An example system includes a physiological sensor for generating physiological data associated with a user bearing the physiological sensor. The physiological sensor is configured to wirelessly communicate the physiological data. A portable device includes a touch input device； an accelerometer for generating accelerometer data indicative of activity of the user； wireless communication circuitry for receiving the physiological data； memory for storing the accelerometer data and the physiological sensor data； and a vibrator for providing tactile output to the user. The wireless communication circuitry transmits the physiological data and the accelerometer data to a computer device for use in a presentation application.
