Abstract:
A navigation device with dual airflow sensors. The navigation device includes a first sensor to detect a first airflow in response to movement of the navigation device in approximately a first direction. The navigation device includes a second sensor to detect a second airflow in response to movement of the navigation device in approximately a second direction. The navigation device also includes first and second airflow directors which are aligned with the first and second sensors, respectively. Each airflow director includes multiple openings to direct the first and second airflows across the first and second sensors, and to maintain the first and second airflows substantially independent of one another. The navigation device also includes a microcontroller to generate a two dimensional navigation signal based on input signals from the first and second sensors.
