FEATURE · FULLSCREEN · F5
A client view that disappears.
Fullscreen mode removes every element that is not the moving target — no chrome, no controls, no branding.
DEFINITION
Fullscreen mode gives the client an immersive, distraction-free view of the bilateral stimulation target with no interface elements on screen.
What it is
A one-key toggle on the client side that occupies the entire display with just the moving target, honouring the browser's native fullscreen API.
Why it matters clinically
The therapeutic frame benefits from a client display that does not compete with the memory being processed. Fullscreen removes visual noise and reduces the risk of the client noticing a notification mid-set.
How BilateralSync implements it
The client view uses the standard Fullscreen API. The therapist can prompt the client; the client confirms with a single gesture, as required by browser security.
Frequently asked questions
How does the client enter fullscreen?＋
The client presses F or clicks a discreet control on their view. Fullscreen hides the browser chrome and every non-target element.
Can the therapist force fullscreen on the client?＋
The therapist can send a prompt; the client accepts to enter fullscreen. Browsers require a user gesture to switch to fullscreen for privacy reasons.
Does fullscreen work on tablets and phones?＋
Yes. The client view is responsive and fullscreen is supported across modern mobile browsers.
