However, widespread use of RFIDs as sensors requires significant instrumentation to deploy tethered readers, which limits usability in mobile settings. Our solution is WearID, a low-power wrist-worn backscatter reader that bridges this gap and allows ubiquitous sensing of interaction with tagged objects. Our end-to-end design includes innovations in hardware architecture to reduce power consumption and deal with wrist attenuation and blockage, as well as signal processing architecture to reliably detect grasping, touching, and other hand-based interactions. We show via exhaustive characterization that WearID is roughly 6\u00d7 more power efficient than state-of-art commercial readers, provides 3D coverage of 30 to 50 cm around the wrist despite body blockage, and can be used to reliably detect hand-based interactions. We also open source the design of WearID with the hope that this can enable a range of new and unexplored applications of wearables.<\/jats:p>","DOI":"10.1145\/3375800","type":"journal-article","created":{"date-parts":[[2020,4,9]],"date-time":"2020-04-09T07:35:06Z","timestamp":1586417706000},"page":"1-22","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":6,"title":["Continuous Measurement of Interactions with the Physical World with a Wrist-Worn Backscatter Reader"],"prefix":"10.1145","volume":"1","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7373-6655","authenticated-orcid":false,"given":"Ali","family":"Kiaghadi","sequence":"first","affiliation":[{"name":"University of Massachusetts Amherst, Amherst, MA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pan","family":"Hu","sequence":"additional","affiliation":[{"name":"Stanford University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeremy","family":"Gummeson","sequence":"additional","affiliation":[{"name":"University of Massachusetts Amherst, Amherst, MA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Soha","family":"Rostaminia","sequence":"additional","affiliation":[{"name":"University of Massachusetts Amherst, Amherst, MA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Deepak","family":"Ganesan","sequence":"additional","affiliation":[{"name":"University of Massachusetts Amherst, Amherst, MA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2020,4,9]]},"reference":[{"key":"e_1_2_1_1_1","volume-title":"Retrieved","author":"Avery Dennison Corp.","year":"2019","unstructured":"Avery Dennison Corp. 2019 .
