Figure 5.

Examples of data from two types of sensors: eye gazing sensors (a–c), and NIRS skeletal muscle sensor (d). Eye gazing data during indoor lead climbing show the climber’s gaze location (green dot) overlaid on a sequence of three images from the scene video camera of eye tracking glasses. The first and second images (a,b) show a climber maintaining their eye gaze on the same hand hold. The third image (c) shows the climber shifting their gaze to the next hand hold. The NIRS sensor data (d) show moderate (60–70%), low (35%), and high (80–85%) muscle oxygen saturation during moderate-intensity (Period A), high-intensity (Period B), and low-intensity (Period C) muscle exertion, respectively.
