Abstract
A brain computer interface (BCI) module includes a flexible printed circuit assembly (FPCA) configured to conform to the head of a user. A plurality of emitters and a plurality of detectors are mounted on the FPCA. Each emitter of the plurality is configured to emit light towards the head of the user and each detector is configured to detect the emitted light. An array of ferrules is additionally mounted to the FPCA such that each ferrule of the array encases an emitter or a detector. The BCI module additionally includes a controller that is configured to receive an optical signal detected by a detector of the plurality and to encode the detected signal into a biological signal.
Claims20
A brain-computer interface (BCI) module for enabling a user to interface a computing device, the BCI module comprising:
- a flexible printed circuit assembly (FPCA) configured to conform to a head of a user, the FPCA having a first surface and a second surface opposite to the first surface;
- a plurality of emitters mounted on the first surface of the FPCA, each emitter configured to emit light towards the head of the user;
- a plurality of detector mounted on the FPCA, each detector configured to detect light reflected from the head of the user;
- an array of ferrules mounted on the FPCA, the plurality of ferrules comprising a first set of ferrules and a second set of ferrules, each ferrule of the first set of ferrules encasing an emitter and each ferrule of the second set of ferrules encasing a detector, each ferrule of the first set of ferrules comprising a ferrule body disposed on the first surface of the FPCA;
- and
- a controller coupled to the plurality of emitters and the plurality of detectors, the controller configured to:
- receive an optical signal detected by a detector of the plurality of detectors;
- encode the detected optical signal;
- and
- transmit the encoded optical signal to the computing device.
A head-mounted display (HMD) comprising:
- at least one brain-computer interface (BCI) module for enabling a user to interface a computing device, the BCI module comprising:
- a flexible printed circuit board (FPCA) configured to conform to a head of a user, the FPCA having a first surface and a second surface opposite to the first surface;
- a plurality of emitters mounted on the first surface of the FPCA, each emitter configured to emit light towards the head of the user;
- a plurality of detector mounted on the FPCA, each detector configured to detect light reflected from the head of the user;
- an array of ferrules mounted on the FPCA, the plurality of ferrules comprising a first set of ferrules and a second set of ferrules, each ferrule of the first set of ferrules encasing an emitter and each ferrule of the second set of ferrules encasing a detector, each ferrule of the first set of ferrules comprising a ferrule body disposed on the first surface of the FPCA;
- and
- a controller coupled to the plurality of emitters and the plurality of detectors, the controller configured to:
- receive an optical signal detected by a detector of the plurality of detectors;
- encode the detected optical signal;
- and
- transmit the encoded optical signal to the computing device.
