When SteamVR crashes, safe mode can block the newest add-on, and then it
skips the ft_pointer driver at every start. The cursor still moves (the
pointer helper draws it), but clicks, scrolling and mapped actions go
through the driver's virtual controller, so none of them do anything,
and nothing said why (#4).
Input Settings now shows a warning at the top of every page with the
fix: Manage Add-Ons in SteamVR's settings, unblock ft_pointer, restart
SteamVR. It reads steamvr.vrsettings (~/.config/openvr/config on the
Frame) for blocked_by_safe_mode, a disabled driver, or SteamVR's own
safe mode. When none of those is set but SteamVR is running (the helper
answers) and @ft_pointer doesn't, it says SteamVR runs without the
driver: unblocked but not restarted yet, or not installed. The driver
ignores the "ping" it sends. It checks at startup and every 30 minutes,
since the driver only changes when SteamVR restarts.

A controller released the 3D mouse's pointer on a single pose sample
faster than 0.35 m/s or 2 rad/s, once the mouse had been still for
500 ms. The helper polls about every 8 ms, so one noisy sample was
enough: a knock on the desk, or a tracking jump when the headset's
cameras pick a resting controller up again (#1).
A controller now has to stay over the limit for 100 ms in a row, and
only samples with a normal tracking result (Running_OK) count. The new
POINTER_CONTROLLER_PICKUP setting (1 by default, 0.5 to 5) scales both
limits; it's a slider on the Pointer page of Frametop Input Settings
and applies live. A controller picked up for real still gets the laser
back through SteamVR's hand role, which follows its touch sensors. The
release log now records the speed and spin that triggered it, to tune
the default.

The Frame controllers aren't input devices on the host, so the pointer
helper reads them with SteamVR input (vrbuttons.h, actions/), one action
set per button, and sends presses to the relay, which does the mapped
action like for a mouse button. Only mapped buttons are taken, at an
overlay-global priority (SteamVR's experimental "Enable global input from
overlays"), and only outside games unless In games is on. Frametop Input
Settings gets a Controllers page to map them.
Gaze mode: a left press while the gaze has the pointer isn't sent at
once. The pointer stops, you drag it onto what you meant with the button
held, and the release clicks there; a press held still for
POINTER_GAZE_HOLD (0.5 s) becomes a real press, for drags. The dot shows
only while the mouse moves it (POINTER_GAZE_SHOW), while a press is held,
and as a pulse per click. Outside games the pointer stays on while gaze
mode is on. ft-gazed takes a third of each lesson's offset instead of all
of it: in the first live test one 6 degree lesson moved everything and put
the next target 7 degrees off. Frametop Input Settings gets a Gaze page.

MAGIC pointing (Zhai et al. 1999), off by default: with POINTER_GAZE=1,
"gaze on", or a button mapped to the new gaze_toggle action, the cursor ray
is the corrected gaze from ft-gazed while the gaze has the pointer. Moving
the mouse takes the pointer from where the gaze left it; looking more than
POINTER_GAZE_RETAKE (5 deg) away with the mouse still gives it back. The
pointer is aimed at the gaze, never steered toward it, and only fresh gaze
moves it, so a stopped service or a blink leaves it where it is. A mouse
nudge of up to POINTER_GAZE_NUDGE_MAX (8 deg) before a click is sent to
ft-gazed as a lesson in the eye tracker's error.

It works but is only lightly tested, and what's left is mostly tuning its
settings. Frametop Input Settings now says so under the Head follow switch,
and the README, design notes, and button action name say it too.

Easing the reference toward the head all the time moved the cursor on
every small head movement, so a cursor parked in a corner of the view
drifted. Now nothing moves while the head stays within the leash. Once
the head has been past it for POINTER_LEASH_DELAY (0.2 s, so a glance
out and back doesn't count), the reference eases all the way to where
you face (POINTER_LEASH_RETURN) and the cursor lands back in its place
in the view, then the leash waits again. Leaning inside the leash no
longer moves the cursor either. Leash 0 stays head-locked.

The leash only moved its reference when the head reached the leash's end,
so after turning back it sat up to the leash off, and recentring meant
overshooting with the head. The reference now eases toward the head's
facing (POINTER_LEASH_RETURN, 0.2 s) and never lags more than the leash,
so the cursor settles back to its place in the view once the head stops.
The mouse can now move the cursor up to POINTER_FOLLOW_REACH (70 degrees)
from the middle of the view, up from a fixed 40. Both are sliders on the
Pointer page.

Off by default. With POINTER_FOLLOW=1 (a switch on the Pointer page of
Frametop Input Settings, or a mouse button mapped to Head follow on/off),
the cursor rides on a reference direction leashed POINTER_LEASH_DEG (10)
from where you face. Within the leash it stays put in the room; past it,
it turns with your head and keeps its offset. A leash of 0 locks it to
your view. Head roll is ignored, the cursor stays within 40 degrees of
the reference, and it holds still in the room while the left button is
down so the head can't nudge a click or a drag.

Several KDE Plasma screens floating in SteamVR, each a real monitor of any
resolution and shape, shown by our own compositor (ft-screens), with a
layout, wrist pinning, and visibility modes; a Bluetooth mouse that drives
all of SteamVR as a room-anchored 3D pointer (input relay, ft-pointer
helper, ft_pointer SteamVR driver); two settings apps; and Bluetooth LE
fixes. Installs on the headset with ./install.sh.
