User Tests
The validation of the HoviTron technology is split into three phases: PoC-1, US-1 (June 2021), PoC-2, US-2 (June 2022) & PoC-3 (November 2022).
PoC-1, US-1, June 2021
The first validation phase focused on the light-field visualization in the Creal head-mounted display (HMD). For this sake, a test scene was implemented in virtual reality (VR) providing perfect depth maps. This setup (proof-of-concept PoC-1) provided high experimental control and enabled the principal evaluation of the effects of light-field visualization on the use comfort.
In the first user-study (US-1), test-subjects performed realistic pick-and-place tasks and abstract depth matching tasks in VR via a haptic interface as depicted in the picture in the nearby panel.
​
The analysis of subjective and objective data confirmed that light-field visualization reduces the visual effort for the user in terms of mental and physical workload.

PoC-2, US-2, June 2022
In this stage of the project, the video pipeline will not be fully real-time capable and the depth maps might be not of optimal quality, yet.
​
In the related second user-study (US-2), the participants will perform complex interaction tasks with the robot while receiving force feedback on the haptic interface and visual feedback from the robot’s static environment via the real-time light-field renderer STALF. The objects moved by the robot will be augmented in the metric view provided to the user.
