Voice-Activated Augmented Reality Heritage Tours

Integration Challenge

The Voice-Activated Augmented Reality Heritage Tours (VAARHeT) enlivens the way visitors engage with Āraiši lake dwelling site from the late Iron Age (9-10 century), at the Āraiši ezerpils Archeological Parks in Latvia, through voice-driven interaction in an XR environment.

By integrating extended reality (XR) and artificial intelligence (AI) technologies, VAARHeT provides a transformative, immersive, and multilingual visitor experience. Expanding the reach of this important heritage site and providing visitors with a unique and engaging way to discover and learn.

VAARHeT addresses key problems faced by open-air museums like Āraiši ezerpils Archaeological Parks.

  1. Meeting Modern Audience Expectations: A key motivation for implementing AR tours in open-air museums is to enhance the visitor experience, making it flexible and entertaining. Visitors need ways to prioritise information according to their preferences and on-site needs, and museum staff need space and time to engage directly with visitors to provide personal and authentic interactions.
  2. Preservation and Resource Strain: Traditional open-air museum experiences, such as guided tours and live historical reconstructions, are resource-intensive, requiring staffing and handmade replicas of archaeological finds. Physical reconstructions and living history can damage sites and artifacts, and can be costly, while facilitating limited visitor numbers.
  3. Season-Independent, Scalable Experiences: Open air museums are limited by shorter tourist seasons. As museums strive to increase visitor numbers off-season, and to extend the interpretation of their sites, they face a strain on staffing resources and the need to respond to increased information queries by visitors.

VAARHeT leverages AI and AR to create an immersive, voice-activated experience for visitors at open-air museums like Āraiši ezerpils Archeological Parks.

Key features include voice-driven personalised tours, multilingual translations, and real-time geospatial content delivered via visitors’ own smart devices. VAARHeT provides a scalable, innovative approach to museum experiences, reducing reliance on resource-intensive physical reconstructions and making heritage content more interactive and accessible year-round.

VAARHeT stands out through its use of voice-activated interaction with a conversational agent for personalised content presentation. It offers real time multilingual translations, making it accessible to international visitors. It presents features geospatially anchored content, providing location-specific experiences. Visitors can use their own smart devices, removing the need for specialised equipment and enhancing scalability. VAARHeT provides a more user-friendly, interactive, personalised, and accessible AR experience for cultural heritage sites.

 

Use Case Description

The VAARHeT project represents a transformative use case for augmented reality (AR) applications in cultural heritage, especially in open-air museums like the Āraiši ezerpils Archeological Parks. Unlike conventional AR tours, which often rely on static content or manual interaction, VAARHeT introduces voice-activated engagement, allowing visitors to interact with a conversational AI that delivers dynamic personalised tours. This makes the experience more interactive, responsive, and tailored to individual preferences, significantly enhancing user engagement.

A standout feature of VAARHeT is its integration of neural machine translation (NMT), which provides real time multilingual support. Visitors can experience live guided tours in their preferred language, breaking down linguistic barriers and making the tours accessible to a wider, more diverse audience. This capability is particularly important to heritage sites that attract international visitors.

Additionally, the solution offers geospatially anchored AR content, where visual effects and contextual information are linked to specific physical locations within the museum site. This feature enriches the experience by seamlessly blending digital content with the real-world environment, creating a more immersive and contextually relevant narrative. By using their own smart devices, visitors can access the AR experience without the need for specialised hardware, making the application scalable, cost-effective, and easy to adopt for museums. VAARHeT’s innovative use of extended reality (XR) technologies enhances the visitor experience while addressing critical challenges faced by cultural heritage sites, such as the resource-intensive nature of physical reconstructions and the limitations of seasonal tourism. Offering a year-round on-demand experience reduces operational strain and expands museums’ capacity to engage audiences. This combination of AI-driven personalisation, multilingual accessibility, and seamless integration with physical environments sets VAARHeT apart as a pioneering application of AR in the cultural heritage sector.
