Such a versatile device, although tested at the experimental laboratory demonstrator stage, has never been integrated in a compact and portable way in a real environment. In this context, we built a low-cost, light-weight, head-mounted device integrating a miniature camera and a laser pointer that can be remotely controlled or servo-controlled by an eye tracker. Two motorizations were implemented and tested (pan\/tilt and Rilsey-prisms-based). The video was both recorded locally and transmitted wirelessly. Risley prisms allowed finer remote control of camera or laser pointer orientation (0.1\u00b0 vs. 0.35\u00b0), but data processing and Wi-Fi transmission incur significant latency (~0.5 s) limiting the servo-controlling by eye movements. The laser beam was spatially shaped by a Diffractive Optical Element to facilitate object illumination or recognition. With this first proof-of-concept prototype, the data stream needs to be optimized to make full use of the eye tracker, but this versatile device can find various applications in education, healthcare or research.<\/jats:p>","DOI":"10.3390\/s23073503","type":"journal-article","created":{"date-parts":[[2023,3,28]],"date-time":"2023-03-28T01:41:34Z","timestamp":1679967694000},"page":"3503","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Head-Mounted Miniature Motorized Camera and Laser Pointer Driven by Eye Movements"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1949-2207","authenticated-orcid":false,"given":"Vincent","family":"Nourrit","sequence":"first","affiliation":[{"name":"Optics Department, IMT Atlantique, 29238 Brest CEDEX 03, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean-Baptiste","family":"Lamour","sequence":"additional","affiliation":[{"name":"Eyes Triple Shut, 78430 Louveciennes, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bernard","family":"Abiven","sequence":"additional","affiliation":[{"name":"Optics Department, IMT Atlantique, 29238 Brest CEDEX 03, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2032-0031","authenticated-orcid":false,"given":"Bruno","family":"Fracasso","sequence":"additional","affiliation":[{"name":"Optics Department, IMT Atlantique, 29238 Brest CEDEX 03, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean-Louis","family":"de Bougrenet de la Tocnaye","sequence":"additional","affiliation":[{"name":"Optics Department, IMT Atlantique, 29238 Brest CEDEX 03, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"713","DOI":"10.1364\/JOSA.52.000713","article-title":"Head-mounted eye-marker camera","volume":"52","author":"Mackworth","year":"1962","journal-title":"J.
