1. Please discuss how you think the perceived ease of use and usefulness may differ among the different demographics.

– Age: Age definitely affects how easily people use technology. From what I’ve seen in my workplace, older people often find new tech more complicated and are more hesitant to use it. When new technologies are introduced at work, they can be afraid at first and might take longer to learn how to use them. However, once they see how useful the technology can be, they usually come around and start using it more confidently.
– Gender: Some believe that men are generally better at technology than women because men have been more represented in tech fields than women. In the context of personal health records (PHRs) I think any users can use it as the application does not need the technical skill that much. They only need to know about the features and their function and I believe the developer aims to create the app that friendly for all genders.
– Education: Higher education often leads to better skills with technology. People with more education usually get more experience with tech tools and develop better technical skills. Those with less education might struggle more with using these tools due to less exposure and training.

2. In your experience of using e-health applications or systems, what are some external factors or variables that should be considered to extend the proposed model for assessing the intention to use the system?

In my experience, external factors that can be considered including:
– Health status and behavior: People with health problems are usually more careful about their health compared to those who are healthy. They often have regular health check-ups and screenings. E-health systems can help them by providing easy ways to schedule appointments, get reminders, and access test results.
– Digital literacy: If people are familiar and comfortable with using digital technologies, they are more likely to use e-health systems than those who are not.
