Viewing distance requires large characters to ensure legibility on TV-set

Published: 29 August 2017 Publication History

Abstract

The use of interactive services on the television set (TV-set) remains low. This may come from user interfaces (UIs) that are poorly suited to the context of use, in particular the distance of use of the TV-set. To verify this, 1,054 users representative of French households with both Internet access and TV-set are asked to make measurements to determine this distance of use. The results of the survey show that the distance of TV-set use makes it impossible or difficult to read present UIs dedicated to the TV-set. Knowledge on reading in cognitive science, presented in ISO 9241-303: 2011, enables to verify that the character sizes used are too small. These results question the "10-foot user interface" commonly used for the TV-set. This involves rethinking the UIs, and maybe even reconsidering the interactive services generally offered on the TV-set.
