Method for storing and retrieving digital ink call logs
Digital ink is captured using either a digitizer attached to the serial port of the computer or by a tablet computer having a stylus during the detection, capture, storage and association of ink with particular types of information. An ink log stores handwritten notes that are generated during a phone call. Whenever a call is made or received via a regular telephone or an IP Softphone, the number being dialed or that the call is being received from is used in a search to locate a file associated with this number within an ink log. If a file associated with the called or dialed number exists, then the file is retrieved and all prior ink notes associated with this number, including their time stamps, are displayed in a window that is opened. If a file corresponding to the called or dialed number is not present in the ink log, then a new file is created along with an associated blank window, whereby the user can begin “inking” into this file. Alternatively, a user may highlight a phone number and view the InkLog for the particular number. Upon a user selecting a View Ink Log category, the ink log is accessed and all notes, drawings, etc. that a user generated in all previous calls that where either made to the number or calls received from this number are displayed.
