Radar recognition-aided search
This document describes techniques and devices for a radar recognition-aided search. Through use of a radar-based recognition system, gestures made by, and physiological information about, persons can be determined. In the case of physiological information, the techniques can use this information to refine a search. For example, if a person requests a search for a coffee shop, the techniques may refine the search to coffee shops in the direction that the person is walking. In the case of a gesture, the techniques may refine or base a search solely on the gesture. Thus, a search for information about a store, car, or tree can be made responsive to a gesture pointing at the store, car, or tree with or without explicit entry of a search query.
1. A computer-implemented method, the method implemented on a device and comprising:
receiving, by the device, a search request having a search query;
recognizing, by the device, an in-the-air gesture that has multiple potential meanings and is received through a radar-based recognition system, the recognizing based on reflections of a radar field received by an antenna of the radar-based recognition system;
determining, by the device, a meaning about the in-the-air gesture that is relevant to the search request from the multiple potential meanings, the determining based on a comparison of the multiple potential meanings associated with the in-the-air gesture in combination with the search request;
causing, by the device, a search to be performed, the search based on the received search query and refined using the determined meaning of the in-the-air gesture; and
providing, by the device, search results responsive to the search request.
2. The computer-implemented method as described in claim 1 , wherein receiving the search request having the search query receives the search request through an input of the device, determining the meaning about the in-the-air gesture that is relevant to the search request determines a geographic direction and providing the search results provides the search results in the form of locations on a map, a list of terms or webpages, or a media presentation.
3. The computer-implemented method as described in claim 2 , wherein receiving the search request receives the search request through an audio communication system and determining the meaning about the in-the-air gesture that is relevant to the search request is responsive to and based on the in-the-air gesture being recognized commensurate with receiving the search request through the audio communication system.
4. The computer-implemented method as described in claim 2 , wherein the geographic direction indicates a street and refining the search refines the search to be performed searching street addresses.
5. The computer-implemented method as described in claim 2 , wherein the geographic direction indicates a building and refining the search refines the search to be performed searching addresses within the building.
6. The computer-implemented method as described in claim 1 , wherein determining the meaning about the in-the-air gesture that is relevant to the search request determines an intended path and providing the search results provides search results along the intended path.
7. The computer-implemented method as described in claim 1 , wherein the determined meaning about the in-the-air gesture that is relevant to the search request is used to refine a prior search.
8. The computer-implemented method as described in claim 1 , wherein determining the meaning about the in-the-air gesture that is relevant to the search request determines an object to which the in-the-air gesture is directed.
9. The computer-implemented method as described in claim 8 , wherein the object is presented as part of a media presentation and further comprising determining information about the object.
10. A computer-implemented method, the method implemented on a device and comprising:
receiving, by the device, first reflections of a radar field through an antenna of a radar-based recognition system, the first reflections corresponding to a first in-the-air gesture and recognized by the radar-based recognition system as an indication that a user of the device is requesting a search;
receiving, by the device, second reflections of the radar field through the antenna of the radar-based recognition system, the second reflections corresponding to a second in-the-air gesture;
determining, by the device, information about the second in-the-air gesture sufficient to refine the search, the determining based on a comparison of potential meanings associated with the second in-the-air gesture;
performing, by the device, or causing performance of by another device, the search, the search refined in accordance with the determined information about the second in-the-air gesture; and
providing, by the device, search results resulting from performing the search.
11. The computer-implemented method as described in claim 10 , wherein determining the information about the second in-the-air gesture determines that the second in-the-air gesture is a geographical direction.
12. A computer-implemented method, the method implemented on a device and comprising:
receiving, by the device and through an input of the device, a search request having a search query;
determining, by the device based on reflections of a radar field received through an antenna of a radar-based recognition system of the device, physiological information about a person associated with the device, the physiological information including at least one of a heart rate, a hydration level, a body temperature, or a stress level of the person;
performing, by the device, or causing performance of by another device, the requested search using a combination of the search query and the determined physiological information about the person; and
providing, by the device, the search results resulting from performing the requested search using the combination of the search query and the determined physiological information.
13. The computer-implemented method as described in claim 1 , further comprising emitting the radar field from the device.
14. The computer-implemented method as described in claim 12 , wherein the radar-based recognition system differentiates human tissue from non-human objects.
15. The computer-implemented method as described in claim 12 , further comprising transmitting the determined physiological information to another device.
16. The computer-implemented method as described in claim 1 , wherein receiving the search request includes receiving the search request based on a touch-input to a touchscreen.
17. The computer-implemented method as described in claim 10 , further comprising prompting the user for additional information prior to performing the search.
18. The computer-implemented method as described in claim 10 , wherein the determined information indicates a control input for the device.
