This system is specifically designed for athletes with hearing impairments, offering a more tailored solution compared to generic visual timers. It is portable and modular, making it suitable for use across multiple lanes or venues. Developed locally to suit Malaysian and regional contexts, it helps reduce both cost and customisation time. Additionally, it enables faster reaction responses than traditional methods such as flags or hand signals.

Traditional auditory starting signals used in track events exclude deaf or hard-of-hearing athletes, placing them at a competitive disadvantage. There is a need for inclusive, responsive, and accurate visual signal systems that integrate seamlessly into existing sports formats.

VSD 3.0 is a modular, wireless device that transmits visual and/or vibration-based start signals to athletes. It is powered by a system developed in collaboration between UTM and MSDEAF Malaysia, with ongoing efforts to enhance its portability and robustness for real-world competitions.

The VSD 3.0 is an inclusive wireless visual signalling system developed for deaf athletes in sprint events such as the 100m, 200m, and 400m races. It delivers clear and responsive visual or vibration cues to ensure fair and competitive race starts for athletes with hearing impairments. Unlike traditional auditory signals, which disadvantage deaf or hard-of-hearing participants, VSD 3.0 offers a modular and customisable solution that integrates smoothly into existing track event setups. Co-developed by UTM and MSDEAF Malaysia, the system continues to be improved for greater portability and reliability in real-world competition settings.
