Ultrasonic-based holographic image interactive display method, control method and system

Abstract

The invention discloses a hologram image interaction type display method based on ultrasonic wave, a control method and a system, and solves a problem in the prior art that an operation only can be carried out on a screen plane. The interaction type display method comprises the following steps: controlling an ultrasonic wave detection device to scan a three-dimensional space to determine a target object; and then, determining a first position of the target object and a second position of the target object in a display area to display a visual image corresponding to the target object. The control method comprises the following steps: controlling the ultrasonic wave detection device to scan the three-dimensional space to determine the gesture operation of the target object, determining the gesture, and executing a control operation corresponding to a gesture. The device comprises an ultrasonic wave detection unit, a position determining unit and a display control unit, wherein the ultrasonic wave detection unit is used for determining the target object, the position determining unit is used for determining the first position of the target object, and the display control unit is used for controlling a display area to display the visual image. On the basis of the gesture operation carried out in the three-dimensional space by a user in front of a screen, a three-dimensional interaction operation is realized.

Description

technical field [0001] The present invention relates to the field of user application technology, in particular to an ultrasonic-based holographic image interactive display method, control method and system. Background technique [0002] User Interface (UI) design refers to the overall design of human-computer interaction, operation logic, and beautiful interface of software. In the process of human and machine interaction to obtain information and experience, there is a medium, that is, a visualized human-computer interaction interface, and an interactive device and method corresponding to the human-computer interaction interface. For example, the emergence of touch-screen mobile phones has brought the touch interaction method to the vast consumer public. At the same time, the interactive interface of the traditional mouse and keyboard has rapidly turned to the interactive interface adapted to the touch interaction mode. Users can click or drag icons displayed on the scre...

Problems solved by technology

[0003] However, in the existing touch screen, whether it is a capacitive touch screen or a resistive touch screen, a piece of touch glass or film will be added in front of the liquid crystal display (LCD) panel, thus increasing the thickness and weight of the display screen.

At the same time, when consumers touch the display screen with their fingers to control the electronic device, it is easy to cause the device itself to shake, and there is a certain distance and angle between the display screen and the consumer.

In addition, direct touch control of the display screen with fingers may easily lead to the problem of fingerprints remaining on the display screen

Furthermore, the richness of the content in the flat interactive interface operated by touch is relatively limited, and the confirmation selection is performed by moving the cursor to a certain button and staying for a period of time. This operation can only perform a confirmation or entry operation , the richness of interaction is limited, and the user feels unnatural enough, and feels constrained when interacting
