I’m tracing the pre-VR lineage of head-coupled perspective for a spatial computing interaction audit and I’m curious which shipped title did it first. Johnny Lee’s Wii demo (2007) popularized the trick, TrackIR hit flight sims by 2003, and 3DS face-tracking stabilized stereo in 2015, but what’s the earliest mainstream release that bound parallax to head pose out of the box?
“the earliest mainstream release that bound parallax to head pose out of the box?” I’d point to Nintendo’s DSiWare Rittai Kakushi e Attakoreda (Looksley’s Line Up, 2009) using the DSi camera for off-axis head‑coupled perspective: https://en.wikipedia.org/wiki/Looksley’s_Line_Up. From experience, keep bright frontal lighting or the face lock jitters. Does handheld DSiWare clear your ‘mainstream’ bar, or are you after TV console titles?
