Investigating MR interface patterns for just in time QA information

Abstract

Software testing is the predominant methodology used by the industry to build confi dence in a software product prior to release. The ever increasing complexity and volatility of requirements makes the job of software testers considerably difficult. This project builds upon previous work to investigate how mixed reality design patterns along with context relevant just in time information can be used to improve a software tester's performance. Following an extensive review of design patterns related to mixed reality systems, a subset of these were selected and incorporated into the design and implementation of a prototype utilising the Microsoft Hololens headset. To gain insight into the extent of the effect that the this had on the performance of software testers, a qualitative study, based on thematic analysis, was carried out, in which experts from both fi elds (testing and mixed reality) attended a demonstration of the prototype that showcased how the approach could be used to enable testers to organise a virtual workspace in mixed reality, and how this workspace would then show just-in-time information in relation to whatever the tester was doing at any point in time (as observed by the prototype). These experts were then interviewed so as to gain insight into how such an application could potentially improve and affect the lives of testers, as well as impact the software development industry as a whole. Through the interviews conducted with software testing experts five key themes emerged: `Aiding the tester', `Better Understanding Data', `Impact on the Software Industry', 'Pricing and Integration' ,and 'Potential Software Features'. Findings highlight how such a technology can not only improve a tester's workflow but also positively impact the software industry, however it was also noted that the technology is still held back by its current high pricing and integration costs. Through the interviews with mixed reality experts three themes emerged: 'Interaction', 'Additional Guidance', and 'Developers Adapt'. Findings underlined the importance of interaction within mixed reality applications to improve the experience of both new and advanced users.
