“…Standard input methods are dwell-time activation, (i.e., looking at a target for a set time, for instance 500 ms, e.g., Ware & Mikaelian, 1987); stroke activation (i.e., looking in one or several directions, in a consecutive order, with a saccade in between, e.g., Drewes & Schmidt, 2007); and pursuit activation (i.e., following a smoothly moving target area, e.g., Vidal, Bulling, & Gellersen, 2013). Current gazeinteraction research focuses on challenges and potentials in smart-phone interaction (e.g., Rozado, Moreno, Agustin, Rodriguez, & Varona, 2015), smart-watches (e.g., Hansen et al, 2016), ubiquitous displays (e.g., Velloso, Wirth, Weichel, Esteves, & Gellersen, 2016) and head-mounted displays (e.g., Itoh & Klinker, 2014).…”
