Campus quads and soccer fields filled with undergraduates during field-testing of augmented reality field trips with students exposing their digital devices to, and working through, conditions far more challenging than the normal lab room activity. Clockwise from top left: persistent heavy rain on a campus with topography, bright and sunny at 114° F on a soccer field, high winds and snow at 10° F on a campus quad, and dusk with bleacher obstacles during a night class on the soccer field.
