Chronicle

• On 30 September 2026, the project was initialized with design specs and a Vite and TypeScript scaffold including vec3 helpers.^[1][2]
• On 30 September 2026, device configuration was established with presets and auto-guessing, alongside screen-space conversion math and iris-based eye estimation.^[3][4][5]
• On 30 September 2026, geometric projection was extended with billboard projection, matrix3d homography, and perspective point projection.^[6][7]
• On 30 September 2026, eye tracking gained one-euro smoothing, monotonic detector timestamps, MediaPipe asset fetching, camera access, and face tracking, with fixes for camera stream shutdown and error classification.^[8][9][10]
• On 30 September 2026, interaction UI was built out with a demo page using mouse-driven correction, camera tracking pipeline with inset and fullscreen modes, tuning panel for presets and smoothing, and face-lost hold and ease blending.^{[11][12][13][14][15][16][17][18]}
• On 30 September 2026, the demo's camera and mouse mode toggle was restored and camera start logic, error detection, phone layout, and field-of-view calculations were addressed in final review.^[19]
• On 30 September 2026, the headline feature was added to keep apparent size constant with viewing distance and a Following/Static toggle was implemented.^[20][21]
• On 30 September 2026, scene rendering was documented with targets scene design and implementation specs, and box and ring-target geometry was added.^[22][23][24]
• On 30 September 2026, field-of-view calibration math was implemented alongside a per-preset calibration store and one-click calibration dialog.^[25][26][27]
• On 30 September 2026, an SVG scene renderer was added with top bar and scene markup, and a Targets/Text scene switch was created to make the targets scene the default.^[28][29]
• On 30 September 2026, calibration was fixed to cancel and reset when mode switches or other interruptions occur, and scene rendering was corrected to emit box grid segments once and sort stick and disc painting.^{[30][31][32][33]}
• On 30 September 2026, calibration was fixed to collect up to 3 seconds when frames are slow, ignore reopens mid-run, and discard results for changed devices, and SVG visibility writes were optimized.^[34][35][36]
• On 1 October 2026, Line of Sight game design and implementation specs were documented.^[37][38]
• On 1 October 2026, depth smoothing at the iris and per-frame view easing were added across multiple systems.^[39]
• On 1 October 2026, Line of Sight game shapes and level table were defined, and levels were built along rays from the solution eye.^[40][41]
• On 1 October 2026, the Line of Sight session state machine was implemented with a fix for non-finite frame gaps.^[42][43]
• On 1 October 2026, the Line of Sight renderer, HUD, and grid-only backdrop were added, and Line of Sight was integrated as a third scene with its own game loop.^[44][45]
• On 1 October 2026, game pieces were fixed to remain hidden until the first render after level setup, and the Star solution eye was moved away from the bottom of the webcam frame.^[46][47]
• On 1 October 2026, mouse-mode eye distance was locked to the solution distance in the game, and misalignment was recomputed after auto-advance to prevent stale first frames.^[48][49]
