Introduction: This is a rehabilitation wheelchair for a variety of paralyzed and disabled people to use at home. It uses safe and comfortable non-invasive BCI equipment, combined with certain AR technology, so that patients can express or complete their daily life needs through simple eye movements or body movement imagination, and carry out simple illusion sports training, as well as entertainment activities such as games, audio and video.
The interactive mode of the device is mainly visual stimulation that can be mastered without training. The sudden stimulation mode of P300 is cross-integrated with the continuous steady-state stabbing of SSVEP, which effectively avoids the possibility of unconscious operation by the user; at the same time, the SMR motion illusion The application of potential also enriches the interactive extensibility of the device. Users can unlock more interactive games after certain game-based training, including game-based muscle recovery training.
Regarding the equipment modeling, I analyzed and referred to a variety of different wheelchair types, extracted structural lines, combined with brain-computer interface technology and the necessary wired connection of the target population, comfortable and less noise, etc. Interactive behavior feedback adopts more intuitive AR visual feedback, giving more plastic and free color to what the paralyzed people see and hear. The appearance design of the AR device caters to the data output requirements of the brain-computer interface, covering a large area of the occipital lobe and a few overhead areas, reducing the assembly time of a single use of the device without affecting the wearing comfort, and optimizing the assembly experience of the caregiver. The product name -- MRIn, which is taken from the marionette and translated as a marionette, is derived from the association of complex electrode lines for brain-computer equipment. It should not be a colorless day after day, even if it is bound freedom.
