[0039] figure 1is a block diagram showing an example of the system configuration of the mobile body control device according to the first embodiment of the present invention. The mobile body control device 10 according to the first embodiment controls the driving of a mobile body (such as an electric wheelchair) 11 that moves with a user riding thereon. The mobile body control device 10 includes an electroencephalograph 1 , a teacher signal generation unit 2 , a brain signal separation unit 3 , a control signal generation unit 4 , a drive control unit 5 and a visual feedback unit 6 .

[0040] Note that the mobile body control device 10 is configured with a microcomputer as a center. A microcomputer includes CPU (Central Processing Unit), ROM (Read Only Memory) and RAM (Random Access Memory) as the main hardware components. , RAM temporarily stores processing data, etc. Brain signal separation unit 3 , control signal generation unit 4 , drive control unit 5 , visual feedback...

[0067] Figure 5 is a block diagram showing an example of the system configuration of the mobile body control device according to the second embodiment of the present invention. The mobile body control device 20 according to the second embodiment includes a myoelectric potential detection unit 21 and a stop determination unit 22 in addition to the components of the mobile body control device 10 according to the first embodiment.

[0068]The myopotential detection unit 21 includes one or more myopotential sensors, such as dry surface electrodes, wet surface electrodes, or silver / silver chloride plate electrodes. A myoelectric sensor attached to the cheek or neck area, etc. can be moved instantaneously by the user. This can easily and reliably detect the user's myoelectric potential. Each myoelectric sensor of the myoelectric potential detection unit 21 outputs the detected myoelectric potential to the stop determination unit 22 as a myoelectric potential signal.

[0074] Image 6 is a block diagram showing an example of a system configuration of a mobile body control device according to a third embodiment of the present invention. In the mobile body control device 30 according to the third embodiment, the control signal generation unit 34 includes a signal generation unit 34a and a signal selection unit 34b, and the signal generation unit 34a is based on the calculated characteristic value fp and the relationship between the characteristic value fp and the control signal. The corresponding relation of the corresponding relationship continuously generates the control signal corresponding to the feature value fp, and the signal selection unit 34b divides the control signals continuously generated by the signal generation unit 34a into groups, and each group has a predetermined number (for example, three) of Continuous control signals, and for each group, select the type of control signal with the largest number in each group.

Abstract

A mobile body control device includes a brain activity detecting unit for detecting information about the brain activity of the user, a brain signal separating unit for separating the artifact component from the detected information about the brain activity, a control signal generating unit for staggering by predetermined periods the sampling periods during which the brain data is extracted from the information about the brain activity excluding the artifact component while overlapping the sampling periods with each other, calculating a feature value of the brain data detected during the staggered sampling periods, and generating a control signal according to the calculated feature value, and a driving / controlling unit for driving / controlling the mobile body in / on which the user rides according to the generated control signal.

Description

technical field [0001] The present invention relates to a mobile body control device and a mobile body control method for controlling a mobile body traveling together with a user riding on it. Specifically, the present invention relates to a mobile body control device and a mobile body control method for driving and controlling a mobile body based on user's brain activity information. Background technique [0002] In recent years, various control methods have been proposed as methods for operating a mobile body by utilizing brain activity information of a user. Controls using this brain activity information, for example, have the advantage of providing a rapid, user-friendly interface (or an interface that can also be used by physically disabled people). It is difficult to obtain such advantages with conventional controls, such as control using myoelectric potential and control using an operating system such as a joystick. [0003] Meanwhile, there is known an activity sup...
