Touchable Holographic Solutions (THS) are an application type in Augmented and Mixed Reality (AR/MR) environments. Evaluating THS requires considering Usability and User eXperience (UX), particularly Immersion and Presence, often overlooked by current methods. A systematic mapping study and exploratory search revealed gaps, such as the lack of a unified instrument for THS usability and UX evaluation, methods that address THS-specific aspects, and challenges in adapting general evaluation technologies. To bridge these gaps, we present the Usability and User Experience Evaluation in Touchable Holograms (UUXE-ToH) questionnaire, with 67 Likert scale items and three open-ended questions. A validation study with 13 experts provided quantitative data and qualitative feedback. Results confirm the UUXE-ToH’s efficacy and offer insights for improvement. This research contributes to Human-Computer Interaction (HCI) by introducing a validated tool for evaluating THS, integrating hedonic and pragmatic aspects, and supporting early problem identification in development, accessible to professionals with diverse UX expertise.
