20110320924 | HANDWRITTEN PAPER-BASED INPUT DIGITAL RECORD MANAGEMENT - A handwritten paper-based input digital record management system and method to facilitate record management by directly accepting handwritten pen-based data input on ordinary paper forms. A user places a paper form on the digitizing surface of a digital computing device and then fill outs the form using handwritten input. A digital version of the handwritten form is simultaneously generated and presented on the screen of the computing device. Embodiments of the system and method also provide instantaneous form updating for any current data and reports any upcoming information that may be needed in the future. This mitigates the need for remote processing of the form. Moreover, embodiments of the system and method enforce completeness of the form and ensure that all necessary sections of the form are completed. Embodiments of the system and method also provide error correction by reconciling any invalidated data found during verification. | 12-29-2011 |
