摘要： There is described a dual resolution sensing system configured for low resolution, high speed positioning determinations and high resolution, slow speed motion tracking, said system comprising: a primary grid of overlapping lines formed at a first spacing; and a secondary grid formed about the lines of the primary grid and comprising overlapping lines formed at a second spacing that is smaller than the first spacing, and wherein the primary grid and the secondary grid define a matrix of capacitance sensing junctions at the crossover points, and wherein the primary grid and the secondary grid are configured to define clusters of high resolution pixels, wherein the clusters are spaced from one another by a distance that is greater than the second spacing; and wherein the sensing system is configured to: detect macro finger movements with the primary grid, and detect small incremental finger movements by tracking movements of fingerprint ridge and valley features with the secondary grid.
