This week I improved my implementation according to the result in the pilot study and finalised the experiment on Wednesday. I also finished booking subjects, and the experiment will start on next Monday. It will take about 1 hour and 10 minutes per subject, including 10 minutes instruction explanation and training time.
As the logging format is similar to the external dataset, so I think after the experiment, I could modify previous data analysis scripts to get some basic feature results. However, I still need explore more "letter specific" features before the end of the analysis.
