Evaluating Quality of Experience of Wireless ECG Monitor
Da Xu, Chenguang He, Ye Li · International Conference on Control Engineering and Communication Technology · 2013
Quality of Experience (QoE) which describes users' comprehensive feeling to communication systems is the key to achieve consumers' graces. Wireless ECG (electrocardiogram) monitor is a remote health monitoring system. The users of wireless ECG monitor are usually doctors, patients or patients' family. These users have tough requirements for QoE of the system. So it's necessary to research the QoE of wireless ECG monitors. In this paper, we explore how information quantity received influences QoE of mini-hoter (one kind of wireless ECG Monitor) and simulate the QoE curve of information quantity aspect following the duration of ECG data transmission. Then we conduct investigations to users' experience on energy consumption and fit the relationship between user experience and energy consumption. We put forward assumptions about how the QoE on energy consumption and QoE on information quantity participate in comprehensive QoE. Using the fitting functions and measured data, we confirm the multiplicative relationship between QoE and various factors.
