Oblong Industries 0000054 ユーザーズマニュアル

The Oblong ultrasonic wand is a new type of input device uniquely suited to support multi-
user, multi-screen, interaction.

The ultrasonic wand is a hybrid ultrasonic and inertial tracking device. It must be used in 
an environment with fixed ultrasonic emitters; these emitters produce distinct pulses that 
are detected by four ultrasonic sensors on the body of the wand. The wand also contains 
an “inertial measurement unit” that provides information on the wand’s orientation and 
motion, and a button press detection circuit. The wand continually sends these data to 
Mezzanine using radio frequency (RF) signals. Mezzanine then computes the wand’s 
position and orientation in the room and animates interface elements in response.

The wand can be used either as a traditional pointing device, or as a gestural input device, 
allowing fluid and complex maneuvers to be executed simply. Both the pointing and 
gestural inputs are enhanced and modified by a single button on the wand to control all 
application functionality. There are three buttons on the wand, one on each of the three 
sides of the device, but they are functionally equivalent. 

Oblong’s Mezzanine product is a multi-user, multi-screen, multi-device collaborative 
environment. The ultrasonic wand is the main control device for Mezzanine. Mezzanine 
software operation and features are not covered by this document.
