Abstract

Development of software products can often result in generation of Software Development Waste (SDW). For example, developers may possibly need to rework implementations that cater to ambiguous feature stories. COVID-19 pandemic has influenced the way software development teams operate worldwide. We studied the impact of pandemic enforced work-from-home situation (PWS) on generation of SDW. As a part of a multi-year study, we surveyed 615 participants and interviewed 31 from the software industry across eight countries specializing in various domains. We observed a rise in SDWs, and were able to identify new type of SDW, and other wastes that could be reclassified into existing types of wastes.

Abstract

Students need to understand the assessment of requirements correctness while building software systems. It helps produce products that meet the stakeholder objectives. This poster illustrates an experiment conducted as a tool-based collaborative assignment for assessing the correctness of software products using a Virtual Reality (VR) application as part of a CS300-level course at our University.

Abstract

Software practitioners use various requirement elicitation methods to produce a well-defined product. These methods impact the software product’s eventual traits and target a particular audience segment. Virtual Reality(VR) products are no different from this influence. With the notable rise in product offerings across various domains, VR has become an essential technology for the future. Nevertheless, the type of methods practiced for requirement elicitation still has not been thoroughly studied. This paper presents a mapping study on requirement elicitation methods practiced by VR practitioners in academia and industry. We consolidated our observations based on their popularity in the practitioner community. Further, we present our insights on the necessary and sufficient conditions to conduct VR requirement elicitation using the identified methods to benefit the VR practitioner community.

Abstract

Material science enables us to develop a wide array of materials capable enough to address worldly problems. Velostat is a carbon-impregnated polythene material used to address many problems including gait-related problems. This paper presents a novel approach to analyze a gait-cycle parameter called ‘Stance-phase.’ We ideated, designed, and implemented a low-cost customizable Velostat based sensing mat to calculate the stance phase. We validated our VelGmat using sensor density, sensitivity, process time, and hardware performance metrics. Our validation results helped us improve the effectiveness of gait analysis. We conducted a comparative study between our VelGmat and commercially available mat to understand the contrast in stance phase values. We observed 95% accuracy in stance phase values compared with commercially available mat.

Abstract

Open source software is increasingly being used by various organi- zations. Open source licenses such as GPL, MIT, Apache, Mozilla, BSD, etc have varying terms and conditions for usage, modification, and distribution. Given the availability of source code for open source software, it is difficult to scrutinize adherence of licenses and more often than not it is left to the good faith of organizations and individuals. Violation of licensing terms knowingly or unknow- ingly can lead to copyright, ethical, compliance and security issues. In this paper, we propose a blockchain based approach in managing open source software licenses by enforcing certain practices to improve awareness and increase transparency, thus minimizing the possibility of violations. We present a solution design that relies on the use of 4 modules: InterPlanetary File System (IPFS), Smart contracts, Transaction manager (Meta-Mask) and a Permissioned Blockchain to enforce the conformance of licenses

Abstract

Research in hardware and software support for Virtual Reality (VR) has significantly increased over the last decade. Given the software platform fragmentation and hardware volatility, there is an apparent disconnect among practitioners while building applications in the VR domain. This paper proposes a role-based model template as a meta-model to specify the bare minimum VR software system. We conducted a grounded-theory-based qualitative study on prevailing and phased-out VR SDKs and standards to propose this meta-model. This model template can help VR practitioners build open-source tools to develop, design, and test VR software systems.

Abstract

A method for generating a limitless path in a virtual reality environment ( VR ) for a continuous locomotion within a real physical space using Head - Mounted - Display ( HMD ) device associated with a user is provided . The method includes determining a line segment between two points that corre sponds to an initial path travelled by the user . The method includes detecting a boundary of the VR environment to generate a next line segment . The method includes gener ating and adding a new line segment to end of the initial path . The method includes generating and adding the new line segment to the end of the next line segment . The method includes generating an updated path by adding the new line segment in a direction at the angle of shift angle to the direction of the next line segment .The method includes , configuring to output updated path as two - dimensional points to render updated path into VR environment .

Abstract

Locomotion in a virtual environment within a limited physical space is a complex activity. There exist established techniques to support limitless natural walking in virtual environments. These include Redirected walking, Dynamic path generation, and Walk-Inplace technique, etc. PragPal is one such limitless path generation technique that supports natural walking in virtual environments. It is a novel software-based non-haptic locomotion technique. In this paper, we detail the enhancements to the existing PragPal path generation technique that addresses underlying issues in the technique like (1) path collision at angular turns, (2) effective usage of the physical play area, and (3) the ability to set path-width during path turns.

Abstract

Eye disorders like myopia, hypermetropia, and color blindness affect millions of people around the world. Early detection can help the affected persons take preventive measures against further degradation. However, early detection requires regular testing and visits to trained healthcare professionals to judge the level of disorder. The customization of the test requirements can simplify the method of diagnosis. This paper presents an approach towards developing a virtual reality based low-cost head-mounted device (HMD). The standalone HMD can detect eye disorders like visual acuity, astigmatism, color vision deficiency, and age-related macular degeneration, limiting the involvement of healthcare professionals. We did a user study to test the accuracy of our prototype against various optical test scenarios. The study revealed that the prototype achieved an overall accuracy of 93%. We further aim to deploy the device in economically vulnerable communities with limited access to healthcare infrastructure.
