Heatmaps

Real-Time Heatmap

MouseViz generates a density heatmap in real-time as you record. Areas with more cursor dwell time and clicks appear warmer (red/orange), while less active areas stay cool (blue/green).

The heatmap overlay renders directly on screen with configurable:

• Opacity — Control how visible the heatmap layer is
• Fade over time — Older data gradually fades, keeping the visualization current

3D Heatmap

Pro

A three-dimensional visualization rendered with SceneKit and Metal acceleration. Activity peaks rise vertically from the screen surface, giving you an intuitive sense of where attention concentrated.

Velocity Heatmap

Pro

Shows cursor speed rather than position density:

• Slow movement (reading, examining) appears in one color
• Fast movement (scanning, searching) appears in another

This reveals the difference between focused attention and skimming behavior.

Per-Task Heatmap Filtering

Pro

When using task markers (⌘⇧M or ⌘1–9), you can filter the heatmap to show data from a specific task only. Select a task segment in the timeline and the heatmap updates to reflect only that portion.

Rage Click Detection

Pro

MouseViz automatically detects rapid repeated clicks in the same area — a pattern that indicates user frustration. The detection threshold is configurable.

Cold Zone Detection

Pro

Identifies screen areas with little or no mouse activity, which may indicate discoverability problems in a UI.

Dead Zones

Reveals parts of the screen that received zero interaction during a session. Useful for identifying unused UI elements.
