Video game | Falling blocks iPad game |
Holmes et al.25 Manh et al.26 Gao et al.30 |
Game where points are scored by moving falling blocks to form complete lines of blocks | Red-green anaglyphic glasses; high-contrast elements seen by the amblyopic eye and reduced-contrast by the fellow eye |
Dig rush iPad game |
Kelly et al.27 Holmes et al.28 Holes et al.29 |
Action adventure game with miners digging for gold | ||
Video viewing | Dichoptic movie |
Birch et al.31
Sauvan et al.35 |
Movies shown on a passive 3D display | Glasses with polarized lenses; a patterned image mask made of irregularly shaped blobs is applied to the images seen by the amblyopic eye (high contrast) and the inverse mask is applied to the images seen by the fellow eye (reduced contrast) |
Dichoptic movie with interactive tasks | Bossi et al.32 | Movies shown on a 3D capable computer monitor and interrupted by interactive tasks to measure suppression | Shutter glasses mounted in a customized ski mask; image presented to the non-amblyopic eye blurred | |
BinoVision home system | Mezad-Koursh et al.33 | Video or movie shown on head-mounted goggles; customizable content | Contrast and brightness levels reduced for the non-amblyopic eye; superimposed moving objects and momentary repetitive bright video frame stimuli shown only to the amblyopic eye | |
Luminopia One | Xiao et al.34 | Video shown via a smartphone on a head-mounted display; streaming of wide variety of licensed content | Contrast levels reduced for the non-amblyopic eye; dichoptic masks superimposed so that parts of the video are only visible to the amblyopic eye | |
Virtual reality (VR) | Interactive Binocular Treatment (I-BiT) system37 |
Waddingham et al.38 Cleary et al.39 Rajavi et al.40 Herbison et al.41 |
Interactive games and movies on a 3D VR based computer system | Red-green filter or shutter glasses; enriched image presented to the amblyopic eye; for games, key elements only visible to the amblyopic eye |
Diplopia game in Oculus Rift OC DK2 | Žiak et al.42 | Games played in a 3D setting in a VR head mounted display connected to a computer | Dichoptic setting in which the central part of the picture is shown differently to each eye; images from both eyes needed to successfully play the games |
