Abstract
A portable distance measuring device that works by spanning separately targeted endpoints is described. The device contains a laser distance measuring component and sensing components that track changes in position and orientation of the device, such as accelerometers and gyroscopes. Distance is measured by pointing the laser at an endpoint and measuring the distance to it. Once this measurement is confirmed, the device can be moved to a different vantage location to measure a second endpoint with the laser. The orientation and position of the device for the second distance measurement relative to the first measurement are calculated by the position and orientation sensors. Together these values are sufficient to calculate the distance spanning the endpoints. This calculation is performed by a computer contained in the device and the distance displayed to the user.
