E-Mail Delivery Mediation System Based on User Interruptibility
To eliminate the distraction caused by inappropriately timed e-mail delivery notification, we constructed a prototype e-mail delivery mediation system. The system was designed to mediate incoming e-mails based on user interruptibility, which is estimated from PC operational activities of the user. The system delivers e-mails at higher interruptibility times, especially at application switching moments, which are considered a substitute for task breakpoints in work which uses PC. A trial experiment with eight participants in an ordinary working environment was conducted. The experiment results suggested that e-mails were delivered at higher estimated interruptibility times and decreased feelings of hindrance regarding incoming e-mails. However, there were e-mail deliveries at low interruptibility moments even though participants were using the system. Therefore, further study must be conducted to improve the system and to conduct analysis on work efficiency.
