<div class="mw-heading mw-heading3"><h3 id="Compass">Compass</h3></div>
<p>The <a href="Orbita_mouse" title="Orbita mouse">Orbita mouse</a> is the first commercially released non-tablet rotating mouse. Licensed and commercialized by Australian company <a rel="nofollow" class="external text" href="http://www.cyberesport.com">Cyber Sport</a>, the Orbita is equipped with a patented compass mechanism which solved the problems which plagued earlier rotating mechanisms. The inbuilt compass provides the mouse with ability to detect rotation based on the Earth's magnetic field so that it can accurately maintain orientation once the ‘up’ direction is specified. The round design makes it completely rotatable, spinning freely on ball bearings, and is usable at any angle due to the ‘push and squeeze’ button configuration encased in a silicone soft shell. The mouse reports rotation as scroll wheel commands so compatible with most applications.
</p><p>Due to the round shape the Orbita mouse is commonly confused as being similar to the original, circular <a href="Apple_mouse" class="mw-redirect" title="Apple mouse">USB iMac mouse</a>. However, the two mice are functionally different, primarily because the iMac's mouse is not a rotating mouse. The Orbita, unlike the Puck mouse, is designed to be ergonomic, with the round shape lending practical aid to the mouse's spinning action, and is not a purely æsthetic trait.
