Abstract
Obesity is considered as the main health issue worldwide. The obesity rate within Saudi’s citizens is rising alarmingly. The Internet of Things (IoT)-enabled mobile apps can assist obese Saudi users in losing weight via collecting sensitive personal information and then providing accurate and personalized weight loss advice. These data can be collected using embedded IoT devices in a smartphone. However, these IoT-enabled apps should be usable and able to provide data security and user privacy protection. This paper aims to continue our usability study for two Arabic weight loss IoT-enabled apps by performing a qualitative analysis for them. It discusses users’ and health professionals’ feedbacks, concerns and suggestions. Based on the analysis, a comprehensive usability guideline for developing a new Arabic weight loss IoT-enabled app for obese Saudi users is provided.
Highlights
Obesity can be defined as an act that stores additional energy within a human body in the form of fat [1]
A recent study states that around 13% of the world population suffers from obesity, and almost 40% of the world population is considered to be overweight [2]
The Kingdom of Saudi Arabia suffers from the obesity threat as more than 35% of Saudi citizens are experiencing this issue [3]
Summary
Obesity can be defined as an act that stores additional energy within a human body in the form of fat [1]. Weight loss IoT-enabled apps, can have unique features that motivate obese users to change their lifestyle and lose weight [5]. Developing an advanced Arabic weight loss IoT-enabled app contributing to treat and stop obesity among Saudi citizens is seen as important. We identified the most important features which can motivate users to be active to overcome obesity [8]. A usability testing for two Arabic weight loss apps (Twazon and Aded Surat) which are used by obese Saudi users was conducted with 26 users to detriment their level of usability which was low based on the quantitative results [10, 11]
