Using multiple sensor-embedded devices enables detection of usage contexts that extend new interaction opportunities (e.g., a gesture and posture composite interface). In this study, we explored design space contextual interactions using mobile device two wrist-worn devices, suggesting Mo-Bi, the bimanual posture-based interface system. Mo-Bi recognizes user's hand compositely utilizing spatial configurations three devices. It provides contextually appropriate layout or application function according to inference based on information. We suggested four scenarios are applicable for common use applications in context. A technical evaluation shows feasibility system, users found enhanced physical comfort stability, providing interfaces fit their context without increasing steps adaptive interface.
