Augmented Reality applications use explicit cuing to support visual search. Explicit cues can help improve visual search performance but they can also cause perceptual issues such as attentional tunneling. An experiment was conducted to evaluate the relationship between directing attention and attentional tunneling, in a dual task structure. One task was tracking a target in motion and the other was detection of non-target elements. Three conditions were tested: baseline without cuing the target, cuing the target with the average scene color, and using a red cue. A different color for the cue was used to vary the attentional tunneling level. The results show that directing attention induced attentional tunneling only the in red condition and that effect is attributable to the color used for the cue.
