Digital Pen OverviewDigital Pen Overview

• The pen – Writes normally but captures pen strokes via a tiny camera and pressure sensors.

• The paper – Each form has unique pattern of dots telling the pen where it is on the page.

• The transmission & communications – Transmits through mobile devices or docked with PCs to networks.

• The software – Provides character recognition, data conversion, data validation, data correction, & others.

• Integration – Integrates data in to back end applications.

• Challenge – How to track the location of patients after their initial assessment at the triage site. Patients may be moved to different locations within an emergency care facility as they are queued, treated, and monitored. Patients may also be moved between facilities/hospitals, in order to obtain needed specialized medical resources, or to balance loads.

• Purpose – It will track patients locations as patients are moved around one of the facility/hospital, or between facilities/hospitals. It helps determining room/bed availability, knowing if a patient has recently been registered, treated, or why he/she is waiting, and monitoring a patient’s total time in care. It helps improvement of decision-making regarding patients care, transportation/equipments, resource allocation, and incident management.
