BlinkRoll: Vertical Scroll

BlinkRoll is an Android accessibility tool that turns deliberate eye blinks into vertical scrolling, moving long screens up or down in compatible apps. It helps users with upper-limb motor impairments navigate apps and web content without repeated taps or swipes. The front camera recognizes eye blinks and sends a vertical scroll action to the current screen. Key features: - Short close (default): close briefly, then reopen, to move in the configured direction each time - Short or long close: close briefly, then reopen, for the configured direction; hold longer, then reopen, for the opposite direction - Long close: hold closed longer, then reopen, to make one larger move in the configured direction - Primary direction, movement distance, and scroll speed controls - In-app eye-input practice with camera permission only; no Accessibility Service needed - Readjust detection to your eyes - Session distance shown for blink-controlled movement - A small eye icon that shows the current status; show or hide it without watching an ad - Start and stop scrolling from the running-service notification and Quick Settings - Quick-start reminders appear only when you enable them - Stop or pause detection when the screen is off or locked - Optional no-face auto-sleep, off by default: stop the camera after no face is seen for 10, 30, or 60 minutes - Camera frames are processed only on the device and discarded after analysis - Current-screen scrolling through Android Accessibility Service Direction arrows show how the screen moves: ↓ down, ↑ up. Changing the primary direction also reverses both directions in Short or long close. Eye input is not sent when no face is detected, even with auto-sleep off. Privacy: BlinkRoll does not send camera frames, face images, or face landmarks to servers or ad providers, or save them as app files. Detection runs on the device and frames are discarded after analysis. It does not read or store other apps' screen text or content. Ad providers may process device and ad-interaction data to serve ads. Free use and ads: Scrolling and in-app practice are free, with no access pass or ad viewing required. Banner ads may appear in the app; eye input still works if an ad cannot load. Any ad-free period previously earned by completing an ad lasts until its original expiry. Expiry does not block eye input. How to use: 1. Allow camera permission. 2. Try closing and reopening your eyes in the in-app practice area without enabling Accessibility Service. 3. To scroll other apps, turn on BlinkRoll · vertical scrolling in Android accessibility settings. Allow notifications to see the running-service status. 4. Start with Short close. Switch to Short or long close or Long close when needed. 5. Tap Start scrolling, move to another app, and close and reopen your eyes once. Safety: BlinkRoll is not a medical, diagnostic, treatment, or vision protection app. Do not use while driving, walking, or performing dangerous tasks. Stop scrolling and rest if your eyes feel tired or uncomfortable. Recognition accuracy may decrease in very dark environments, strong backlight, or unstable camera conditions.
