GRAZE

The Project

GRAZE is an AI-powered AR eyewear system for golfers. It overlays real-time shot guidance — distance, wind, elevation, club recommendation, and aim line — directly into the player’s field of view. A companion app learns your personal shot patterns and provides data-driven club suggestions. It also includes a skill-based social matching feature to help golfers find playing partners. The idea came from the experience of one team member playing a new course and facing a par-4 with a strong crosswind and an elevated green. His GPS watch showed only flat distance, so he pulled a 7-iron. The ball landed 20 yards short and rolled into a bunker. A more experienced player later explained that wind and elevation together added two clubs — a 5-iron with a draw was the right call. That frustration led to one question: Why do you need a human standing next to you to get useful shot-by-shot guidance? We ran into several challenges. The first AR overlay used green text — almost invisible against grass. We switched to white with black outlines. Our IMU sensor drifted after 20 minutes, so we added a fusion algorithm that recalibrates using GPS while walking between shots. New users had no shot history for AI recommendations, which we solved with a population-average model based on handicap. Some golfers also worried about privacy with location-based matching, so we redesigned it to show approximate distance and require both users to opt in before sharing any personal details.
