Conclusion

3. Context People suffering of cognitive impairments in Quebec
Alzheimer disease : 5.1% of people over 65 years old
Head trauma : 3000 new cases each year
Schizophrenia : 1% of the population
They would be able to stay at home
if light assistance was provided.
But healthcare resources are scarce.
So relatives have to take responsibility for care.
turns to an exhausting burden.
Hence relatives and caregivers urge for help.

4. Objectives Provide adapted and personalized environmental cues to
Foster the autonomy of cognitively impaired people at home
Lessen risks and hazards at home
Pervasive computing
Tangible user interfaces
Keep ensuring continuous cognitive assistance outside people’s home
Mobile computing
Location-based services
Help relatives and caregivers to keep in touch at distance with cognitively impaired people

14. … to smart care
Smart homes can assist cognitively impaired people and foster their autonomy.
Indeed such augmented homes can become true cognitive prostheses.
As well, smart homes can
help caregivers to grant better care
give a sense of security to residents and their relatives.

15. Middleware Spontaneous networking Heterogeneous networks
Autonomic computing
Mobile code and agents
Location and context awareness
Security and privacy

16. A Pervasive Reminder System for Smart Homes
Identification and localization of a user
Transitory coalition of devices
Pervasiveness:
Integration in a real living environment
Fluid usage
Transparent user friendly migration of sessions
Zero-configuration
Spontaneous networking and service discovery
To cope with heterogeneity of devices and hardware, networks
Keeping the system in a clean state

What are the objects involved in an activity ?
Track primitive actions
What is the user doing or wants to do ?
Plan recognition
Hierarchical models
Lattice
Assist the user
Highligth objects
Tangible user interfaces

20. Plan recognition Hierarchical models Lattice-based models
No action models

21. Personnalization
Appli de Jérémie en maîtrise

22. Cognitive deficits
Attention
Memory
Planing
Initiation

23. Attention deficits
During task completion, the person shifts her attention from the activity under progress to a stimulus causing interference.
The person demonstrates difficulty to focus on the activity to be performed and as a consequence, the current activity should be forgotten and never completed.

24. Planning deficits
The planning deficit leads to the difficulty to perform an appropriate sequence of actions in order to achieve a goal.

25. Memory deficits
The memory processes refer to information storage and retrieval.
Suffering from memory deficits could lead to difficulties to remember the activity to perform, the steps of the activity or the locations of the tools and materials involved in that activity.
Follow-me
The lamp turns on to highlight the searched object (red book)
The lamp turns off when the object is too far away.

26. Initiation deficits
The initiation deficit leads to inactive periods whereas the person is supposed to perform actions
For example, during breakfast time, standing in the kitchen for a long time could be attributed to an initiation deficit.

28. Conclusion
At the DOMUS laboratory, on-going research projects aim at building the theory and praxis of pervasive computing and tangible user interfaces (TUI) compulsory to create smart homes for cognitively impaired people.
Pervasive computing enables a seamless integration of assistance in residents’ everyday life
while TUI turn the whole house into a cognitive prosthesis.
Prototypes are used to investigate how pervasive services and TUI can support and enhance healthcare and communication between people and caregivers.
A fully-equipped experimental apartment can accommodate cognitively impaired people and their caregivers for day and night.
The middleware provides for spontaneous networking, distributed and mobile computing, and sensor networks.
Cognitive assistants use descriptions of activities of daily living to reason upon resident actions. They then rely on context awareness and TUI to interact with people.
Finally the assistance systems remotely share information with caregivers.
