Usability study for the design of a
communicator for ICU patients with
Most of the patients that reside in the intensive care unit experience fear, frustration
and high levels of anxiety as they are not able to communicate properly. In this sense,
the use of communication tools can be helpful to reduce the frustration levels and also,
to improve the efficiency and the speed of the communication.
The objective of this work, is to design a tool that allows solving the communication
problems that patients suffer when they are admitted in the intensive care unit.
In order to achieve the objective of this work, a qualitative study that involved interviews
with former patients, hospital staff members and family relatives was performed. Afterwards,
the design of a prototype was developed to later conduct and analyze usability evaluations
with former patients, hospital staff members and patients relatives.
The results expose that participants of the usability evaluations were able to perform
most of the tasks effectively.
