This paper outlines a project called "Virtual-spine" which aims to convert seated posture data into interactive 3D representations of spine movement. Spine movement information is collected from pressure sensors installed at various locations on the seat. Sensor readings are combined with "chair-id" and user "profile" to obtain contextual hypotheses. The output is delivered via a messaging system developed to help prevent harmful and fixed postures in prolonged sitting. A specific setup for evaluation testing is also outlined.
