Background:

Projective Immersive Displays (PIDs) offer immersive 3D environments.
High costs limit the adoption of current PID technology.
Existing PIDs are prohibitively expensive, with fewer than 100 installations globally.

Purpose of the Study:

To design and implement a cost-effective Projective Immersive Display (PID).
To reduce the cost of immersive display technology for wider accessibility.
To enable diverse applications in telehealth, education, and collaborative systems.

Main Methods:

Identified major cost-driving components in existing PID designs.
Redesigned key components to significantly reduce manufacturing and implementation costs.
Focused on preserving essential functionality while minimizing expense.

Main Results:

Successfully designed and implemented the Cave-let, a low-cost PID.
The Cave-let is an order of magnitude less expensive than comparable immersive displays.
The device retains significant functionality for various applications.

Conclusions:

The Cave-let offers a viable, affordable solution for immersive 3D environments.
Reduced cost barriers can democratize access to PID technology.
This innovation can expand the use of immersive systems in telehealth, education, and collaborative fields.
