The final result of the graduation project is the Wijstijd. It focuses on the problems surrounding time orientation for people with dementia. The Wijstijd is a clock which visually links your appointments for today to the current time. It consists of an analogue clock with a screen underneath. Different functions support the user and can be adjusted to fit their needs in their current situation. Here the main functions of the Wijstijd will be elaborated.

The Wijstijd will give an overview of the coming appointments by means of making the appointment times light up at the corresponding times on the clock face. This allows for a quick overview to support the understanding of the relation between the current time and the upcoming appointments.

Due to dementia being a progressive disease, the Wijstijd can be adjusted to the different needs a person with dementia faces. Ideally the Wijstijd is introduced in the early stage , or even before diagnoses, of dementia. Here the Wijstijd will function as a daily overview, where the screen will show the next appointment and give an overview when you come closer. When dementia progresses, the information on the screen can be adjusted. It can show an overview

of the daily planning, such as meals and visits, or show the main activity for the day and the corresponding person that will be visiting. It can even go down to the level of only showing the sun or moon supporting the textual information on which day and part of day it is.

To address the problem of people who do look at their agenda, but still forget to leave on time for their appointment, a notification is added. The notification will sound when it is almost time to leave for the appointment.

To input appointments, the Wijstijd is supported by an online calendar. This allows the family, especially in cases where the person with dementia lives alone, to input the appointments and keep track of the calendar from a distance.

To make it even easier to quickly input appointments, a key is added to the Wijstijd. This physical key allows a caregiver to activate the voice controlled function. This function allows them to input appointments. Using a key makes sure that when the person with dementia is unable to use this voice controlled function, without the key they can’t accidentally change or remove appointments.

The frame and clock face of the Wijstijd stayed close to an old clock, which would be better recognisable for people with dementia. To clarify the current hour, the hour clock-hand has a coloured circle attached to it. This feature addresses the problem of confusing the hour- and minute- hand with each other.

Within the development process of the Wijstijd, the users played an important role. They were involved in the preparation, by means of a probe study, focus group session, interviews and a feedback session on the first prototypes. During the rest of the graduation project, the users were involved by means of another feedback session on the prototype from the preparation, an online questionnaire and a clock test. Lastly, the Wijstijd was deployed into the homes of three different couples for the duration of one week each. Additionally, research papers were implemented throughout the process to support the findings that came from the user involvement.

Especially the deployment was an important part of the process of the Wijstijd. A deployment allows for richer feedback on the prototype and an insight into whether or not the user will actually use the product. It showed that the overall function of the Wijstijd was well received and showed potential for being supportive when being used over a longer period of time.

If you want to know more about the Wijstijd and the development and business side of the project, I recommend reading the final report.

For an overview of what I learned and how this connects to my overall growth, I recommend reading the overall growth page.

During the project, I noticed that the large user involvement helped throughout the process. Nevertheless, I also noted that I have to be careful when having such an elaborate involvement with the users to keep looking at the broader picture. Problems that one person you talk to experiences may or may not be relevant for a larger group of people. Therefore it is important to relate the insights gathered from one user to a bigger group or research about the subject.

During the project, different methods were used to gather insights from the users. A probe study, workshop, semi-structured interviews and a Deployment all were part of this. With the interviews, an interesting aspect surfaced on the aspect of introducing a persona in relation to the product. This persona may help with projecting the problems someone faces onto someone else, to make the conversation less invasive into their own privacy. I find it interesting to see how this could possibly help with further user involvement.

Lastly, the Wijstijd was deployed to test how it will fit into a person’s everyday life. The deployment helped with gaining richer insights, but also showed the importance of the aesthetics of a product. Here especially the size greatly seemed to influence a user’s perception on the functionality of the product. This is an aspect to take into account when building prototypes.
