Since the physical and electromagnetic aspects of the sensors' operation can significantly affect the analysis and use of their data, it is essential for those who rely on these data to understand these details. As such, the authors provide a simplified and yet technically precise explanation of some of the sensors found on the Motorola Droid, which are representative of sensors found in most smartphones. The authors specifically explain its proximity sensor, Hall effect magnetometer, capacitive accelerometer, orientation sensor, and light sensor. Each sensor is described using illustrations and experiments that are provided to demonstrate some unexpected behaviors.<\/p>","DOI":"10.4018\/jhcr.2013040105","type":"journal-article","created":{"date-parts":[[2013,8,9]],"date-time":"2013-08-09T20:01:00Z","timestamp":1376078460000},"page":"69-80","source":"Crossref","is-referenced-by-count":2,"title":["An Overview of the Capabilities and Limitations of Smartphone Sensors"],"prefix":"10.4018","volume":"4","author":[{"given":"Avi","family":"Klausner","sequence":"first","affiliation":[{"name":"Department of Electrical and Computer Engineering, Boston University, Boston, MA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ari","family":"Trachtenberg","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Boston University, Boston, MA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Starobinski","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Boston University, Boston, MA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark","family":"Horenstein","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Boston University, Boston, MA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2432","reference":[{"key":"jhcr.2013040105-0","unstructured":"Android Developers.
