Scroll Operation

Initially, the scroll function is off. Let's try scrolling once you get used to the operations. To change the settings, click the Scroll Method button on the main screen.

Types of Scrolling

Illustration Display: No Scroll Slow Medium Fast

Type	Overview	Scroll Up	Scroll Down
Tilt Scroll	Scrolling at 3 different speeds is activated according to the angle when in command waiting mode. - Sequential Correction: Corrects the tilt over several tens of seconds. Be aware that if you keep it tilted, it will be corrected to that position as the front. - No Correction: Scrolls according to the tilt of the device itself. Scrolling will be activated if the device is tilted, even if the glasses are straight.
Slow Tilt Left/Right	- Slowly tilt the ASSIST for a period of time (default is about 0.4 seconds, can be changed) and then stop to start scrolling. - It reacts to the duration of the continuous angle change, not the absolute value of the angle, so please move slowly. - When scrolling has started, changing the angle further in the same direction will increase the speed by one step (up to 3 steps). - When scrolling has started, moving in the opposite direction will stop scrolling.
Slow Tilt Forward/Backward	- The forward/backward version of the above.
Tilt Twice in the Same Direction Left/Right	- Tilt twice in the same direction without returning to the original position (tilt → stop → tilt → stop) to start scrolling. - Reacts with the same sensitivity as commands. - When scrolling has started, changing the angle further in the same direction will increase the speed by one step (up to 3 steps). - When scrolling has started, moving in the opposite direction will stop scrolling.
Tilt Twice in the Same Direction Forward/Backward	- The forward/backward version of the above.
Shortcut	Assign a scroll shortcut in the settings to perform a short scroll once.
Disabled	Does not scroll.

Changing Scroll Direction macOS

The default OS setting on a Mac has the scroll direction reversed compared to other OSs. To fix this, please refer to FAQ (Scrolling is reversed on Mac, iPad).

Operation Status Display

• JINS ASSIST indicates its current mode and status through the remote control display, LED lighting pattern, and tray icon.
• The tray icon is displayed in the tray (Windows)/menu bar (Mac).
• To ensure visibility, the colors of the LED lighting pattern and tray icon are partially different.

Status (Remote Display)	LED Device	Tray Icon Auxiliary Software
Command Waiting (Stopped)	Green, 3-second pulse
Cursor Moving	Blue, 0.5-second pulse
Click Selecting	Orange, solid
Dragging	Blue, 0.2-second pulse
Continuous Flow Judging	Orange, 0.2-second pulse
Scrolling	Light Blue, 0.5-second pulse

Other Modes

• In addition to Normal Mode (nod, move cursor, select and click, or auto-click), there are the following modes.
• To switch modes, set the Mode Switch Command / Pause On/Off in the shortcut call function, or click the mode display/switch button on the remote control.
• Modes marked with Special Mode are automatically applied in abnormal situations.

Status (Remote Display)	Description	LED Device	Tray Icon Auxiliary Software
Cursor Always Synced	A mode where head movement and cursor movement are always synced. Clicking is not possible, so use another device to click or set the OS to click on dwell.	Dark Pink, solid
Paused (Commands Disabled)	Stops responding to nods, and cursor movement and clicking become impossible (only accepts the Pause (Commands Disabled) On/Off shortcut).	Red, solid
Noise Stop Special Mode	Automatically stops when trying to put on the glasses, when JINS ASSIST is subjected to an impact, etc., and returns to the previous mode after 2 seconds.	Red, solid
Startup (Waiting for Upright) Special Mode	Enters waiting for upright mode when JINS ASSIST is not upright immediately after startup. Automatically switches to the previously used mode when made upright.	Red, 2-second pulse
Disconnected	Not connected to a PC.	Off

Sensor Correction Device

If the cursor moves at a constant speed, it will be corrected by holding your head still for about 1 second (it will not be corrected if strong breathing or heartbeat transmits vibrations). The correction may be off when you sharply move your head down or up, so in that case, please hold still and correct in line with your head's angle.

Shortcuts Device

• You can perform quick operations by assigning frequently used operations in Settings -> Shortcut Settings.
• To call a shortcut, shake your head in the specified direction and number of times as shown in the video below.
• Shortcuts work in Command Waiting (Stopped), Cursor Moving, and Cursor Always Synced modes.
• In Paused (Commands Disabled) mode, only Pause (Commands Disabled) On/Off will respond.

Status Change	Action Pattern
Startup	The cursor rotates three times in a small circle to signal that startup is complete.
Nod Detection Waiting	In normal mode, moving your head moves it slightly up, down, left, or right in that direction. A nod is detected when a down → up movement is detected in succession.
Scrolling	When a scroll command is detected, it moves slightly up or down.
Mode Switch	When switching from normal mode using the mode switch in "Shortcut Call" or Pause (Commands Disabled) On/Off, the cursor rotates three times in a small circle to signal that the switch is complete.

Main Screen (Remote Display) Auxiliary Software

The remote is displayed first when the auxiliary software is launched.

Main Screen (Settings Display) Auxiliary Software

You can change the settings from the ⚙️(Settings) button in the auxiliary app.

Basic Settings

Setting Item	Details
Command to reset cursor position	With the turned-on operation, you can return the cursor position to the center of the screen. When "3 Esc key presses" is set, all Esc key events are received by this app, so if you want to use the Esc key in other apps, please turn it off.
Default position of the screen center	The amount of movement to the center of the screen when the JINS ASSIST app is not running. The top-left of the screen is coordinate 0, 0, and can be specified up to 4095. Please turn off the OS mouse acceleration setting.
Display of selection assist pop-up	When selecting by stopping the mouse, it displays on the cursor which direction corresponds to which click.
Sound effect volume	Adjusts the volume of the sound effects.

Command Settings

Setting Item	Details
Nod sensitivity	Sensitivity setting for how fast to move your head to trigger a nod/shortcut or start movement in always-on cursor sync mode.
Wait time until click selection	The waiting time when inputting a click type selection. After this time elapses, it exits click type selection and returns to nod waiting.
Time to confirm click	The speed from when the cursor stops to when it is judged as a stop state and transitions to click type selection. Excludes drop operations.
Time to confirm drop	In a drop operation, the speed from when the cursor stops to when it is judged as a stop state and drops.
Command detection wait	The waiting time when detecting a command before transitioning to the next action. Making it slower allows it to pick up slow nods and left-right round trip movements.
Noise stop detection sensitivity	The threshold for temporarily entering noise stop mode when the device experiences vibration or impact. Making it more sensitive will cause it to enter noise stop mode even with a slight impact.

Cursor Settings

Setting Item	Details
Cursor On/Off	When turned off, the cursor will not move even with a nod.
Cursor movement speed	The movement speed of the cursor during cursor movement.
Cursor acceleration speed	Making the cursor acceleration stronger allows you to move the cursor further and faster when you move your head quickly.
X-axis sensitivity	Multiplies the X-axis movement speed by a coefficient.
Y-axis sensitivity	Multiplies the Y-axis movement speed by a coefficient.
Smoothing strength	The strength of cursor movement smoothing. Making it stronger makes the cursor movement smoother.
Lower limit of low speed	Sets the lower limit of the cursor speed for movements just before the cursor stops.
Continuous cursor movement	When enabled, you can continuously move the cursor after a click by "looking and returning" during click selection. When enabled for D&D, dragging starts first after looking left and returning, and cursor movement is possible after the drop operation is complete.
Wait time for continuous cursor movement	The waiting time between "looking" and "returning" in continuous flow judgment.

Scroll Settings

Setting Item	Details
Scroll start sensitivity	The sensitivity for starting to scroll. For 'Tilt Scroll', it is the magnitude of the tilt angle; for 'Slow Tilt', it is the length of the tilting movement. The sensitivity of 'Tilt Twice in the Same Direction' ignores this setting (the sensitivity of the command settings is reflected).
Scroll speed	The speed of scrolling. It changes the scroll amount and number of scrolls. Depending on the OS, it may not change unless it is changed by two or more steps.

Advanced Settings

Setting Item	Details
Input Type	Changes the type of command input. The standard is click selection, where a nod starts cursor movement, and stopping allows click selection. Auto click automatically performs a left click when stopped. Judge every time uses a nod (down→up head movement) for the click selection flow, and an up→down head movement for the auto click flow.
Axis Type	You can choose the axis setting. The standard is Auto, which assumes use in a sitting position. Right (Left) Vertical Lock assumes that JINS ASSIST is worn on the right (left) side and does not perform posture estimation. Therefore, it will not move as expected if JINS ASSIST is tilted or on the wrong side, but it can be operated even in a supine position.
Load Preset	Loads a preset. Preset settings can be loaded from the recommended settings for each device, as well as those previously saved from "Save as Preset".
Save as Preset	Saves the current settings as a preset. The preset information is saved in the settings app, not in JINS ASSIST, so to load a saved setting, please do so from the settings app where it was saved.
Initialize Auxiliary Software	Initializes and restarts the auxiliary software (not normally necessary). To initialize the settings on the JINS ASSIST side, please load Standard from the presets.

Shortcut Settings

You can assign shortcuts to the following gestures:

Setting Item	Details
Shake head to the left once	You can set a command to be executed when you shake your head once to the left and right, starting by looking left first, and then stopping.
Shake head to the right once	You can set a command to be executed when you shake your head once to the left and right, starting by looking right first, and then stopping.
Shake head to the left twice	You can set a command to be executed when you shake your head twice to the left and right, starting by looking left first, and then stopping.
Shake head to the right twice	You can set a command to be executed when you shake your head twice to the left and right, starting by looking right first, and then stopping.
Shake head to the left three times	You can set a command to be executed when you shake your head three times to the left and right, starting by looking left first, and then stopping.
Shake head to the right three times	You can set a command to be executed when you shake your head three times to the left and right, starting by looking right first, and then stopping.
