  Smart and IoT-enabled mobile devices have the potential to enhance healthcare
services for both patients and healthcare providers. Human computer interaction
design is key to realizing a useful and usable connection between the users and
these smart healthcare technologies. Appropriate design of such devices
enhances the usability, improves effective operation in an integrated
healthcare system, and facilitates the collaboration and information sharing
between patients, healthcare providers, and institutions. In this paper, the
concept of smart healthcare is introduced, including its four-layer information
architecture of sensing, communication, data integration, and application.
Human Computer Interaction design principles for smart healthcare mobile
devices are outlined, based on user-centered design. These include: ensuring
safety, providing error-resistant displays and alarms, supporting the unique
relationship between patients and healthcare providers, distinguishing end-user
groups, accommodating legacy devices, guaranteeing low latency, allowing for
personalization, and ensuring patient privacy. Results are synthesized in
design suggestions ranging from personas, scenarios, workflow, and information
architecture, to prototyping, testing and iterative development. Finally,
future developments in smart healthcare and Human Computer Interaction design
for mobile health devices are outlined.
