Kathryn Bauer, a recent graduate of New York University's ITP program, presented a project for her master's thesis, titled Ovu, The project tracks and detects fertility easily and fashionably.
One of the many things that makes this implementation so beautiful is that she considered the form of the garment and its implied meaning for her concept. She could have just as easily implemented the idea using a leg or arm band to get it working as a proof of concept. Instead, she chose a garment that implies intimacy and sex, a perfect match for fertility tracking and its context. Kudos to Bauer for striking a perfect balance between concept, integrated intelligence, and garment connotation.
