摘要： Disclosed are various embodiments of a navigation input device, and methods, systems and components corresponding thereto. According to some embodiments, the navigation input device has a large depth of field associated therewith and employs time- and/or frequency-domain processing algorithms and techniques. The device is capable of providing accurate and reliable information regarding the (X,Y) position of the device on a navigation surface as it is moved laterally thereatop and thereacross, notwithstanding changes in a vertical position of the device that occur during navigation and that do not exceed the depth of field of an imaging lens incorporated therein. According to one embodiment, the navigation input device is a writing instrument that does not require the use of an underlying touch screen, touch pad or active backplane to accurately and reliably record successive (X,Y) positions of the writing device as it is moved across and atop an underlying writing medium.
