Wearable Sensor (Golf)
Also known as: swing sensor, clip-on swing tracker
A wearable sensor is a small device clipped to a glove, grip, or belt that measures swing data — like tempo, plane, and swing speed — directly from its own motion, as an alternative to camera-based video analysis.
Wearable golf sensors are small devices attached directly to the golfer or their equipment — commonly on a glove, under the grip, or clipped to a belt — that use internal motion sensors (similar to what a smartphone uses to detect orientation and movement) to measure swing characteristics like tempo, swing plane, and clubhead speed directly from the device's own motion through the swing, rather than by analyzing a video image afterward.
Because wearable sensors measure motion directly rather than inferring position from a camera image, they can be less affected by the lighting, camera angle, and framing issues that limit video-based pose estimation. The tradeoff is that they typically report a narrower set of specific numeric metrics rather than a full visual reconstruction of body position, and they require purchasing and correctly attaching a physical device before every session rather than simply pointing a phone camera.
Wearable sensors and video-based analysis are complementary approaches to the same underlying goal — quantifying the swing — and some golfers use both together, cross-checking a sensor's tempo reading against what a video overlay actually shows.
Example
A golfer clips a small sensor under their grip before a range session and gets an instant tempo ratio and swing plane reading after every shot, without needing to set up a camera at all.
In SwingVantage Motion Lab
SwingVantage is a video- and pose-based system rather than a wearable-sensor product — it infers swing characteristics from camera footage instead of from a device attached to the golfer or club. Both approaches are legitimate ways to quantify a swing, and a golfer using a wearable sensor alongside SwingVantage's video analysis can reasonably cross-check the two.

- Motion CaptureMotion capture records a golfer's body movement in three dimensions, traditionally using reflective markers and multiple cameras, to build a precise digital skeleton of the swing for biomechanical analysis.
- Launch MonitorA launch monitor is a device that measures ball and clubhead data at impact — ball speed, launch angle, spin rate, and club speed — using radar or camera sensors to quantify a shot instead of relying on how it looked.
- Vertical Ground ForceVertical ground force is the downward-then-upward push a golfer generates against the ground during the downswing, measured on force plates as a multiple of body weight, and it is one of the clearest physical contributors to clubhead speed.
