These functions determine how much virtual movements are amplified compared to the corresponding physical movements. However, it is unclear how the design of these functions influences the user\u2019s gait and experience when walking with high\u00a0gain values. In a mixed-methods study with 20 users, we find that their best transfer functions are nonlinear and asymmetrical for starting and stopping. We use an optimization approach to determine individually optimized functions that are significantly better than a common approach of using a constant gain. Based on interviews, we also discuss what qualities of walking matter to users and how these vary across different functions. Our work shows that it is possible to create high-gain walking techniques that offer dramatically increased range of motion and speed but still feel like normal walking.<\/jats:p>","DOI":"10.1007\/s10055-022-00692-w","type":"journal-article","created":{"date-parts":[[2022,9,9]],"date-time":"2022-09-09T18:28:53Z","timestamp":1662748133000},"page":"777-795","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Step on it: asymmetric gain functions improve starting and stopping in virtual reality walking"],"prefix":"10.1007","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7827-3760","authenticated-orcid":false,"given":"Thomas","family":"van Gemert","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kasper","family":"Hornb\u00e6k","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joanna","family":"Bergstr\u00f6m","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2022,9,9]]},"reference":[{"key":"692_CR1","doi-asserted-by":"publisher","unstructured":"Abtahi P, Gonzalez-Franco M, Ofek E, Steed A (2019) I\u2019m a Giant: Walking in Large Virtual Environments at High Speed Gains.
