A Study on the Usability of Hand-Held and Wearable Head-Mounted Displays in Clinical Ward Rounds.

摘要

In this thesis research, we investigate the usability of hand-held display (Tablet PC) and wearable head-mounted display (Google Glass) interfaces and their effect on doctor-patient interaction during clinical ward round in the hospital. We looked at existing literature to identify existing research about our topic. Using a User Centered Interaction Design process we developed a prototype hybrid system that used both a hand-held and head-mounted display. An evaluation of this prototype with a hand-held system and a paper based interface was performed in a simulated patient roomwith 20 doctors and 5 patients. The participants were observed, surveyed, and interviewed about their experiences. Generally, the patients had a high satisfaction rate and felt the interfaces were not causing the doctors to lose focus on them. The doctors found the hand-held display by itself and existing paper-based interface to be the most usable and least distracting interfaces for accessing patient information during clinical ward rounds.
