People with low vision experience accessibility barriers when they interact with the web. This paper explores the navigation strategies of low vision users in order to select the appropriate accessibility techniques to design web interfaces for them. For this purpose, an exploratory study was carried out with six users with low vision. The results revealed the heterogeneity in the group of people with low vision and the variety of navigation strategies applied. Observations and analysis of data gathered in experimental sessions allowed a set of techniques to be defined that can improve accessibility for people with low vision when interacting with the web.
