For this study, wedesigned a QR Code Identity Tag system to integrate into the Turkish healthcare system.
This systemprovides QR code-based medical identification alerts and an in-hospital patient identification system.
Every member of the medical systemis assigned a unique QR Code Tag; to facilitate medical identification alerts, the QR Code Identity Tag can be worn as a bracelet or necklace or carried as an ID card.
Patientsmust always possess the QR Code Identity bracelets within hospital grounds.
These QR codebracelets link to the QR Code Identity website, where detailed information is stored; a smartphone or standalone QR code scanner can be used to scan the code.
The design of this systemallows authorized personnel (e.g., paramedics, firefighters, or police) to access more detailed patient information than the average smartphone user: emergency service professionalsare authorized to access patient medical histories to improve the accuracy of medical treatment.
In Istanbul, wetested the self-designed system with 174 participants.
To analyze the QR Code Identity Tag system’s usability, the participantscompleted the System Usability Scale questionnaire after using the system.
a housing defining a first side, a second side opposite the first side, and a third side joining the first side and the second side;
a display on the first side of the housing;
a touch sensor for receiving a touch input at the display; and
an input component comprising:
a light source within the housing;
an optical sensor within the housing; and
a window on the third side of the housing and configured to transmit light from the light source and to the optical sensor;
wherein the watch is configured to detect a user input with the input component, the user input comprising sliding by the user from a first position against the window to a second position against the window, and execute an action corresponding to the user input.
