Mixed Reality (MR) and Augmented Reality (AR) technologies have revolutionized the way we learn and perceive the world around us. These cutting-edge technologies merge the real world with computer-generated elements, creating a seamless integration between the physical and digital realms. This unique feature allows users to interact with their surroundings in more engaging and immersive ways, providing them with a richer and more meaningful learning experience.
In recent years, MR and AR technologies have gained widespread popularity in various fields, including education and specialized training. These technologies have proven to be highly effective in helping trainees test their skills, visualize abstract concepts, and make better sense of complex data. Whether it’s in the classroom or on the job site, MR and AR technologies offer a range of innovative tools and applications that are transforming the way we learn and work.
From virtual labs that allow students to conduct experiments in a safe and controlled environment to AR simulations that help surgeons practice complex procedures, the potential applications of MR and AR technologies in education and specialized training are vast and exciting. As these technologies continue to evolve and become more sophisticated, we can expect to see even more exciting developments in the years to come.
The University of Calgary has been conducting research to improve the effectiveness of mixed reality (MR) visualizations through the development of new interfaces and systems. One of their latest projects is called HoloTouch, which is designed to enhance MR graphics and charts by using smartphones as physical proxies. The researchers are set to present a paper on this innovative system at the CHI 2023 LBW conference. HoloTouch is a promising technology that has the potential to revolutionize the way we interact with MR visualizations, and its development represents a significant step forward in the field of MR research.
“To me, this paper was inspired for the most part by a work that I published during my final undergraduate year,” Neil Chulpongsatorn, one of the researchers who carried out the study, told Tech Xplore “They both originated from my interest in mixed reality interactions for data representations.”
Chulpongsatorn and his team have conducted various studies in which they have examined how data visualizations can be improved through the use of virtual elements displayed via head-mounted displays like the Microsoft HoloLens. Other research teams have also proposed similar solutions, such as dynamic physical bar charts. While some of these efforts have been successful in producing interesting outcomes, the researchers have found that current MR and AR headsets are not capable of supporting such advanced and dynamic data visualizations.
In their most recent study, the team sought to address this limitation by developing a solution that utilizes widely used devices currently available in the market. They recognized the need to work within the constraints of existing technology, and their approach aimed to circumvent these limitations by leveraging the capabilities of smartphones as physical proxies for enhanced MR graphics and charts. This innovative solution, called HoloTouch, has shown great potential to revolutionize the way we interact with data visualizations and represents a significant step forward in MR research.
“Rather than making physical representations interactive, we pivoted to making virtual representation tangible instead,” Chulpongsatorn said. “Works like MARVIS presented this idea at a high level and demonstrated its potential. Our recent work digs further down to present the foundation of these interfaces as an interaction space for visualization designers to use in the future, as well as evaluating the effectiveness of these interaction models.”
Chulpongsatorn and his team have presented a new system called HoloTouch, which aims to enhance MR visualizations by combining the capabilities of head-mounted displays (HMDs) with the touchscreens of smartphones or tablets. This innovative system allows users to interact with holograms they see on their HMDs by using their smartphone devices to touch and manipulate them. Essentially, HoloTouch bridges the gap between MR and physical reality, enabling users to experience a more immersive and interactive visualization experience. This novel approach has the potential to revolutionize the way we interact with MR graphics and charts and represents a significant breakthrough in the field of MR research.
“The results of preliminary evaluations show that people generally like exploring the visualization with the proxy more than without it,” Chulpongsatorn said. “Particularly, precision and tangibility stood out as strong advantages of the proxy. This suggests that physical interactions with holograms is beneficial to data analysis task, although more work will have to be done before we can draw stronger conclusions.”
The HoloTouch system proposed by Chulpongsatorn and his team could have significant applications for designers and content creators in presenting data to various audiences. This innovative technology provides an immersive and interactive visualization experience, making it a valuable tool for education and professional training. In the future, this system could potentially transform the way we perceive and understand complex data.
The researchers are not content to rest on their laurels, however, and are committed to further improving the system by incorporating new features and interaction styles. With ongoing development and research, HoloTouch could become an even more powerful tool for enhancing MR visualizations and bridging the gap between physical and digital reality.
“As this is a late breaking work, there is still a lot to be done,” Chulpongsatorn added. “For one, the space currently has breadth but not much depth. There are also other interactions that we still need to explore. We talked about some of this towards the end of the paper. More interactions also mean more evaluation to be done, as that is one of our core contributions with this work.”
