keyboard.vr.touchTyping (off by default): a key is pressed when a controller's tip, where SteamVR's laser starts (/pose/tip: the device pose times the render model's "tip" component), passes through it from the front; released when pulled back 1 cm, re-armed 5 mm in front. Both hands, also at once. Keys go through the keyboard's own HandleTouchStart / HandleTouchEnd, like a laser press (Backspace repeats while held). Options depth (cm) and haptics. The geometry lives in a reusable controller bridge (vr-keyboard-controllers, internal option): a systemui patch reads the keyboard's pose with SteamVR's SGQueryService (an empty transform of ours in the keyboard's mount) and both controllers' poses, and streams per hand the tip, the laser's hit on the keyboard and the trigger (~90 Hz while relevant) through the vr-keyboard-controllers-relay service to __sfuiControllers in Steam's SharedJSContext. Tests: flake checks vr-keyboard-controllers and vr-keyboard-touch.

# Touch typing on Steam's VR keyboard (steamFrame.keyboard.vr.touchTyping): a
|
|
# key is pressed when a controller's tip (where SteamVR's laser starts)
|
|
# passes through it. Independent of keyboard.vr.enable / extraKeys.
|
|
# - The tips relative to the keyboard come from the controller bridge
|
|
# (vr-keyboard-controllers.nix, turned on here).
|
|
# - vr-keyboard-touch/keyboard-patch.js (Steam UI, 8080; patch
|
|
# "vr-keyboard-touch"): tracker.js per hand (contact, hysteresis); presses
|
|
# the key with the keyboard's own touch handlers, like a laser press.
|
|
# Tests: vr-keyboard-touch/check.nix (built before the patch; also flake
|
|
# check `vr-keyboard-touch`).
