Abstract

While frustrating and innocuous in many settings, errors can have disastrous consequences for the use of safety critical systems and medical devices. This work-in-progress investigates the effectiveness of an enforced lockout period for reducing errors in a routine task. During the lockout period the user can look at, but not interact with the device interface for a period of 10 seconds before they resume the task after an interruption. Results show that this lockout period can reduce sequence errors by up to 64%. Identifying ways to reduce the disruptiveness of interruptions is important for HCI research given that many devices are now used in settings where interruptions are commonplace. © 2010 Copyright is held by the author/owner(s).
