Based on their naked-eye view or a slow-motion video, they dock him points for things like not rotating part of his body a full 360 degrees. The not-quite-perfect camera angle leaves viewers doubtful and the athlete trudges off, shaking his head. For those moments, some numbers from highly precise wearable or on-board motion sensors could come in handy. Prototypes of such devices are popping up in freestyle sports such as skateboarding and bicycle motocross, or BMX. Now, researchers are making headway in snowboarding too; one group presented its system earlier this month at IEEE’s Body Sensor Network Conference in San Francisco. The system, developed by researchers at the digital sports group at Friedrich-Alexande...
