture measurement module, infrared distance measurement module, data acquisition and processing module, alarm module, and wireless communication module are all packaged in wearable items on the human head, such as headbands, headbands, hairpins, etc. In actual use, the device is worn in the middle of the forehead. The difference from Embodiment 1 is that in this embodiment, an MCU, ARM or SoC chip with a wireless function is used to replace the data acquisition and processing module and the wireless communication module in Embodiment 1, thereby reducing equipment cost and volume. In this embodiment, an Intel Curie chip with a Bluetooth 4.0 wireless communication module is used...

Embodiment 3

[0043] Such as image 3 As shown, this embodiment includes a power supply module, a head posture measurement module, an infrared distance measurement module, a data collection and processing module, an alarm module, and a wireless communication module. In this embodiment, the power supply module, head posture measurement module, infrared distance measurement module, data acquisition and processing module, alarm module, and wireless communication module are all packaged in wearable items on the human head, such as headbands, headbands, and hair clips.

[0044] The difference from Embodiment 1 is that the head posture measurement sensor in the head posture measurement module in this embodiment uses a BMA150 gravity sensor for measuring the wearer's head posture.

[0045] Further, this embodiment also includes a matching smart terminal, the wireless communication module performs wireless communication with an external smart terminal installed with an application program APP, and ...

Abstract

The invention discloses a myopia-prevention type wearable device. The wearable device is worn at the forehead part of the head of a user. The device internally comprises a power supply module, a head posture measurement module, an infrared distance measurement module, a data acquisition and processing module, an alarm module and a wireless communication module. The power supply module is respectively connected with the head posture measurement module, the infrared distance measurement module, the data acquisition and processing module, the alarm module and the wireless communication module so as to power on the above modules. The data acquisition and processing module is respectively connected with the head posture measurement module, the infrared distance measurement module, the alarm module and the wireless communication module. According to the technical scheme of the invention, an alarm is sent to a wearer to remind the wearer when the wearer gets too close to a writing desktop or a reading object. Therefore, the myopia prevention is achieved. Meanwhile, whether the wearer is just lowering his/her head to read or write or not can be effectively judged. As a result, no wrong alarm prompt is sent out.
