Caterpillar Smart Pill Organiser - Report

Medication errors and poor medication adherence lead to higher risks to the patient as well as increased cost to the health care sector.

Various solutions such as smart pillboxes have been developed to combat this problem. However, current smart pillboxes only use simple techniques such as fixed timed alarms and do not take into account the user habits.

A more flexible solution is proposed by utilising machine learning and a customised pillbox to introduce adaptive reminders to the patient’s schedule

• When time reaches, emit indicator to pillbox as to which box to open next
• Once pill is taken record time taken

Example object
