Eating well is crucial to maintaining good health, especially as we age. However, many elderly people struggle to keep track of their meals or determine what is good for them. This study introduces Nutrihealth, a mobile app created to help elderly users manage their diets using persuasive design techniques.
Nutrihealth is a mobile app that helps seniors
- Calculate their Body Mass Index (BMI)
- Track their daily calorie intake
- Get food suggestions based on their needs
But what makes Nutrihealth special is how it’s designed to encourage users to stay healthy, not just inform them. That’s where persuasive design comes in.
Persuasive design is a way of designing technology that gently guides people to make better choices without forcing them. It uses strategies that motivate and influence behavior.
Nutrihealth uses these techniques:
- Reduction: simplifies tasks to make them easier to do
- Tunneling: guides users step by step
- Tailoring: gives personalized suggestions
- Self-monitoring: shows users their progress
- Attractiveness: uses a clean, senior-friendly interface
- Trustworthiness: provides reliable and clear information
- Readability & terminology: uses simple language and clear visuals
These elements help seniors stay engaged, understand the app easily, and feel motivated to improve their diet. As people age, they may face challenges like memory issues, lower tech confidence, or reduced eyesight. Persuasive design helps by :
- Making technology more approachable
- Encouraging positive habits without feeling overwhelmed
- Giving feedback that builds confidence and motivation
In short, it turns an app into a gentle coach instead of just a tool. Nine seniors in Malaysia, aged 50 and above, used the app for three days. They logged their meals, got daily calorie updates, and received food suggestions. Afterward, they answered a survey and were interviewed.
- Easy to use: Most said the app was simple and not confusing
- Helpful info: It gave useful feedback about their health
- Family support: Their families encouraged them to use it
- Willing to continue: All were open to using it again in the future
Some faced technical issues like older phones or limited food options in the app’s database, but the overall experience was positive.
Nutrihealth shows that with thoughtful, persuasive design, mobile apps can truly support older adults in living healthier lives. The app didn’t just inform. It inspired users to take action. With more development, like a larger food database and wider testing, Nutrihealth could become a valuable tool for elderly care everywhere.
