Free head-tracking software for head-controlled pointers

The short answer

If you want to move a pointer with your head using an ordinary webcam, the free tools most often considered are Camera Mouse (Windows), Enable Viacam, also called eViacam (Windows and Linux), the Head Pointer feature built into macOS accessibility settings, and Google's open-source Project Gameface. The best choice depends mainly on your operating system and how you want to click. No independent test results were available for this article, so the comparison describes how each tool is designed to work. It does not rank them on measured accuracy or speed.

These tools use your webcam's video, not its microphone. A webcam's built-in mic has no effect on head tracking. The microphone only matters if you pair head pointing with voice commands, which is covered in a later section.

Free options at a glance

Tool | Platform | How the pointer moves | How clicking usually works

Camera Mouse | Windows | Follows a facial feature you select, such as the tip of the nose | Dwell clicking: hold the pointer still for a set time

Enable Viacam (eViacam) | Windows, Linux | Open-source tool that follows face movement in the camera image | Dwell clicking with adjustable timing

Head Pointer | macOS, built in | Follows head movement through the built-in or a connected camera; turned on in the Pointer Control accessibility settings | Alternative pointer actions, which can include dwell, switches or facial expressions depending on macOS version

Project Gameface | Check current releases for supported platforms | Open-source tool in which head movement moves the cursor | Facial gestures mapped to actions, such as opening the mouth or raising the eyebrows

Platform support and features change between releases. Before you install anything, confirm on the developer's own page that the current version supports your operating system version.

Two tools are often confused with these. Windows Eye Control is built for eye tracking and needs dedicated eye-tracker hardware rather than a standard webcam. Head-tracking programs made for games, such as opentrack, mainly control the in-game camera view, for example in flight simulators. They are not designed as desktop pointer replacements.

How to choose

• Operating system: on a Mac, try the built-in Head Pointer before installing anything else. On Linux, eViacam is the main option listed here. Windows users have the most choices.
• Clicking method: dwell clicking needs no extra hardware but can cause accidental clicks. Facial gestures or external switches can be more deliberate. Choose based on the movements you can make reliably and comfortably.
• Tuning controls: check for adjustable pointer speed, acceleration, smoothing and dwell time. These settings usually matter more for day-to-day comfort than which tool you pick.
• Maintenance: an actively maintained tool is more likely to keep working after operating system updates. Check when the most recent release came out.
• Privacy: head tracking processes a continuous camera feed. Check the tool's documentation to confirm the video is processed on your device and not uploaded.

What to check about your webcam

Most of these tools are designed to work with standard built-in or USB webcams. This article had no tested minimum requirements to report, so check each tool's documentation for its own requirements. In general, tracking works best when the camera has a clear, stable view of your face. That means even lighting from the front, no bright window behind you, and the camera at roughly eye level so small head movements show up clearly in the image. A higher frame rate generally helps the pointer feel smoother. A higher resolution does not always help.

Where the microphone fits in

Many people pair a head pointer with voice control, using head movement to position the pointer and spoken commands to click, type or switch apps. Windows and macOS both include built-in voice control features. In that setup, microphone capture quality directly affects how reliably your commands are recognized.

Keep three things separate. Capture is how well the microphone picks up your voice. Playback is what comes out of your speakers or headphones. Processing is any noise suppression or gain control applied by the operating system or app. A webcam's built-in mic sits farther from your mouth and often picks up more room noise. A separate microphone placed close to you usually gives speech recognition a cleaner signal. Whether a particular webcam includes a microphone, and how it performs, varies by model. Check the manufacturer's specifications, and keep in mind that specifications are not the same as independent test results.

Getting set up

• Start with the lowest pointer speed and increase it gradually.
• Set a longer dwell time at first to avoid accidental clicks, then shorten it as you gain control.
• Keep a fallback input available, such as a keyboard shortcut, switch or a helper, for pausing or turning off tracking.
• Recalibrate or re-center the tracking if you change position, lighting or camera.
• If you use voice commands, test your microphone in your operating system's sound settings before blaming the head-tracking tool for missed commands.

What this article could not confirm

• No independent accuracy, latency or comfort measurements were available for any of the tools listed.
• Current version numbers, release dates and exact operating system compatibility were not verified. Confirm these on each developer's page.
• The tools are generally distributed free of charge, but no dated pricing or licensing source was supplied. Confirm current terms before relying on them.
• No model-specific webcam or microphone data was supplied, so no camera or mic recommendations are made here.
