“…Visual cues coded in the egocentric frame of reference indicate the position of target objects relative to the viewer's body axes. Such self-centered cues, like arrows [24,26,39,43,44,52,53,56] or tunnels [4,45,46,49], guide the user's attention directly to the target object without the need to understand the surrounding environment. Also classical guidance techniques, such as Halos [2], Wedges [20], CityLights [62], EdgeSplit [25] or EdgeRadar [21] for applications on desktop and wearables belong to the egocentric dimension for simple locate tasks, since the cues are displayed relative to the user's field of view.…”
