eople suffering of cognitive impairments in Quebec Alzheimer disease : 5.1% of people over 65 years old Head trauma : 3000 new cases each yearSchizophrenia : 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.

Objectives

Provide adapted and personalized environmental cues to

Foster the autonomy of cognitively impaired people at homeLessen risks and hazards at home

Pervasive computingTangible user interfaces

Keep ensuring continuous cognitive assistance outside people’s home

Mobile computingLocation-based services

Help relatives and caregivers to keep in touch at distance with cognitively impaired people

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.

Cognitive deficits Attention

Memory

Planing

Initiation

Attention deficitsD

uring 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.

Planning deficitsT

he planning deficit leads to the difficulty to perform an appropriate sequence of actions in order to achieve a goal.

Memory deficitsT

he 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 off when the object is too far away.

The lamp turns on to highlight the searched object (red book)

Initiation deficitsThe 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.

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.
