Human-computer interaction and identity authentication device and method suitable for virtual reality equipment

Abstract

The invention provides a human-computer interaction method. The human-computer interaction method comprises the following steps of: (1), detecting key points of eyes including upper and lower eyelids, inner circles and outer circles of irises and pupil centres, fitting to obtain position information of boundaries of the upper and lower eyelids, canthus and boundaries of the inner circles and outer circles of the irises, and obtaining accurate pupils and iris centres through information of the inner circles and outer circles of the irises; (2), calculating the direction of eyeball sight, and, in combination with the position of the sight correspondingly on a display screen of virtual reality equipment, completing eyeball sight tracking; (3), performing stare / blink detection of eyeballs including stare detection and blink detection, if stare / blink detection is passed, entering the step (4), and otherwise, entering the step (5); (4), executing corresponding operations for specific stare items in stare detection, and then, returning to the step (1) to perform detection of the key points of the eyes; and (5), according to the eyeball sight direction, updating a display content of the virtual reality equipment, and then, returning to the step (1) to perform detection of the key points of the eyes.

Description

technical field [0001] The present invention relates to the field of virtual reality technology, human-computer interaction and identity authentication, in particular to a device for human-computer interaction and identity authentication of virtual reality equipment using the characteristics of the iris of the human eye, and also relates to the human-computer interaction and identity authentication based on the device. authentication method. Background technique [0002] With the rapid development of virtual reality technology and wearable technology, head-mounted virtual reality devices have created a new consumer electronics market and will be popularized rapidly in the foreseeable future. For example, eBay took the lead in launching the first virtual reality department store based on head-mounted virtual reality equipment. [0003] However, the human-computer interaction and identity authentication method based on the head-mounted virtual reality device has defects. Duri...

Problems solved by technology

[0003] However, the human-computer interaction and identity authentication method based on the head-mounted virtual reality device has defects. In the payment process, the user needs to take off the head-mounted virtual reality device and perform identity authentication in the eBay-related application of the mobile device to complete the transaction.

Repeated removal of virtual reality glasses equipment not only greatly weakens the user's immersive experience, but also indirectly increases the complexity of identity authentication
