Acer User Sensing

Why It Exists

Users need automatic device behavior that adapts to their presence and attention without manual lock or wake actions.

How It Works

Acer User Sensing is Acer's AI-powered user presence detection system for Copilot+ PCs. Using on-device NPU processing and the front camera, the system detects whether the user is present, focused on the screen, or away from the device. This enables automatic screen dimming, lock, or wake based on user attention. The system also detects user mood and fatigue through facial expressions for wellness reminders.

Everyday Use Cases

• Presence detection
• Attention monitoring
• Auto screen lock
• Wake on approach
• Fatigue detection
• Wellness reminders
• Power saving

User Workflow

• Front camera captures user presence continuously via NPU analysis
• AI determines attention and presence state
• System applies appropriate action
• User returns and device wakes
• Wellness reminders based on detected fatigue

AI Processing Flow

The front camera captures low-resolution video processed by on-device NPU computer vision models. Face detection and attention tracking determine user presence. Eye tracking estimates focus level. Facial expression analysis detects fatigue. All processing is on-device with no image storage. Privacy is maintained by processing low-res frames without saving to disk.

Inputs / Outputs

Inputs:

• Camera video
• Face detection
• Eye tracking
• Expression analysis
• Attention metrics
• Presence state

Outputs:

• Auto screen lock
• Wake on approach
• Attention-level display
• Fatigue alerts
• Power saving
• Wellness reminders

Known Limitations

• Camera must be unobstructed
• May not detect presence in very dark rooms
• Limited to single user
• Expression analysis may be inaccurate
• Requires front camera

Unsupported Scenarios

• Multi-user presence
• Privacy mode override
• Scheduled presence
• Accessibility integration
• Integration with Windows Hello

Performance Notes

Presence detection in under 200ms; Attention tracking every 500ms; Auto-lock within 3 seconds of user leaving; Battery impact under 2 percent per hour
