Sarah Wiseman, a PhD student working with Dr Anna cox at UCLIC and associated with the CHI+MED project, gave a talk on 20 October 2011 at YDS2011 (York Doctoral Symposium on Computer Science) about her analysis of digit distribution as it relates to number entry in medical devices.
She demonstrates in the video below that the distribution of digits used in infusion tasks does not follow Benford’s Law. She goes on to show that the distribution differs depending on which ward the infusion pump is used on and considers how we might use this knowledge to design infusion pumps that better support the tasks of medical staff.
