The Virginia Science Festival is taking place today, Nov 16, from 10am until 4pm, with a series of lightning talks to follow. The event is geared for young people, but it’s enjoyable to everyone. There are dozens of projects featured at the event, many hosted by the College of Science, the College of Engineering, the Center for Human Computer Interaction, the Institute for Creativity, Arts, and Technology, and lots of other clubs and organizations at Virginia Tech and in the area. As in years past, Tech on the Trail has some projects at the event:
Shared outdoor experiences lets participants connect with others in a virtual recreation of the Moss Arts Center. The environment lets people traverse around Moss, with alerts for friends who are elsewhere that are intended to get them engaged with the experience. Derek Haqq is leading this project, assisted by Allison Collier and Setor Zilevu.
How well do you know your leaves provides information about leaves from trees in the New River Valley area. Visitors to the exhibit will be able to see if they can do better than our image recognition algorithm at identifying leaves. This project, led by Neelma Bhatti and Morva Saaty, is part of a larger effort to see how to keep young children engaged in learning tasks.
At the 2018 ACM SIGCHI Workshop on HCI Outdoors, the organizers and participants decided it was time for an academic book that captured key advances in this area. Scott McCrickard, Michael Jones, and Timothy Stelter were selected to edit the book, to be published as part of Springer’s HCI series in 2020. The book, to be titled HCI Outdoors, will describe human-computer interaction (HCI) challenges and opportunities in outdoor settings for communities, groups, and individuals, in domains to include recreation, education, citizen science, wellness, and games. Scales of impact include individuals with personal devices, small groups using technology to support common goals, and large communities of people whose ways of doing and being are affected by outdoor technologies.
The book will be used in a combined grad/undergrad course in Fall 2019, also titled HCI Outdoors, in which course participants will read chapters toward identifying common themes and connections between them, and will craft prototype-centered projects inspired by them. Chapter authors will be invited to participate through invited talks, project sponsorship, writeup responses, or other means.
More information about the book, including how to participate and tentative chapter titles and authors, can be found on the main book site at http://hcioutdoors.net/book/
Virginia Tech’s Institute for Creativity, Arts, and Technology (ICAT) hosts the Virginia Science Festival each year, featuring work from ICAT-affiliated faculty, staff, and students. Tech on the Trail had three projects featured this year:
Derek and Tim are ready!
The Gardenator: How Well Do You Know Your Garden highlights our award-winning garden discovery app made together with the Science Museum of Western Virginia. Grad student Lindah Kotut took the lead on presenting this work, which was implemented by a team of computer science undergrads.
Adventure Meets Research: Citizen Science and Technology on the Trail demoed a challenge (pictured at the right) for participants to “beat the computer” at identifying common plants on the trail. This work featured an app that we have been developing to differentiate between plants found on typical regional hikes. Grad students Derek Haqq and Tim Stelter presented this work, building on the efforts of many others.
Responsive Interior Surfaces: Barklight (pictured at the bottom of this post) is an ongoing effort to create an interactive surface using the bark of a tree and a series of LEDs. A 96″ x 42″ bark panel features a 24 x 48 grid of LEDs connected to Arduinos that are programmed to reflect information and interactions. This represents joint work with faculty Matt Wagner (architecture) and Scott McCrickard (computer science), and students Tianyu Ge, Connor Smedley, Sidney Holman, Shuo Niu, Tom Phan, and many others. This project is funded by an ICAT SEAD grant.
Big thanks to everyone who came out to the festival. It’s been growing every year, and we’re happy to be part of this showcase event for ICAT and the region.
Last summer, ICAT joined the VT Paleobiology Research Group to document the excavation of a phytosaur skeleton. The group worked in the Triassic red beds of Wyoming, hauling over 40 pounds of equipment across ridges in 90 degree heat. ICAT’s role was to take technology on the trail by setting up an array of cameras at the dig site, toward crafting an array of cameras that would capture what went on in a dinosaur dig.
The current state of the project will appear at next week’s Virginia Science Festival, and a completed video, merged with audio, will appear at ICAT Day on April 30, 2018.
Today’s preview presentation started with a description of the experience, touching on the scientific needs but (since it was an artist who was presenting it!) focusing on the crafting of a visually appealing representation of the experience. Video of the experience was collected using a set of 8 GoPro cameras, modified with wide angle lenses. There was a major labor cost in hauling the equipment to the dig site, setting it up, making sure it was properly calibrated, taking it down, bringing it back to the camp site, and spending hours downloading the collected video and charging the devices. The presentation then moved to The Cube to provide a 360 3D immersive experience on what it’s like to dig up fossils.
Our Technology on the Trail initiative has explored how pictures are an important part of many people’s hiking experience. Tim Stelter found it cumbersome to have a single GoPro mounted to his chest on his 50-mile hike (though it did lead to over 2000 pictures of his adventure), so it’s difficult to imagine hauling such a large collection of equipment even a relatively short distance. We’ve explored ways to automatically take pictures that go beyond the mundane. Many people have crafted a time-sequence picture series of their hike. One of Ellie Harmon’s most valued outcomes from her PCT hike was the picture-a-day she identified, whereby she would choose one picture (and no more!) at the end of each day that captured her experience. I’m going to challenge students in my class this spring to identify ways to use sensors to find (potentially) good times to take pictures, similar to the efforts by the Google Clips project.
But this group certainly takes it to a different level. They’ve identified a way that technology can contribute to a better understanding of science by combining the talents of experts in technology, art, and science. I look forward to the next steps from this group!
