Développer d’un système électronique pour moduler le son en fonction de la vitesse et de l’accélération de la rondelle afin de donner toutes les informations utiles aux joueurs et ainsi de retrouver la position et la trajectoire de la rondelle même lorsque elle est stationnaire ou dans l’air.

-Description en anglais seulement-

The challenge of playing hockey for visually disabled/ blind people

  • Developing an electronic system to modulate the sound according to the speed.
  • Developing an innovative protective case to protect the electronic assembly.
  • The hockey puck must be light enough to ensure the fun and safety of the game.
  • Being robust and resistant to the very high impact forces in freezing conditions.
  • The entire device must allow the hockey puck to cross the skating rink without deviating from its trajectory.
  • It must be activated easily and have enough energy to remain activated for more than 2,5 hours.

Adaptive hockey puck for visually disabled/blind people

  • It is a plastic puck of 5cm x 15cm.
  • Electronic audible system gives visually disabled players all the information to be aware of the position and the path of the puck on the skating rink.
  • Modulating the sound according to the amphitheater variety using a mobile application.
  • Collecting static data related to the game.
  • Innovative process based on two mechanisms: magnetic and kinetic.

Audible hockey puck system presents multiple advantages compared to traditional hockey pucks

  • Resist the impacts of the game and the cold conditions.
  • Localization of the hockey puck even stationary or in the air.
  • Variation of the tones according to the speed/acceleration/altitude of the hockey puck.
  • Get started automatically without opening the protective case to activate it.
  • Energy efficient and rechargeable.
  • Adjustment of new sounds depending on the skating rink.
  • New speaker design with optimal sound.
  • Wireless communication.
  • Bigger hockey pucks for different visual handicaps.

Market applications

  • Hockey players with visual handicap
  • Other sports of visually handicaps that include a ball with integrated electronic system

Business opportunity 

  • Technology available for licensing.

Main inventors

Professor in Electric Engineering department- École de technologie supérieure-Université de Québec à Montréal

Steve Vezeau
Professor in Electric Engineering department, ÉTS-UQAM

Prof. Vezeau is interested in the methodological issues of integrating ergonomics into the design process -including the investigation methods of the activity in user-centered design approaches- about how industrial designers integrate human components into product design, user participation in the design process and simulation/validation techniques with users. It also looks at the cognitive process of designers. His most recent projects concern transport equipment, hand tools and workstation design. Since 1991, his research has been done in the Groupe 3D laboratory, where he co-founded with Jean-Luc Doyon and Nicolas Gagné.


Mounir Boukadoum
Professor, Director of Microelectronic-Prototyping  Laboratory, UQAM

Mounir Boukadoum first taught electronics at Houston Community College before joining the University of Quebec in Montreal in 1984. He has since developed 13 courses in electrical engineering and 3 in computer science, as well as 4 laboratories. including digital signal processing. He is the author of the book “Signals and Linear Systems”, published by Guérin. His research interests, initially focused on instrumentation and biomedical signals, with clinical applications in mind, are now focused on applications of artificial intelligence in different fields, and on instrumentation and communications systems.


Frédéric Nabki
Professor in Electrical Engineering Department, ÉTS

Prof. Nabki Prof. Frederic Nabki received the B.Eng. degree in Electrical Engineering with Honors from McGill University in 2003, where he graduated with distinction. In 2009, he completed a Ph.D. degree in Electrical Engineering at McGill University in RFIC and MEMS. From 2008 to 2016 he was a Professor in microelectronics engineering at UQAM. He is now an Associate Professor in the Department of Electrical Engineering of the École de technologie supérieure (ETS), a constituent of the University of Quebec. Nabki’s research interests include microelectromechanical systems (MEMS) and RF/analog microelectronics, the integrating of MEMS devices with CMOS phase-locked loops, ultra-wideband transceivers, and MEMS interface circuits.
