Emotional/cognitive state presentation is described. When two or more users, each using a device configured to present emotional/cognitive state data, are in proximity to one another, each device communicates an emotional/cognitive state of the user of the device to another device. Upon receiving data indicating an emotional/cognitive state of another user, an indication of the emotional/cognitive state of the user is presented.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A method comprising: detecting, at a first device associated with a first user, a second device associated with a second user; determining, by the first device, an emotional or cognitive state of the first user; at least partly in response to detecting the trusted relationship, communicating to the second device, an indication of the emotional or cognitive state of the first user. 2. A method as recited in claim 1, wherein detecting the second device associated with the second user comprises detecting that the second device is in proximity to the first device. 3. A method as recited in claim 1, wherein detecting the second device associated with the second user comprises determining that a trusted relationship exists between the first user and the second user. 4. A method as recited in claim 1, wherein determining the emotional or cognitive state of the first user comprises receiving biometric sensor data indicating the emotional or cognitive state of the first user. 5. A method as recited in claim 1, further comprising: receiving from the second device, data identifying an emotional or cognitive state of the second user; presenting an indicator of the emotional or cognitive state of the second user. 6. A method as recited in claim 5, wherein presenting the indicator of the emotional or cognitive state of the second user includes presenting a virtual indicator within a virtual reality environment or mixed reality environment visible to the first user. 7. A method as recited in claim 6, wherein the virtual indicator includes a colored aura associated with the second user or a representation of the second user. 8. A system comprising: a device proximity detection module associated with a first device configured to detect a second device in proximity to the first device, wherein the first device is associated with a first user and the second device is associated with a second user; a sensor data analysis module associated with the first device, the sensor data analysis module configured to determine an emotional or cognitive state of the first user based at least in part on sensor data representing a physiological condition of the first user; and a communication interface configured to send, from the first device to the second device, data indicating the emotional or cognitive state of the first user. 9. A system as recited in claim 8, wherein the communication interface is further configured to receive at the first device, from the second device, data indicating an emotional or cognitive state of the second user. 10. A system as recited in claim 9, further comprising a presentation interface, wherein the presentation interface is configured to present the data indicating the emotional or cognitive state of the second user. 11. A system as recited in claim 10, wherein the presentation interface comprises a display device configured to display an augmented reality view. 12. A system as recited in claim 8, further comprises a biometric sensor to capture the sensor data. 13. A system as recited in claim 8, wherein the analysis module is implemented as a digital neural network (DNN) chip. 14. A system as recited in claim 8, implemented as a head-mounted display device. 15. One or more computer readable media having computer-executable instructions stored thereon, which, when executed by a first computing device, cause the first computing device to perform operations comprising: detecting a second computing device in proximity to the first computing device, wherein the first computing device is associated with a first user and the second computing device is associated with a second user; determining, based on sensor data, an emotional or cognitive state of the first user; and transmitting from the first computing device to the second device, data indicating the emotional or cognitive state of the first user. 16. One or more computer readable media as recited in claim 15, wherein detecting a second computing device in proximity to the first computing device further comprises determining a trusted relationship between the first user and the second user. 17. One or more computer readable media as recited in claim 15, the operations further comprising: receiving at the first computing device, from the second computing device, data indicating an emotional or cognitive state of the second user; presenting, for the first user, an indication of the emotional or cognitive state of the second user. 18. One or more computer readable media as recited in claim 17, wherein the indication of the emotional or cognitive state of the second user comprises a visual indication within an augmented reality view. 19. One or more computer readable media as recited in claim 15, the operations further comprising capturing the sensor data using a biometric sensor. 20. One or more computer readable media as recited in claim 15, implemented as a component of a head-mounted display device.
