Rock climbing is a fun, vigorous activity that many people enjoy, no matter their level of experience. The level of difficulty is something rock climbers are able to choose based on the color route and the climbing grade. However, for colorblind climbers this poses an awkward challenge -- figuring out what climbing holds are "on" for a given route. In order to relieve the frustrations felt by colorblind climbers from this impediment, SHERPA uses AR to highlight and label climbing holds of the same color, clearly identifying possible routes users can take.
