Hackathon Winners Presenting On Stage
summary
Three winning hackathon projects built working prototypes in 24 hours: a retail self-driving cart that uses Dialogflow + DeepWave TTS, a Sphero-simulated drivetrain and indoor mapping to guide shoppers and upsell online items; a sign-language aid using Leap Motion → ML.NET with only 30 MB training (58 fps capture) that recognizes lip/hand gestures with prototype accuracy; and “Connected Grandma,” a smartwatch + GPS system with fall detection, push alerts and Alexa integration—demos run live though occasional network lag appears.
