COMMUNICATION USING BIOPOTENTIAL SENSING AND TACTILE ACTIONS
Among other things, a received inbound message is presented to a person wearing a wearable device. The inbound message is presented to the person as tactile stimulation of skin of the person. Monitoring is done for presence of an outbound message derived from biopotential signals sensed at the skin of the person after the receipt of the inbound message.
1 . A method comprising
receiving an inbound message to be presented to a person wearing a wearable device,
presenting the inbound message to the person as tactile stimulation at the wearable device of skin of the person, and
monitoring for presence of an outbound message derived from biopotential signals sensed at the skin of the person after the receipt of the inbound message.
2 . The method of claim 1 in which the inbound message comprises a status request.
3 . The method of claim 2 in which the status request comprises a poll.
4 . The method of claim 1 in which the presenting of the inbound message comprises vibrating the skin of the person.
5 . The method of claim 1 comprising decoding the inbound message as a corresponding profile of tactile stimulation of skin, and in which the presenting comprises presenting the profile of tactile stimulation.
6 . The method of claim 1 in which presence of an outbound message within a predetermined response period after the receipt of the inbound message comprises a reply to the inbound message.
7 . The method of claim 1 in which lack of presence of an outbound message within a predetermined response period after the receipt of the inbound message comprises a reply to the inbound message.
8 . The method of claim 1 in which the monitoring for presence of an outbound message derived from biopotential signals comprises sensing biopotential signals indicative of an intention by the person wearing the wearable device to reply to the inbound message.
9 . The method of claim 8 comprising encoding the sensed biopotential signals as the outbound message.
10 . The method of claim 1 comprising sending the outbound message to another participant.
11 . The method of claim 1 in which the biopotential signals are sensed at by the wearable device.
12 . The method of claim 1 in which the wearable device is situated at a wrist of the person.
13 . The method of claim 1 in which the receiving of the inbound message comprises receiving the inbound message wirelessly from another device.
14 . The method of claim 1 comprising receiving a series of inbound messages at the wearable device, the inbound messages comprising polls.
15 . A method comprising
sending an inbound message to be presented as tactile stimulation of skin of a person wearing a wearable device, and
monitoring for presence of an outbound message derived from biopotential signals sensed at the skin of the person after the sending of the inbound message.
16 . The method of claim 15 in which the inbound message comprises a status request.
17 . The method of claim 16 in which the status request comprises a poll.
18 . The method of claim 15 comprising interpreting presence of an outbound message within a predetermined response period after the sending of the inbound message as a reply to the inbound message.
19 . The method of claim 15 comprising interpreting lack of presence of an outbound message within a predetermined response period after the sending of the inbound message as a reply to the inbound message.
20 . The method of claim 15 in which sending the outbound message comprises sending the inbound message wirelessly from another device.
21 . The method of claim 15 comprising sending a series of output messages comprising polls.
22 . An apparatus comprising
a wearable device comprising
a support configured to hold the wearable device on a body part of a user,
a wireless transmitter,
a wireless receiver,
a tactile element configured to be in contact with skin of a user,
a biopotential sensor configured to be in contact with skin of the user,
storage for executable instructions, and
a processor to execute the instructions to cause
the wireless receiver to receive an inbound message,
the tactile element to convey the inbound message to the user through the skin of the user,
the biopotential sensor to sense biopotential signals at the skin of the user within a predetermined amount of time after the inbound messages conveyed to the user through the skin of the user, and
the transmitter to send an outbound message comprising the biopotential signals or biopotential information derived from the biopotential signals.
