Methods and apparatus are contemplated to perform various actions, including: zooming into or out of an image having at least one object, wherein at least some elements of the at least one object are scaled up and / or down in a way that is non-physically proportional to one or more zoom levels associated with the zooming, and wherein, for example, the non-physically proportional scaling may be expressed by the following formula: p=d′·za, where p is a linear size in pixels of one or more elements of the object at the zoom level, d′ is an imputed linear size of the one or more elements of the object in physical units, z is the zoom level in units of physical linear size / pixel, and a is a power law where a≠−1.

The device is a miniature, self-contained solid state orientation sensor. The unit utilizes three magnetometers and three accelerometers to calculate pitch, roll, and yaw (compass heading) angles relative to the earth's magnetic and gravitational fields. The three orientation angles are output in digital RS232 or optional multi-drop RS485. The device can also be programmed to provide raw accelerometer and magnetometer data in true physical units. The device is capable of measuring angles from 0 to 360 degrees on the yaw axis, 0 to 360 degrees on the pitch axis, and −70 to +70 degrees on the roll axis. The yaw output is compensated for errors due to pitch and roll using embedded algorithms. Applications include fast solid state compassing, robotics, virtual reality, down-hole well drilling, and body position tracking for biomedical and multimedia applications.
