A method of virtual interaction

Abstract

The invention discloses a virtual-interaction method. The method is applied between an active body and a passive body, and includes: respectively modeling the active body and the passive body to obtain a first model of the active body and a second model of the passive body, wherein the first model includes a line segment main-body model and a ball cap model connected with each other, and the second model includes a curved-surface model; determining an interaction state between the first model and the second model, wherein the interaction state is determined by a distance between the first model and the second model, and interaction states include a proximity state, a contact state and a squeeze state; and calculating a change of the first model or calculating a change of the second model according to the interaction state. The technical solution provided by the invention can improve the precision of human-machine interaction.

Description

technical field [0001] The invention relates to the technical field of human-computer interaction, in particular to a virtual interaction method. Background technique [0002] Currently, in human-computer interaction, information input methods adopted by users usually include the following types: [0003] 1. Traditional physical interaction, that is, input is completed through real physical devices, such as widely used mice, keyboards, gamepads, remote controls, etc. The disadvantages of this method are: the size of the physical interaction is too large to be used for micro-devices; the function is very restrictive and can only solve the input requirements of one device (for example, the mouse cannot be used on mobile phones); the fixed size of the device cannot adapt to different groups of people. (People with larger hands feel that the keyboard spacing is small, while people with small hands feel the opposite). [0004] 2. Wearable entity interaction, that is, complete i...

Problems solved by technology

The disadvantages of this method are: the size of the physical interaction is too large to be used for micro-devices; the function is very restrictive and can only solve the input requirements of one device (for example, the mouse cannot be used on mobile phones); the fixed size of the device cannot adapt to different groups of people. (People with larger hands feel that the keyboard spacing is small, while people with small hands feel the opposite)

The disadvantage of this method is: it must be worn to interact; it can only recognize simple movements of the worn part

The disadvantages of this method are: the interaction range is limited by the size of the device; the hand blocks the interface during interaction

The disadvantage of this method is that the hand cannot interact on the support surface, otherwise the support surface will be misjudged as a hand and make an error

The disadvantages of this method are: the support surface must be flat (not uneven); the recognition accuracy is low, and it is easy to touch by mistake; it is impossible to recognize the strength of the finger pressing the surface
