The Tangible Space Initiative (TSI) project, a multi-campus international research program funded by KIST , had beed pursued for 7 years starting from year 2000 to study the next-generation interaction spaces.

Previously, human computer interaction (HCI) issues in ubiquitous or pervasive computing and virtual and augmented reality were addressed largely in separate research communities. Given major advancements and increased maturity within the individual research areas, it appears fruitful to combined these approaches within a unifying perspective toward the next-generation interaction space.

We have identified three components that form mutually cooperative but distinct areas in TSI:

  • Tangible Interface (TI) mainly provides the interface between the human and the cyberspace. TI has been a major focus of VR/AR research
  • Responsive Cyber Space (RCS) is a virtual space that is responsive to user situation and intentions. RCS has been a main focus of research in simulated environments and artificial intelligence.
  • Tangible Agents (TA) are physical agents that can perform physical interaction on behalf of the cyberspace. TA has been a main focus of the robotics, graphics, and vision fields.

TSI (Immersive Tangible Experience) Concept

Immersive Tangible Experience (ITE) in TSI focussed on immersive exploration of tangible space (both virtual and physical) with haptic feedback. In the following, one person located in immersive tangible experience space surrounded by four screens (CAVE-like) with haptic feedback by SPIDAR that is collocated within the CAVE environment. The virtual lego house is a virtual replica of the physical lego house that is seen by head-mounted display (HMD) and sees the virtual video avatar augmented on physical LEGO house floor.
