Why are Ambient Assisted Living Technologies so Difficult to Develop?

I was appointed as one of the external reviewer of Jean Hallewell Haslwanter´s PhD dissertation with the title “User-Centered Development of Sensor-based Systems for Older People”. I must say that this was indeed an interesting thesis to read and I strongly recommend it for anyone who is interested in healthcare technology and user-centered design.

Ambient Assisted Living (AAL) is a technology that has been proposed to help society with problems related to an ageing population, as it could support older people to live at home instead of moving into elderly homes. However, despite the fact that many IT projects and companies have been working with the development of this technology, and large amounts have been invested in AAL, few such technologies has reached the market. In her thesis, Jean Hallewell Haslwanter addresses the issue from a user-centered design perspective and her work aims at understanding why AAL technologies have proven so difficult to develop.

The thesis has a substantial empirical contribution as it studies the development of AAL systems. One interesting finding is that the complex and multifaceted descriptions of the users fade away as the project continues, and is replaced by stereotypes of older people. Other contributions include recommendations for practitioners working with development of AAL technology.

Jean Hallewell Haslwanter’s dissertation is a monograph, but she has 13 research papers that are previously published. Many of the papers are conference papers, of which many appear in highly ranked international conferences. There are also conference papers that have been turned into journal papers.

Visualizing Financial Futures – A PhD Thesis by Susanna Heyman

Susanna Heyman did a splendid job defending her PhD thesis last week. The thesis is about visualizing financial futures. She has worked in the area of designing for people to understand how their economy will look like when they retire. Susanna Heyman had done a classical iterative design process with several interesting iterations and methods to understand the user. The methods used were both qualitative and quantitative, and in her thesis she describes how the design has evolved. In the thesis you can also find some of the dead ends and that one also run into when you do design or a creative work. This is not the conventional way of writing a thesis, but it was nice to see how non- straightforward design work can be.

I found the background section extremely interesting and well-written. People really think in old ways when it comes to understanding economy and being affected by context. The background section connected to areas of research that were unknown to me, and I’m always interested in learning new things :-). I also appreciate all kinds of research that aims at understanding people and their thinking. People are really fascinating and interesting!

The PhD contributes to a pressing issue in society, at least in Sweden. The opponent at the defence started out by telling that 50% of all women in Sweden only get the minimum retirement sum, which is not at all a lot of money. Many Swedes don’t even think about their retirement and since economy has changed, in parallel with other things such as us living longer, the budget for a retirement is much lower than it used to be. People are also very lazy and don’t find out about their retirement economy and they don’t have the Financial literacy to understand many tools. Hence Susanna Heyman’s thesis is a very important piece work and I really hope that it will be used by banks or other companies in order to make people understand their economy of me in the future.

In the morning before the defence KTH had organised seminars given by the three people on the committee and by the opponent. Their seminars were 15- 20 minutes long which sounds like quite a short period, but I really appreciate it giving short insights into different areas. It was also obvious that the members of the committee and the opponent at excellent presenters, and experts over their different fields. I really enjoyed listening to all this and I’m looking forward to listening to the opponent and the committee at next week’s PhD defence.
