Visualising emotion in support of patient-physician communication: an empirical study
Behaviour and Information Technology, 2022,07
Patient-physician communication is a crucial aspect of clinical diagnoses and treatments. However, there are barriers to effective empathic practices, including consciousness, busy working rhythms, and difficulties recognising patients’ implicit emotional expressions. While previous research has attempted to support asynchronous medical conversations, this study has explored the use of emotion visualisation techniques for synchronous, face-to-face medical encounters. After interviewing doctors to understand user requirements, an emotion-visualisation prototype, EMVIS, was created. The prototype was evaluated in a study with 31 patients and 37 healthcare providers within different specialist groups using a contextualised Technology Acceptance Model (TAM) and follow-up interviews. The results indicated that patients and physicians were generally accepting of emotion visualisation for medical encounters. Patients were more interested in their physicians’ attitudes and intentions, while physicians accepted the visualisation, but their requirements differed according to their skill levels and specialities. Hence, four supportive factors - emotional empathy, careful attention, human connection, and reflective conversation - elicited information on how EMVIS contributed to medical conversations. Five future opportunities for the emotion visualisation of medical conversations were discussed in respect of the human factors and potential requirements. These include communicating uncertainty, addressing user diversity, providing explanatory information, managing attention, and supporting negotiations.

Evaluation of Ambient Light Display for High Information Capacity
Journal of Bjing Institute of Technology, 2018, 27(04):165-172.
Ambient light display presents peripheral information unobtrusively, and it can be context aware and aesthetically enhance specific environment. However, since the abstract characteristic of light,people should pay attention to keep balance between unobtrusiveness and effectiveness, when designing an ambient light display. Especially, in the condition of high information capacity, ambient light displayneed a mechanism to portray information effectively. In this paper, we attempt to evaluate a frameworkwith overlay mechanism for high information capacity. Based on the framework, two ambient light displays are created to support the evaluation work. The evaluation questions are about information understanding, transition and encoding, special output channel, the three aspects. From perception level,interpretation level and experience level, implement the process of evaluation. The results indicate that the framework with overlay mechanism can effectively support communicating varied and specific information. The transitions and information encoding benefit from the proper mapping of states andnotification levels in the framework.
PDFResearch on Multi-Dimension Information Transfer for Ambient Display with Light
Transactions of Beijing Institute of Technology, 2016.10
Light is an appropriate medium for ambient display, which can provide people novel and aesthetical experience and convey ambient information. But since the abstract characteristic of information decoration in light, to convey diverse and specific detailed information and to increase information capacities in ambient displays become the challenges for designer. In this paper, based on the theories of proxemics interaction, the user's behavior to understand their wishes was analyzed, an interaction design framework was explored for ambient display, multiple dimensions and detailed information transfer. Results show that, based on the framework, the information capacity with light can be increased for ambient display with overlay mechanism, with appropriate transitions and keeping balance between unobtrusiveness and effectiveness.
