During the period from March 2015 to September 2015 field trials were carried out in Italy and in the Netherlands. The main objective of the test was to have feedback on the functionality of the system and to verify its usability.
Eighteen older people, selected according to the project inclusion criteria, were involved in this activity; each of them tested the ChefMyself system for a period of two months.
The mean age of the participants was 64 years and they were quite heterogeneous regarding level of education and working status. Among the group of users there was full time active workers and retired persons. Thirteen participants were women and five were men.
All the users appreciated the possibility given by ChefMyself to save time during cooking, so that it could be dedicated to other activities and the support to maintain healthy eating habits. The possibility to have nutritional details (in term of calories, lipids proteins etc..) of the meal was one of the most appreciated characteristics. The overall impression was that is necessary to improve the quantity and the diversity of the recipes.
The different skills on technology use influenced the expectations on the system functionality, therefore usability was quite different. People with a larger experience asked for a more complex system and functions, while those with less confidence were afraid of not being able to use it correctly. However all of them evaluated positively the usability of the system.
When they were asked about their interest in buying the ChefMyself system, most of the answers were positive, but almost all of them were available to spend a sum of money lower than the proposed price of the system.
Among the group of users there was full time active workers and retired persons.
