Usability of a tablet computer designed for older adults: a qualitative approach based on an intra-hospital living-lab for healthcare
ABSTRACT
Background:
Usability is the keystone in the evolution of tablet technology in healthcare. The Ardoiz® tablet has been designed with a simplified interface for older adults.
Objective:
To assess the perceived usability and satisfaction of the Ardoiz® tablet.
Methods:
We conducted a mixed methods with cross-sectional study using System Usability Scale (SUS), satisfaction score and workshops, including geriatric patients, healthcare professional and caregivers.
Results:
Between September 25, 2019 and March 11, 2020, 58 participants were included in a cross-sectional study (including 38 patients, mean ±SD 85±6 years, 66% women), 26 in workshops (including 5 patients, mean ±SD 86.4±2.9, 40% women). The SUS was 74±12/100, the satisfaction score was 2.8±0.9/4, with 59% of satisfied participants with the use of Ardoiz® pads. The intent to acquire remained low with 18% (n=6) of participants who would be interested in acquiring the tablet. This tablet computer seemed to be difficult to use by geriatric patients and healthcare professionals, mainly because of its complex homepage. Nevertheless, former caregivers and healthcare professionals thought that the tablet could be of great interest to hospitals for leisure and medical use. The main feedback in order to improve the tablet is to simplify the home page with fewer and more static icons (without switching).
Conclusions:
Notwithstanding the usability of the tablet, the intent to acquire of Ardoiz® tablet remained low. The interface should be simplified for older adults in order to improve usability and adherence. Clinical Trial: NCT04091152
