Usability and User Experience Questionnaire Evaluation and Evolution for Touchable Holography

Abstract

Augmented and Mixed Reality enables applications where users engage in natural hand interactions, simulating touch, termed touchable holography solutions (THS). These applications are achievable through head-mounted displays and are helpful in training, equipment control, and entertainment. Usability and User eXperience (UX) evaluations are crucial for ensuring the quality and appropriateness of THS, yet many are assessed using non-specific technologies. The UUXE-ToH questionnaire was proposed and subjected to expert study for content and face validity to address this gap. This study enhances questionnaire credibility and acceptance by identifying clarity issues, aligning questions with study theory, and reducing author-induced bias, offering an effective and cost-efficient approach. The study garnered numerous contributions that were analyzed qualitatively and processed to refine the questionnaire. This paper introduces the UUXE-ToH in its initial version, details expert feedback analysis, outlines the methodology for incorporating suggestions, and presents the enhanced version, UUXE-ToH v2. This evidence-based process contributes to a better understanding of usability and UX evaluation in the THS context. UUXE-ToH can impact the quality of life of users of solutions applied to education, health, and entertainment by helping develop better products.
