Abstract
Hallway testing, Remote Usability testing, Expert review, Automated expert review and A/B testing are the methods commonly used for Usability testing. However, there is no reliable system that integrates Brain Computer Interface (BCI) into the testing process with focus given towards user emotion analysis using electroencephalography (EEG) signals. This paper proposes a system that would be able to identify user emotions while they are conducting usability tests and the results would be able to increase the accuracy of the usability test. In the proposed system the results of the usability test would be displayed in real time on a dashboard and a summary report can be generated for distribution.
Highlights
Brain Computer Interface (BCI) is an area of Computer Science that aims to capture brain activity in the form of electroencephalography (EEG) waves and convert those signals to commands readable by computers using a series of algorithms [1]
The process can be repeated with other emotions as well to obtain a comprehensive analysis. Another advantage of taking the Support Vector Machine (SVM) approach is its compatibility with the Discrete Wavelet Transformation (DWT) algorithm that we explored in the previous section
This paper proposed a web-based system that can be used for usability testing that incorporates BCI into the testing process through emotion recognition
Summary
Brain Computer Interface (BCI) is an area of Computer Science that aims to capture brain activity in the form of electroencephalography (EEG) waves and convert those signals to commands readable by computers using a series of algorithms [1]. A new area that is being explored is the aspect of recognising emotions in real time using EEG waves [4]. This paper proposes a system which integrates real-time emotion recognition to usability testing. This paper intends to propose a usability testing method which incorporates Brain Computer Interface (BCI) into the testing process to identify user’s emotions while using the system that is being tested. The process of conducting usability tests for. BCI would be used to identify the user’s emotions in real time and the data can be used to improve the outcome of the usability tests conducted. We propose a web-based system (dashboard) that would display analysis of user emotions as the usability test is conducted.
