The paper will give an overview of a Biometric Voting System (BVS) which will access the data stored in the database of Adhar card, a Government Id card for each citizen in India, while casting their votes. While issuing the Adhar card a citizen of India needs to give his/her unique biometric data i.e. the fingerprint image and iris image of both e...

A collaborative project between the University of Wisconsin-Madison and the University of Iowa was conducted to understand the feasibility of conducting driving and pedestrian simulator experiments that involve multiple agents (humans) in the simulation. As part of the collaborative project, a distributed driving simulation environment was created...

Augmented reality is standard on many modern smartphone platforms. The distance of virtual objects seen through the smartphone display should be perceived accurately for easy interaction with virtual objects with high fidelity. We investigate whether distance perception through mobile augmented reality devices is affected by an animated avatar. The...

Abstract Background: With Augmented Reality (AR), people interact with virtual content displayed within the real environment. AR cues and objects can be used to conduct rigorously controlled experiments to understand the mechanisms underlying human perception of the environment. Prior work has investigated whether the addition of AR cues to the re...

Although Augmented Reality (AR) can be easily implemented with most smartphones and tablets today, the investigation of distance perception with these types of devices has been limited. In this paper, we question whether the distance of a virtual human, e.g., avatar, seen through a smartphone or tablet display is perceived accurately. We also inves...

Omnidirectional treadmills provide one solution for locomoting through large virtual environments in confined physical spaces. Through two experiments, this paper evaluated locomotion on an omnidirectional treadmill (Cyberith Virtualizer Elite 2) by comparing it to natural walking in an open physical space. In Experiment 1, participants judged dist...

Most modern head-mounted displays (HMDs) do not support the full range of adult inter-pupillary distances (IPDs) (i.e., 45 – 80 mm) due to technological limitations. Prior work indicates that the mismatch between a user’s actual IPD and the IPD set in the HMD (“IPD mismatch”) can affect distance and size judgments in near space (0 – 2 m). Therefore...

Distributed simulation technology offers enormous potential to study the interactions among road users and to assess the impact of new technologies on safety and mobility. A wide variety of studies make clear that the expectations, anticipations, and responses of drivers and non-motorized travelers to the behaviors of other road users are critical...

Augmented Reality (AR) experiments are typically implemented in controlled conditions that are guided by experimenters. The paucity of research on remote AR experiments leads to difficulties for many researchers when conducting remote user studies. Our work provides a preliminary investigation of spatial perception in AR via mobile devices. The ini...

Navigation and wayfinding can be accomplished either by single person or a group of people. Using the help of immersive virtual reality technology, significant research has been conducted to find out how a person can navigate and wayfind in a virtual world. However, there has been little work done that asks how multiple people can collaboratively n...

In this paper, we examine how embodiment and manipulation of a self-avatar's dimensions - specifically the arm length - affect users' judgments of the personal space around them in an immersive virtual environment. In the real world, personal space is the immediate space around the body in which physical interactions are possible. Personal space is...

Augmented reality is an important technology for learning and training, particularly in such tasks as navigation and assembly. These tasks typically require that people be able to accurately localize the position of objects in space; in the case of augmented reality applications, these objects would include virtual objects. Prior work suggests that...
