Head-mounted augmented reality (AR) devices can provide assistance, by recoding difficult-to-perceive information into a visual format that is more accessible. Here, we evaluate symbolic and alphanumeric information representations for their efficiency and usability in two prototypical AR applications: namely, recognizing facial expressions of conversational partners and reading the time. We find that while AR provides a general benefit, the complexity of the visual representations has to be matched to the user\u2019s visual acuity.<\/jats:p>","DOI":"10.1007\/978-3-030-58796-3_19","type":"book-chapter","created":{"date-parts":[[2020,9,10]],"date-time":"2020-09-10T12:02:54Z","timestamp":1599739374000},"page":"146-156","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Augmented Reality for People with Low Vision: Symbolic and Alphanumeric Representation of Information"],"prefix":"10.1007","author":[{"given":"Florian","family":"Lang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Albrecht","family":"Schmidt","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tonja","family":"Machulla","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2020,9,4]]},"reference":[{"key":"19_CR1","series-title":"Lecture Notes on Data Engineering and Communications Technologies","doi-asserted-by":"publisher","first-page":"244","DOI":"10.1007\/978-3-030-03146-6_26","volume-title":"International Conference on Intelligent Data Communication Technologies and Internet of Things (ICICI) 2018","author":"A Ashok","year":"2019","unstructured":"Ashok, A., John, J.: Facial expression recognition system for visually impaired.
