Dementia is a growing problem in today’s society. Life expectancies increase, while the population is skewing towards older age groups due to reduced birth rates. Dementia resulting from diseases such as Alzheimer’s disease becomes much more likely as age increases. These factors combined means that the amount of people with dementia is increasing constantly.
This thesis looks at the automated generation of process models, which are detailed instruction sets for cooking tasks sourced from freely available cooking recipes. The process models would be used in an ambient assisted living environment to aid the independent functioning of people with dementia. This would also lessen the workload of caregivers, while also providing some mental and physical exercise for the dementia sufferer.
A process model was created by hand as a simulation of the automated process. This process model was then validated and used as the instruction set for user tests with dementia patients in a cooking task. The generated instructions were relayed with verbal prompts in a controlled environment. Tests were recorded and transcribed. Test results were used to further assess the validity of the simulated process model conversion.
Results were used in determining issues that should be acknowledged during the development of an automated process model generation system. A basic architecture for the system is discussed.
