  This paper presents development of a smart sensor dashboard for Industry 4.0
encompassing both 2D and 3D visualization modules. In 2D module, we described
physical connections among sensors and visualization modules and rendering data
on 2D screen. A user study was presented where participants answered a few
questions using four types of graphs. We analyzed eye gaze patterns in screen,
number of correct answers and response time for all the four graphs. For 3D
module, we developed a VR digital twin for sensor data visualization. A user
study was presented evaluating the effect of different feedback scenarios on
quantitative and qualitative metrics of interaction in the virtual environment.
We compared visual and haptic feedback and a multimodal combination of both
visual and haptic feedback for VR environment. We found that haptic feedback
significantly improved quantitative metrics of interaction than a no feedback
case whereas a multimodal feedback is significantly improved qualitative
metrics of the interaction.
