A couple of weeks ago, I received two brand new HTC devices with Near Field Communication (NFC) support. NFC enabled Android phones can read passive RFID tags, but can also use this short-range wireless technology to exchange (small) messages (Android Beam). NFC in that sense competes with bluetooth. Compared to bluetooth, NFC
- requires the devices to be really close (<4cm)
- does not require the devices to pair before communicating.
Although the latter features comes in handy from usuability point of view, it has already been shown that this can help hackers to get access to your phone.
Last week, Hendrik Drachsler, Leonardo Lezcano and myself started brainstorming on how we could use Android Beam to facilitate the handover of medical discharge letters between doctors and patients. Sharing these letters with patients and providing extra services around gives patients more insight on their health. Furthermore the app for patients can be extended with extra functionality to give them for instance more information about e.g. their mediciation. If you want to know more about this handover problem, read further at http://www.handover.ou.nl/.
In this blogpost, I'll show you a (very) early prototype that demonstrates how a doctor can pass a discharge letter to a patient's mobile device via Near Field Communication.
The screenshot shows the mobile device from the perspective of a General Practioner. Screen 2, shows the discharge letters, relevant to a patient. Screen 3 visualizes data available on the discharge letter (e.g. "Problems and Diagnosis", "Medication", etc.)
The following video now illustrates how I can pass this information via android beam to another device.
Note that this is an early prototype and the wireframe for both General Practioner and Patient will be subjected to change. However this video illustrates how NFC technology can be used within the medical domain.
