Tarsier Goggles

about

Rats move their eyes in different directions, spiders see ultraviolet light, mantis shrimp have 12 color receptors, tarsier's eyes are as large as their brain.  Animals perceive the world in fundamentally different ways from our own. We can learn about optics in the classroom setting, but how can we translate the knowledge of how those different traits function into how they affect the personal experience of the world? How might seeing through the eyes of another animal change our understanding of the space we inhabit?

Tarsiers are tennis ball-sized nocturnal primates with enormous eyes, both in absolute size and in proportion to the size of the animal. What would it be like to have eyes of that proportion?

Tarsier Goggles is a virtual reality (VR) project that allows everyone to experience how a tarsier might see. It serves as a tool to engage in hands-on scientific concepts in optics, perceptual science, and evolutionary biology, and also challenges our own thinking about our environment. The experience is self-guided and allows users to toggle between human and tarsier in order to explore different realistic environments with both sets of eyes.

Project in partnership with Sam Gochman

how we built it

Built in Unity3D with SteamVR for the HTC Vive Pro. For various functionalities like teleportation, splash screens, and tooltips for our tutorial, we use Virtual Reality Toolkit (VRTK), an open source library. For many of the visual effects, we used Unity’s built-in post-processing stack. Our assets were built in Maya.

DALI project Tarsier Vision Virtual Reality Experience was selected to present and demo at the prestigious anthropological society event of the year, the Leakey Foundation 50th Anniversary Gala on May 3rd, 2018. The Leakey Foundation plays a pivotal role in the international study of human origins and evolution. It funds important research projects and leads efforts to engage the public with science through educational outreach and science communication. Ben Cooper '18 (DALI mentor and VR specialist) represented DALI alongside project partner Sam Gochman '18 and his advisor, Professor Nathaniel Dominy. Gala guests were enthusiastic to gaze through the eyes of the tarsier and reconsider their own human perception. 

“Many of us learn about how evolution has produced adaptations in visual perception, but it is difficult to communicate why that all matters. By bringing our project to the Leakey Foundation, we have the opportunity to show how design and modern technology can be bridged to science education and how science can be brought to a personal level of understanding and relevance.” – Sam Gochman

Sharing the tarsier project with the Leakey community extended the reach of the important bridge between science education, design, and technology. It was also a unique opportunity for the DALI team to interact directly with leading anthropologists, entrepreneurs and industry leaders from Silicon Valley. The trip was supported by the Dartmouth Anthropology Department and the Nuekom Institute. 

Gochman started working with DALI in January 2018, tested the VR experience at DALI’s Technigala in March, and brought the project to The Vermont Institute of Natural Science (VINS) in mid-May. VINS hosted the project for an afternoon to share with a group of visiting middle schoolers. The kid's reaction to the virtual reality environment was visceral! They jumped when the tarsier jumped and were quick to point out the unexpected differences in vision. The DALI team added an owl component to the experience to bridge the human-tarsier experience with a more familiar animal. It also provides an excellent opportunity to learn about convergent evolution, as well as optics.  

Clearpay Healthcare

Partner David Washer MBA/MPH ‘17 won the Pitch Audience Choice Award for his solution to crippling, unpredictable health care costs. The DALI Lab is partnering with Washer and working with DHMC to develop an app that provides patients with a more transparent view of healthcare costs by allowing patients to look up costs for health care services before they schedule an appointment.  

Pulse

College Pulse is a mobile application and website designed to aggregate and share student public opinion on college campuses. Combining the accessibility and relevancy of social apps like Yik Yak with the accuracy and credibility of surveys conducted by Institutional Research, Pulse is the first reliable, transparent and cost-effective platform for college administrators and students alike to gage campus opinion through polls. As of August 2016, the Pulse team began testing the platform at Dartmouth and plans to conduct its first campus-wide poll in September. We would like to thank the following Dartmouth and national organizations for all of their funding and support: Dartmouth Entrepreneurial Network, Dali Lab, the Office of the President, Student Assembly, Dartmouth Roots, the Student and Presidential Committee on Sexual Assault, and the Stamps Foundation. After rolling out the platform at Dartmouth, Pulse plans to expand to neighboring ivy league schools, beginning with Yale, Harvard and Brown.

TreasureHunt

TreasureHunt is a scavenger hunt creation tool for mobile devices. Users participate in hunts based on real-world locations, completing fun clues of varying types and difficulties along the way. Points and prizes are earned upon completion of a hunt. There is also the option to create clues and hunts based on one’s location, or to use another person’s clues in one’s own hunts. Simple and entertaining, TreasureHunt is a mix between Geocaching and an Easter egg hunt that helps users to explore the world around them.
