One exemplary method is performed at an electronic device and includes: identifying a current topography of a putting green and a current position of a first user's ball on the putting green. The method also includes: determining, based on the current topography, a best path from the current position of the first user's ball to a target on the putting green. The method additionally includes: sending, to a projecting device that is distinct from the electronic device, instructions to render a representation of the best path on the putting green. In some embodiments, the method further includes: determining a backswing distance and/or speed and a corresponding follow-through distance and/or speed that allows the first user to hit the ball along the best path and providing instructions to render the backswing and follow-through distances on the putting green."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sport and game simulation systems with user-specific guidance and training using dynamic playing surface","description":"Disclosed herein are sport and game simulation systems, and methods of use thereof.
