"I have a long-standing interest in happiness and quality of life, including aspects related to aging. I've done a lot of research on how to measure quality of life, and on its determinants. Sometimes, I find, surprisingly small changes can have a major positive impact on one's quality of life, while major events, such as becoming chronically ill, can have a surprisingly small impact. Perhaps exactly because some of these effects and non-effects are surprising, people often mispredict what will make them happy and unhappy and fail to take the actions that would most improve their quality of life. All of these issues are important when it comes to technology aimed at the elderly. To know whether a technology is beneficial we need to be able to measure its impact on quality of life. And to understand why people do or do not make use of available technologies, we need to understand their intuitions regarding what types of technologies will improve their quality of life."
