Wrist rotation menu interaction technology based on LeapMotion sensor

Abstract

The invention relates to the technical field of interaction, in particular to a wrist rotation menu interaction technology based on a LeapMotion sensor. The method comprises the following steps: firstly, acquiring real-time rotation data of a wrist through a LeapMotion sensor; secondly, reflecting the rotation angle to traversal of menu items; and finally, selecting a currently traversed menu item by stretching out a finger type. The method is combined with the current mature sensor technology, is easy to assemble and carry, enhances the expansion capability of the menu on the basis of invariable direct touch conditions, can realize continuous interaction greatly even without movement in some interaction scenes, increases the degree of freedom of touch interaction, the interaction efficiency is improved for the man-machine interaction task, the interaction expressive force is enhanced, and the interaction interestingness is increased.

Description

technical field [0001] The invention relates to the field of interaction technology, in particular to a wrist rotation menu interaction technology based on a LeapMotion sensor. Background technique [0002] In the traditional graphical user interface, the mouse is the most popular pointing device. It can perform a series of pointing tasks only by changing the two-dimensional coordinate position on the interface, and it provides more convenience for users. Moreover, the powerful menu technology greatly expands the interactive content and interactive capabilities between the user and the interactive device, and improves the interactive efficiency. [0003] In recent years, with the sharp increase in the use of touch-screen devices, touch-based operations have become an ingrained way of interaction in daily life. This more intuitive and direct interaction feature is better than traditional physical devices in some cases ( such as mouse, keyboard, etc.). [0004] However, most...

[0004] However, most touch devices limit the user's operation to a certain degree of freedom. The methods we usually use, such as pressing, releasing, and sliding, do achieve and enrich the functions that traditional devices can achieve to some extent.

However, in many application scenarios in life, touch interaction with limited degrees of freedom is still not enough to fully express the user's complex operation behavior and intention, especially in some specific interaction scenarios (such as painting tasks, etc.), we do not want to need to frequently This discrete interaction mode realizes the selection of different interactive functions by moving different distances
