Virtual Reality experiences often showcase highly realistic 3D environments, intuitive interactions and unique avatar embodiment scenarios. Maintaining immersion in such environments for a quality experience requires perceiving properties of the immersive virtual environment (IVE) veridically. This is necessary as users interpret spatial information like size, depth and distance from the optic flow provided by the […]

It is often questioned whether task performance attained in a virtual environment can be transferred appropriately and accurately to the same task in the real world. With advancements in virtual reality (VR) technology, recent research has focused on individuals’ abilities to transfer calibration achieved in a virtual environment to a real-world environment. Little research, however, […]

Rapid technological advancements and lowering prices of commercial Head-Mounted Displays (HMD) have led to an increased demand for modern VR applications, many of which, involve the travel and exploration of large virtual environments. Of multiple VR travel metaphors studied in the past, steering is one that is relatively intuitive and straightforward, giving users continuous control […]

This simulation was developed to demonstrate integration of custom 3D printed tangible objects with off-the-shelf VR devices and general use devices like the Microsoft Surface dial. It was demoed during the Tangibles within VR tutorial at the 25th IEEE Conference on Virtual Reality and 3D User Interfaces in Germany on 18th March, 2018. The simulation […]

Users are able to calibrate to various changes to both their own abilities and their surrounding environments. Most calibration studies have examined recalibration to stable perturbations (i.e., a single, constant change). However, numerous real-world experiences involve perturbations that do not remain constant. To understand how unstable perturbations affect calibration in terms of postural sway and […]

The Augmented Reality application resented in this post was created to address the IEEE 3DUI 2017 contest challenge and was selected for presentation at the conference in Los Angeles, USA in 2017. The task was to build an AR application using mobile devices which allows manipulation of object states and parameters present in the scene […]

This research investigate multiple levels of bimanual interaction metaphors in immersive and non-immersive virtual environments using metrology as a test bed. The simulation features a classroom environment where users can learn to use and interact with measuring instruments like Vernier Calipers, Micrometers, etc. They are taught how to operate them to measure objects and take […]

This work investigates the use of Dynamic Adaptive Streaming over HTTP (DASH) protocols and its effectiveness in streaming high quality media. This approach to video streaming adjusts the video quality delivery to the client player based on changing network conditions. We test 2 DASH based algorithms in this study under varying levels of network impairment […]
