Alternative navigational systems aren't exactly new, but the concept shown here just might have wings. HAPMAP was one of a handful of projects selected for demonstration at SIGGRAPH's E-tech event, aiming to keep a human's eye away from the map (and in turn, on whatever's in front of them) by developing a system that guides via haptics. With a handheld device capable of both navigating and vibrating, the interface indicates complex navigation cues that follow the curvature of a road or path -- it's far more detailed than the typical "go straight," and there's also opportun
