Abstract

A system, computer program product and method are provided that smooth handwritten information following the transmission of handwritten data to a second computing device, thereby reducing the memory, processing and communications bandwidth requirements of a first computing device that captured the handwritten information. A system, computer program product and method are also provided for creating new points in the vicinity of at least some of the data points of the handwritten data after transmission of the data, thereby effectively improving the resolution of the handwritten information without increasing the memory, processing and communications bandwidth requirements of the first computing device. A system, computer program product and method are further provided that associate additional data with the handwritten information after the information has been transmitted such that a composite can be created without increasing the memory, processing and communications bandwidth requirements of the first computing device.
