Understanding Tracking Approaches
Interactive installations use two primary body tracking methods—silhouette detection that identifies participant outlines and skeleton tracking that maps individual body joints—each offering distinct capabilities and privacy implications.
Choosing appropriately affects installation functionality user experience and GDPR compliance requiring careful consideration during planning stages.
Silhouette Tracking Capabilities
Silhouette tracking detects participant presence and outline without identifying individual body parts. This approach suits many installations whilst maintaining privacy through anonymous detection.
- Presence detection identifying when participants enter zones
- Position tracking following participant movement across spaces
- Basic gesture recognition detecting arm raises and large movements
- Size estimation differentiating adults from children
- Group detection counting multiple simultaneous participants
- Privacy compliance avoiding personally identifiable information
Skeleton Tracking Advantages
Skeleton tracking maps individual body joints enabling sophisticated gesture recognition and precise interaction. Our experiential installations use skeleton tracking when interactions require detailed body position awareness.

Skeleton data enables complex interactions impossible through silhouette tracking whilst creating potential privacy concerns requiring transparent participant communication and data handling policies.
Privacy and Compliance
Public installations must comply with GDPR and privacy regulations. Silhouette tracking generally proves less problematic through anonymous detection whilst skeleton tracking requires clear signage participant consent and appropriate data processing.
Technical Requirements
Skeleton tracking demands more processing power than silhouette detection. Installations requiring multiple participants or large coverage areas may face performance constraints necessitating powerful computing infrastructure.
Making the Right Choice
Choose silhouette tracking for presence-based interactions shadow play and privacy-sensitive environments. Select skeleton tracking for gesture-controlled games precise body mapping and sophisticated interactions working with experienced technical partners who understand both approaches.
