Finger-type wearable device and human-computer interaction method

Abstract

The present invention provides a finger-type wearable device and a human-computer interaction method. A pressure touch sensor and an inertial measurement unit are used to detect the position, intensity and sliding direction data of the finger on the surface of the device, as well as to detect the linear acceleration and angular rate change data, so that the finger displacement, rotation, percussion, a specific gesture and other movement are converted into a computer input instruction; the device is worn on the index finger, the surface of the pressure touch sensor is pressed by using the thumbto achieve the control instruction input, and operating in the two-dimensional environment, the switching time of the hand between the keyboard and the mouse in use of the calculation to complete theroutine tasks can be greatly reduced; a 6-freedom-degree inertia measurement unit and the pressure touch sensor are set, the interaction between people and computers and the 3D devices can be greatlyenriched; and at the same time, the cooperation operations of multiple rings can achieve more abundant gestures and functions, and infinite possibilities are provided for interaction in 2D and 3D scenes.

Description

technical field [0001] The invention relates to the technical field of human-computer interaction, in particular to a ring-like wearable device and a method for human-computer interaction. Background technique [0002] At present, desktop computers, tablet computers, 2D and 3D smart TVs, virtual reality devices (Virtual Reality), and even large-scale visual platforms such as CAVE Automatic Virtual Environment (CAVE Automatic Virtual Environment) and other smart devices and application scenarios that require interaction continue to increase. The interaction mode of smart devices has gradually expanded from the traditional 2D requirements to the interaction requirements in the 3D environment. [0003] In a typical application scenario of 2D interaction, computers are becoming more and more important in people's work and life, and people spend more and more time in front of computers. The traditional mouse is one of the two indispensable input devices, and its invention is of ...

AI Technical Summary

Problems solved by technology

For decades, the mouse has basically not improved. It can only move monotonously on a two-dimensional plane, which seriously endangers the health of the wrist and makes people more and more unbearable.

In 3D interactive application scenarios, such as 3D games, 3D video editing, 3D graphic design, etc., traditional and developing 3D interactive devices, such as 3D mouse (3Dconnexion Space Navigator), image gesture recognition based on Kinect, Leap Motion's Infrared gesture recognition and Wiimote game controllers, etc., can achieve certain interactive purposes in specific application scenarios, but generally have many defects such as single application scenarios, slow recognition speed, and prone to errors.

For example, gesture recognition based on camera or infrared sensor, the recognition speed is slow, and it cannot be recognized well when the hand is blocked by an object or itself

Therefore, as the field of 2D interaction shifts from a single desktop computer to a richer and more diverse plane, traditional mouse-type interactive devices have great limitations when applied in these scenarios, and cannot meet current and future development needs.

In the case of a surge in demand for 3D interaction, there is still a lack of a portable, accurate and stable interactive device suitable for scene applications
