2. Introduction • Longer life increases the number of people with loss of autonomy1 • The use of ICT’s2 –tactile and speech modalities3- can improve the well being of older people at home • Need to observe and question, in an ambient environment (MIB- smart home of Blagnac, France) • how older people take control of ICT ‘s? • what their representations and intentions about ICT’s are? 1Chappell, N.L., Cooke, H.A.: Age Related Disabilities - Aging and Quality of Life.

9. Quantitative results (1/2) A great majority of participants change positively their opinions about ICT  need to demonstrate the potential benefit of these technologies The change of opinion about technologies ICCHP 2016 - Multidimensional observation methodology for the elderly in an ambient digital environment - Toulouse, FRANCE

10. Quantitative results (2/2) • Preference interaction mode • Voice input Tactile ICCHP 2016 - Multidimensional observation methodology for the elderly in an ambient digital environment - Toulouse, FRANCE

11. Qualitative results (1/2) • High importance of the speech voice of the smart house, perceived as: • An incarnation of the smart home • a reassuring presence “the voice tranquilizes me, it reassures me”; “I am most impressed, amazed by the voice” • a strong element of comfort “the voice of the house helped me, it's great” • Speech input • A natural way to interact with the smart house • Several modes of voice commands have been observed : keywords or continuous speech) • Commands are also contextualized “light on” and concerns the smart home objects “TV select the chain 2” ICCHP 2016 - Multidimensional observation methodology for the elderly in an ambient digital environment - Toulouse, FRANCE

12. Qualitative results (2/2) • Importance of redundancy of several modes of interactions (tactile and vocal) • Offering the choice of interaction mode for interacting with the objects of the smart house ; “voice command offer free hand to do anything” • Possibility of giving multimodal commands ICCHP 2016 - Multidimensional observation methodology for the elderly in an ambient digital environment - Toulouse, FRANCE

13. Conclusion and future work • Participants express a fear about the cost of the equipment • Participants wish to stay at home as long as possible but do not anticipate any loss of autonomy • Heterogeneity of representations and behaviours and no influence of the age (> 60) on the results • necessity to individualize and adapt smart cities to very different needs • Future works : • The experiment is carried on to sharpen the results and merge them with the social-cultural and health profiles of the participants. • Extension of the results about 150 participants ICCHP 2016 - Multidimensional observation methodology for the elderly in an ambient digital environment - Toulouse, FRANCE
