Helmet-based system for improved practice efficiency and athlete safety

A system for use by athletes and their coaches during practice, the system comprising:

• a helmet-based electronic system including:
• a transparent display screen coupled to the helmet, the transparent display screen configured to display information to the user in a video format and a graphical format;
• a sensing system configured to sense a plurality of physiological states of the athlete when participating in a current practice-activity;
• a processor coupled to the transparent display screen and the sensing system, the processor configured to process information concerning the plurality of physiological states;
• and
• a first wireless transceiver coupled to the processor, the first wireless transceiver configured to communicate information concerning the plurality of physiological states,
• wherein a notification is automatically generated when a processing of the information concerning the plurality of physiological states results in a value that indicates that the athlete's physiological state is outside of recommended values when compared to at least one threshold concerning the plurality of physiological states, the notification displayed on the transparent display screen, the notification providing instructions for the athlete to modify the current practice-activity, and
• wherein the instructions indicate to the athlete that the current practice-activity should be shifted to a different practice-activity to provide a reduced level of physical exertion for the athlete.
