Method, device and equipment for realizing space trajectory input

Abstract

The invention provides a method, a device and equipment for realizing space trajectory input. The method comprises the following steps: acquiring gyroscope data and acceleration sensor data of wearable equipment under a three-axis coordinate system; based on a preset unit quaternion and the gyroscope data, converting the acceleration sensor data into acceleration sensor data under a space coordinate system; based on acceleration sensor data in a space coordinate system before the current sampling moment, determining space coordinates of the wearable device at the current sampling moment; converting the space coordinate into a coordinate in a camera coordinate system and zooming to obtain a screen two-dimensional coordinate of the wearable device at the current sampling moment; based on the screen two-dimensional coordinate, triggering a screen Touch event to display a coordinate point at the current sampling moment; and based on the continuously displayed coordinate points, obtaining a screen trajectory corresponding to the spatial trajectory of the wearable device to complete input of the spatial trajectory. According to the method, the information input operation of the wearable equipment is simple and convenient and is not interfered by the environment, and the privacy is ensured.

Description

technical field [0001] This application relates to the technical field of wearable devices, in particular to a technology for realizing spatial trajectory input. Background technique [0002] With the continuous development of science and technology, wearable devices are increasingly favored and relied on by people, and interaction through wearable devices has become a daily need. Existing wearable devices support a variety of information input methods, including: 9-key soft keyboard input, handwriting input, voice input, etc. But as wearable devices get miniaturized, their screens are smaller. [0003] Among the information input methods supported by existing wearable devices, for 9-key soft keyboard input and handwriting input, it is very inconvenient to operate with fingers on the small screen of the wearable device; for voice input, it is easily disturbed by the external environment, and in public The occasion is not high in privacy.
