Year: May 2022 - August 2022

Lab: DEVCOM US Army Research Laboratory (ARL-WEST)

Project Name: Estimating Perceptual Depth Change using eye-tracker in Real World, Augmented Reality and Virtual Reality.

Responsibilities:

  • Generated research questions and hypotheses related to perceptual depth changes.

  • Developed an experiment to collect eye-tracking data with depth changes.

  • Developed an algorithm to estimate the perceptual depth changes using eye parameters (eye vergence and interpupillary distance (IPD)).

Year: May 2021 - August 2021

Lab: DEVCOM US Army Research Laboratory (ARL-WEST)

Project Name: Tracking Perceptual Depth with Eye Vergence and Inter-Pupillary Distance using eye-tracker data in Virtual Reality.

Responsibilities:

  • Generated research questions and hypotheses related to perceptual depth changes.

  • Developed a method to estimate the perceptual depth changes in VR using eye parameters (eye vergence and interpupillary distance (IPD)) from the eye-tracker data.

  • Analyzed eye tracker data and performed statistical analysis (e.g., ANOVA) using R.

  • Documented the results and findings as scientific publications.

Mentors:

Mississippi State University, USA.

Year: August 2017- April 2022

Responsibilities:

  • Generating and verifying the next-generation imaging technique based on the human visual system improves the clarity of out-of-focus information in Augmented Reality (AR).

  • Conducting experiments and analyzing the effects of AR display context switching, focal distance switching, and vergence-accommodation mismatch on human performance in the AR system.

  • Developing and evaluating a new perceptual measurement method to perceive virtual objects' three-dimensional (3D) locations in optical see-through augmented reality.

  • Adequately calibrating the AR Haploscope's optical system to display the virtual object at the accurate spatial location.

  • Developing and conducting experiments with different depth perception measurement techniques such as trilateration walking, trilateration pointing, perceptual matching, blind reaching, etc.
