Scientist Utilizes Mixed-Reality Device to Scan Tropical Forest

A postdoctoral researcher from Rice University has successfully utilized a mixed-reality headset to measure and analyze vegetation on the forest floor. The research, conducted by Daniel Gorczynski, demonstrated a direct correlation between the diversity of animal species and the mapped habitat in a Tanzanian national park. The findings, published in the journal Ecology, revealed that areas with a greater microhabitat surface area exhibited a richer biodiversity of mammals.

Field research for studying habitats typically requires considerable time and effort. However, Gorczynski managed to reduce the costs associated with this research by incorporating a Microsoft HoloLens headset along with his custom-designed software called VegSense. While the HoloLens was originally developed to enhance work quality in various industries such as manufacturing, engineering, healthcare, and education, Gorczynski and his advisor, Lydia Beaudrot, adapted it to help researchers measure animal habitats.

Due to its mixed-reality capabilities, the HoloLens allows users to perceive both the projected mesh overlaying the forest structure as well as their immediate surroundings. Gorczynski collaborated with scientists from the Udzungwa Ecological Monitoring Center and the University of Florence to conduct the research in Tanzania’s Udzungwa Mountains National Park. The team combined data from Gorczynski’s VegSense measurements from the forest floor with data from motion-activated trail cameras set up to observe mammal populations in the park.

Gorczynski explained, “We identified 31 points within the protected forest to collect paired camera trap and HoloLens data and used a novel type of model to assess the statistical relationship. We found that mammal diversity did indeed increase with forest floor habitat surface area as measured by the HoloLens.”

The research not only revealed an increase in the number of mammal species in high habitat surface area locations but also a greater variety of ecological characteristics among these species. This includes variations in body size and dietary requirements. Gorczynski hopes that these findings will prompt focused efforts to designate and protect habitats with high surface areas.

Gorczynski commented on the importance of tropical forests, saying, “Tropical forests have some of the most unique and diverse mammal communities on Earth. In these forests, mammals play crucial roles in maintaining the ecosystem such as dispersing seeds, nutrient cycling, and regulating populations through herbivory and predation.”

One of the notable aspects of the HoloLens is its user-friendly interface. Gorczynski has successfully trained scientists, technicians, and students in both Tanzania and Madagascar on how to incorporate the device into their data collection methods. He envisions potential collaborations where the standardized and scalable data obtained through the HoloLens can be utilized across multiple research sites.

Impressed by Gorczynski’s work, Beaudrot stated, “Dan knew he wanted to study mammal functional diversity and hit the ground running… He wasted no time diving into his first research project in his first month and proceeded to publish five first-author publications during his Ph.D., including this final HoloLens paper in one of the leading journals in our field.”
