“…In Eye-SeeThrough, head movement controls a toolglass that can be moved over gaze-fixated targets [29]. Other work has supplemented eye pointing with subsequent refinement of the selection by head movement [18,19,22,49]. Recently,Pinpointing compared head versus eyes as primary pointing modes, and a variety of techniques for subsequent selection refinement [23].…”

Eye gaze involves the coordination of eye and head movement to acquire gaze targets, but existing approaches to gaze pointing are based on eye-tracking in abstraction from head motion. We propose to leverage the synergetic movement of eye and head, and identify design principles for Eye&Head gaze interaction. We introduce three novel techniques that build on the distinction of head-supported versus eyes-only gaze, to enable dynamic coupling of gaze and pointer, hover interaction, visual exploration around pre-selections, and iterative and fast confirmation of targets. We demonstrate Eye&Head interaction on applications in virtual reality, and evaluate our techniques against baselines in pointing and confirmation studies. Our results show that Eye&Head techniques enable novel gaze behaviours that provide users with more control and flexibility in fast gaze pointing and selection.

“…are now both integrated in commodity headsets for virtual reality (VR). There are mainly two reasons for this: (1) substantial processing-power in headsets may be saved using gaze-contingent rendering where the full image is only shown at the current fixation point [Murphy and Duchowski 2001;Reingold et al 2003], and (2) gaze may serve as a hands-free pointer for effortless interaction with head-mounted displays (HMD) [Jalaliniya et al 2015]. Dwell selection has become the preferred selection method for "eyes only" input.…”

Gaze and head tracking, or pointing, in head-mounted displays enables new input modalities for point-select tasks. We conducted a Fitts' law experiment with 41 subjects comparing head pointing and gaze pointing using a 300 ms dwell (n = 22) or click (n = 19) activation, with mouse input providing a baseline for both conditions. Gaze and head pointing were equally fast but slower than the mouse; dwell activation was faster than click activation. Throughput was highest for the mouse (3.24 bits/s), followed by head pointing (2.47 bits/s) and gaze pointing (2.13 bits/s). Dwell activation was faster than click activation. The effective target width for gaze (≈ 94 pixels; about 3 •) was larger than for head and mouse (≈ 72 pixels; about 2.5 •). Subjective feedback rated the physical workload less for gaze pointing than head pointing.

“…In our technique, we use eye tracking data in combination with the information obtained from additional sensors for target selection. Others have also utilized the additional tracking sensors available on commercial head-mounted displays for enhancing 3D gaze estimation [21,23,26].…”
