README
README.mdCOMP3200 Individual Project - Aidan Reidy
Wearables in sports are commonly focused on individual performance, whereas their use in supporting coordination in team sports remains underexplored. This project investigates real-time haptic feedback to improve movement coordination between teammates, using badminton as a case study. A fully embedded dual-node wearable system was developed, incorporating on-device stroke detection and integrated battery charging, to deliver coordinated haptic cues based on a shared game state.
Across five training drills with two novice participants, haptic cueing improved synchrony by 9.4% on average (measured via cosine similarity) compared to auditory feedback. The system also achieved 93.1% cue recognition accuracy across twenty participants, an 11.95-hour battery runtime under continuous use, and a 14.69ms end-to-end latency, supporting real-time operation. These results suggest that haptic feedback can improve partnered coordination in sports, demonstrating a novel approach to wearable design focused on collaborative performance rather than individual optimisation.

Questions
How big is the DoubleSports.kicad pro PCB?
It measures 38 × 55 mm and has 4 copper layers, 1.58 mm thick.
What parts does the DoubleSports.kicad pro use?
54 parts, built around the ESP32-S3-WROOM-1-N8, DRV2605LDGS, AP2114HA-3.3TRG1 and BQ24075RGT. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the DoubleSports.kicad pro KiCad files?
From the Ameister621/Double-Sports repository on GitHub, at the commit this page was made from: the board is PCB Design in KiCad/DoubleSports/DoubleSports.kicad_pro/DoubleSports.kicad_pro.kicad_pcb and its schematic PCB Design in KiCad/DoubleSports/DoubleSports.kicad_pro/Battery_charging.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DoubleSports.kicad pro design in my own project?
Its repository states no licence, so its author keeps all rights: ask Ameister621 before reusing the design.
