Multi-channel human-computer interaction ergonomics evaluation system and evaluation method for holographic display

Abstract

The invention relates to a holographic-display-oriented multichannel man-machine interaction work efficiency evaluation system and evaluation method. The system is composed of a holographic projection system, a multichannel interaction system, and a physiological signal acquisition and processing system. The holographic projection system includes a projector and a 180-degree holographic cabinet; the projector is arranged in front of the 180-degree holographic cabinet directly and is used for irradiating the 180-degree holographic cabinet. According to the invention, the system has high extensibility and can be provided with other input devices to complete testing and evaluation various interaction work efficiencies under holographic display; and for example, the system can be applied to multichannel multi-interaction work efficiency researches in environments like an aviation cockpit or a car cabin. In addition, the provided evaluation method is simple and can be implemented conveniently and rapidly; interaction can be carried out by selecting a multi-channel condition or a mouse interaction condition correspondingly according to an evaluation result, thereby reducing unnecessary fatigue on cognition of an interactive user. Therefore, the method and system have the great practical application significance.

Description

technical field [0001] The invention belongs to the technical field of ergonomics and relates to an experiment system, in particular to a holographic display-oriented multi-channel human-computer interaction ergonomics evaluation system and evaluation method. Background technique [0002] Hologram technology, also known as virtual imaging technology, is a technology that uses the principles of interference and diffraction to record and reproduce the real three-dimensional image of an object. The complete implementation of this technology consumes a huge amount of calculations, and the conditions of use are harsh, and it has not yet reached the requirements of practical applications in the near future. For example, the research team of Savas Tay, a professor at Univ.of Arizona in the United States, has studied the use of digital holographic printing methods on photorefractive-polymer, a new holographic recording material, to record a 4in×4in digital hologram in a relatively s...

Problems solved by technology

Ergonomics in multi-channel human-computer interaction has always been a major direction of human-computer interaction. As the display method of multi-channel human-computer interaction changes from computer screen to holographic display, ergonomics has once again become an urgent research issue

Brain load is an important indicator of ergonomics, but the existing technology cannot realize the judgment of the brain load of the interactor under the holographic display, and the evaluation of ergonomics
