Abstract
Systems and methods for position-based gesture control are described. In some embodiments, a system may include a wearable device including a biopotential sensor and a location sensor. The system may be configured to determine that a body part is in a first position relative to a person's body, detect a first gesture, and, in response, direct a first instruction to a first destination. The system may be further configured to determine that a body part is in a second position relative to the person's body, detect a second gesture, and, in response, direct a second instruction to a second destination different than the first destination.
Core Innovation
The invention relates to responding to an intention expressed by a person using a wearable device that includes a biopotential sensor and a location sensor. The biopotential sensor outputs data indicating biopotentials at a body part associated with controlling one or more appendages of the person, and the location sensor outputs data indicating a location of the body part. The system determines that the body part is in a first position relative to the body at a first time and, while the body part is in the first position, detects a first gesture representative of a first intention based on the biopototential sensor output.
The system further determines that the body part is in a second position relative to the body of the person at a second time, where the second position is different than the first position. While the body part is in the second position, the system detects a second gesture representative of a second intention based on the biopotential sensor output. In response to detecting the gesture while the body part is in the corresponding position, the system directs different instructions to different destinations.
The destinations differ between the first position and the second position, and the first instruction and the second instruction are directed to different destinations based, at least in part, on the first gesture and the second gesture being detected while the body part is in different positions relative to the body. The architecture includes determining body-part position from location sensor output, detecting gestures from biopotential output, and mapping detected gestures and positions to instructions for applications or external machines.
Claims Coverage
The document includes two independent claims. Across them, the coverage is centered on detecting gestures from biopotential sensor output while a body part is in different positions determined from location sensor output, and directing different instructions to different destinations based on both the gestures and the body-part positions.
Wearable biopotential and location-based intention response with position-dependent gesture and different destinations
A system for responding to an intention expressed by a person with a wearable device including a biopotential sensor outputting biopotentials at a body part associated with controlling one or more appendages, a location sensor outputting a location of the body part, and a processor configured to determine a first position at a first time and, while the body part is in the first position, detect a first gesture representative of a first intention based on the biopotential sensor output and direct a first instruction to a first destination; determine a second position at a second time different from the first position and, while the body part is in the second position, detect a second gesture representative of a second intention based on the biopotential sensor output and direct a second instruction to a second destination, where the first destination differs from the second destination and the first and second instructions are directed to different destinations based, at least in part, on the first gesture and second gesture being detected while the body part is in different positions.
Method using position-determined biopotential gesture intention response with different instructions to different destinations
A method performed using a system comprising a wearable device, comprising determining that a body part is in a first position relative to a body at a first time based on output from a location sensor indicating location of the body part; while the body part is in the first position, detecting a first gesture representative of a first intention based on output from a biopotential sensor indicating biopotentials at the body part; in response to detecting the first gesture while the body part is in the first position, directing a first instruction to a first destination; determining that the body part is in a second position relative to the body at a second time, where the second position differs from the first position; while the body part is in the second position, detecting a second gesture representative of a second intention based on the output from the biopotential sensor; and in response to detecting the second gesture while the body part is in the second position, directing a second instruction to a second destination, wherein the first destination differs from the second destination and the first and second instructions are directed to different destinations based, at least in part, on the first and second gestures being detected while the body part is in different positions relative to the body.
Both independent claims require coupling gesture detection from biopotential sensor output with body-part position determination from a location sensor, and directing different instructions to different destinations depending on both the detected gestures and the positions in which those gestures are detected.
