Patent ID: 8801134

Claim:
A handheld image translation device comprising: a communication interface configured to receive an image from an image source; a first navigation sensor and a second navigation sensor; a position module configured to control (i) the first navigation sensor to capture a plurality of first navigational measurements and (ii) the second navigation sensor to capture a plurality of second navigational measurements, accumulate (i) first incremental translational changes between successive navigational measurements of the plurality of first navigational measurements and (ii) second incremental translational changes among successive navigational measurements of the plurality of second navigational measurements, determine a difference between (i) the accumulated first incremental translational changes and (ii) the accumulated second incremental translational changes, and determine a rotation of the handheld image translation device relative to a reference location based at least in part on the difference between (i) the accumulated first incremental translational changes and (ii) the accumulated second incremental translational changes; and a print module configured to cause a printing substance to be deposited on a medium based at least in part on (i) the image and (ii) the determined rotation of the handheld image translation device relative to the reference location.
