Comprehensive Validation Workshop Completion
Validation workshop at Āraiši Ezerpils Archaeological Park engaged 39 museum visitors across three intensive testing days from 14-16 July 2025, comprehensively assessing three voice-activated XR applications through structured usability testing, task completion observation, System Usability Scale measurement, added value rating, Net Promoter Score calculation, and qualitative feedback collection. Results demonstrated application-dependent value propositions with experiential educational content including VR archaeological building reconstruction achieving 3.6-4.0 out of 5 added value ratings substantially outperforming theoretical information delivery through AR welcome avatar at 3.2 out of 5, whilst AR translation concept received mixed reception with German-English language pairs showing promise despite AR wearable hardware limitations and Latvian minority language quality failures preventing deployment recommendation in current implementation state. System Usability Scale scores averaged 59 percent across pilots, falling below 68 percent consumer application acceptability threshold yet remaining within ranges typical for complex professional tools during initial deployment prior to iterative refinement, indicating usability proved adequate for motivated users with appropriate support though requiring improvement for unsupervised mainstream adoption meeting consumer product quality expectations. Net Promoter Scores ranged from negative 14 for translation application limited by wearable ergonomics and language quality to positive 61 for VR educational experience garnering overwhelmingly positive reception, highlighting critical importance of matching technology modality and implementation quality to specific use case requirements rather than assuming universal voice interaction value regardless of application context or deployment execution quality. Validation achieved Technology Readiness Level 7 representing system prototype demonstration in operational environment with authentic user populations, positioning applications substantially ahead of laboratory validation or controlled testing that would remain at TRL 4-5 without real-world deployment evidence.
User Demographic Representativeness and Recruitment Success
Participant recruitment through Āraiši museum professional networks achieved 39 total participants exceeding VOXReality programme minimum 30 participant requirement whilst maintaining demographic representativeness matching validated visitor persona developed during design sprint. Recruited cohort demonstrated predominantly female participation (59 percent) reflecting actual museum visitor gender distribution, age concentration in 30-50 range matching primary family visitor demographic, professional occupations and higher education backgrounds typical of cultural heritage enthusiast populations, Latvian native speakers with strong English comprehension enabling interaction with English-language prototype whilst possessing linguistic knowledge for translation quality assessment, daily mobile phone usage with approximately 50 percent prior VR exposure and one-third previous AR application familiarity primarily through gaming, over 75 percent chatbot experience with majority reporting daily conversational AI interaction, and nearly universal classification as regular or very frequent museum visitors providing informed perspectives on heritage visitor experience quality standards. This demographic profile validated recruitment success achieving representative sampling rather than convenience selection from technology-enthusiast early adopters potentially unrepresentative of mainstream museum visitor populations, enabling confident generalisation that validation findings reflect likely operational deployment reception rather than artificially positive results from biased samples exhibiting unusual technology comfort or heritage engagement enthusiasm. Test sessions followed rigorous ethical protocols approved through Maynooth University research ethics review, implementing informed consent procedures, participant wellbeing monitoring, voluntary participation without coercion, withdrawal accommodation at any point, anonymisation through participant code assignment, EU-jurisdiction data storage, five-year retention limits with automatic deletion, and GDPR compliance throughout data collection and analysis phases.
Differential Value Propositions and Strategic Development Insights
Validation evidence generated critical understanding that voice-activated XR value for heritage contexts proves highly application-dependent rather than universal benefit applicable regardless of specific use case characteristics. VR archaeological education achieved strongest validation with 61 Net Promoter Score positioning experience in "great" category between 30-70 range, 97.4 percent of participants considering application positive or neutral addition to museum experience, and qualitative feedback concentrating praise on educational value, historical accuracy, and immersive presence whilst voice interaction received appreciation for controller-free accessibility enabling VR adoption by non-gaming populations though content discoverability challenges from unlabelled elements suggested hybrid voice-visual interface superiority over pure voice-only paradigm tested. AR welcome avatar demonstrated functional technical operation with 92.1 percent acceptable latency perception yet suffered from AI accuracy limitations affecting approximately 25 percent of interactions through factual errors or hallucinations rated as severity 4 usability catastrophe preventing deployment recommendation, producing modest 16 Net Promoter Score revealing theoretical information delivery better served by conventional digital FAQ or chatbot without elaborate AR avatar complexity creating unnecessary spatial interaction requirements and 3D rendering overhead. AR translation showed strong performance for German-English language pair whilst Latvian quality proved unacceptable combined with ActiveLook AR wearable causing eye strain and illegibility yielding negative 14 NPS, though mobile phone display variant demonstrated functional adequacy suggesting modality selection rather than fundamental concept proved problematic. These differential outcomes validate selective technology application principle: heritage platforms should concentrate investment on experiential spatial applications where immersive delivery provides unique capabilities whilst conventional solutions adequately serve theoretical knowledge transfer and routine information access, informing Culturama Platform development priorities focusing defensible competitive advantages rather than comprehensive capability coverage regardless of technology appropriateness.
