# Visualisation of Information Using Patient Journey Maps for a Mobile Health Application
## 5 Prototype Development and User Evaluation
### Main Study
#### 5.4.3 Results of the Main Study
They also reported that the task/information was easy to understand and presented in a user-centred manner. All participants agreed that there was a clear distinction among the diseases through the use of colour coding; however, some participants felt that there was no semantic connection between the colours and diseases. _'I think colour helps, like when you use colour to distinguish subway lines, but I don't know if it helps much'. (P1-20s)_  
_'The different colours made it easier to distinguish, and I don't think people would know what the disease colours mean, so I think it's just right now'. (P3, 20s)_  
The participants also found it intuitive to access a detailed screen from the card-type home screen. They felt that the detailed screen of the disease was organised vertically so that the eye could follow it naturally and the desired information was displayed at the bottom. However, some subjects in their 40s to 60s felt that it was difficult to select various types of information because the information selection button was in an on/off form; however, as the information could be selected and viewed, there was a smaller scrolling burden owing to the amount of information. **Ideas for better ways to present information:** We obtained ideas for improving the prototype in terms of the information visualisation. First, several participants commented on the need to categorise recovered diseases. At present, the prototype is organised in chronological order of disease onset, which may be less important for recovered diseases; it would be more useful to view them separately or according to disease stage. _'If there are multiple disease cards that have been cured, it would be nice to be able to see only the cured ones (cured ones and those under treatment at once)'. (P15, 40-60s)_  
_'I don't think it's necessary to see a cured disease from the top'. (P5, 20s)_  
Other comments included the need for a button to reset all selections when selecting the desired information on the detail screen and the need for a keyword search feature to make it easier to find information when the amount of information becomes overwhelming. Most users found the language easy to understand, but some participants commented that some of the terms were unfamiliar; therefore, it would be preferable to have a separate explanation for medical jargon that is unfamiliar to non-medical users. _'When I look at what the doctors write, I see how it's expressed in English and how severe it is, but when I look at the diagnosis, I think it's important to change it to make it easier for us to see'. (P1, 20s)_  
_'Most of the words themselves are written in an easy way, but since it is medical information, I think there are situations where difficult terms appear. In such cases, it would be good to have additional explanations'. (P6, 20s)_  
**User needs for additional information and features:** Users across all age groups wanted to know more about their healthcare, particularly regarding medications. Participants in their 20s, who were less experienced with medical treatments, also wished to view a record and information about the medications they were taking, whereas those in their 40s to 60s wished to view information regarding drug interactions, side effects, and misuse, as well as to have the ability to set alarms to help them to remember to take their medications during treatment. The participants expressed that they would like to see features that make it easier for them to become more involved in their care, such as the ability to add their own information, reminders of doctors' appointments and treatments, integration with their prescriptions, and communication channels with their doctors. In addition to information relating directly to their illness, they wished to access personalised information to help them to manage their health on a day-to-day basis, including basic health profile information such as height and weight, preventative measures against illness, and exercise and food recommendations.
