• Technologies matching the needs of
• lder adults with cognitive

impairment

• Provide therapy and cognitive

prothesis

• Increase social link
• Train carers and alleviate their

burden

• Facilitate life at home

Our aims

Social robots: state of the art

• Robots for older adults:

– Assistant, companion

(Sharkey and Sharkey, 2010)

End-users needs

• Difficulties: memory impairment, somatic diseases &

loneliness

• Interest for services: cognitive stimulation,

assistance in finding small items, appointement reminder, visiocall

• No expression of need for help in ADL
• Fear of stigmatization and intrusion (Valkila et al 2009)
• 22 older adults
• MMSE = 19-30
• Age = 66-88
• Questionnaires

Objective and method

• How did 20 older and 23 young adults perceive

affects from expressions of the Nabaztag?

• 27 expressions of Nabaztag
• 3 colours: green, blue, and red
• 3 ear positions: horizontal, vertical and asymmetric
• 3 levels of speed of light blinking: rapid, slow and

continuous)

Procedure

• Subjects categorized each of the 27 expressions of

Nabaztag into one of the 8 affects in term of adjective (surprised, enthusiastic, joyful, calm, inactive, bored, sad and frustrated).

• These items were chosen

based on the circumplex model of affects

Russell, J.A.,1980. A circumplex model of affect. Journal of Personality and Social Psychology: 39, 1161–1178

Colours : perception of affects

10 20 30 40 50 surprised enthusiastic joyful calm * inactive bored sad frustrated * blue red green 10 20 30 40 50 surprised enthusiastic * joyful * calm * inactive bored * sad * frustrated * blue red green

Young adults Older adults

• For the younger adults, colors were useful clues to

help interpret affects.

• Blue mostly related to calmness & red to frustration

Ear position: perception of affects

10 20 30 40 50 60 surprised * enthusiastic * joyful * calm * inactive bored * sad frustrated vertical asymetric horizontal 10 20 30 40 50 surprised enthusiastic * joyful * calm inactive bored sad * frustrated vertical asymetric horizontal

Young adults Older adults

• The older adults used ear positions as clues to

interpret affects.

• Vertical ear position mostly related to positive affects,

such as joy and enthusiasm.

• Older adult’s interaction with a robot, a virtual agent and a laptop

while playing a game of trivia?

• 19 older adults’ preferences: Laptop>robot>avatar

Discussion

• Acceptance and use
• Interactions with robots

Use

• Tailor robots and services to end-users needs
• Develop tools to test end-users’acceptance,

pleasure and engagement

• Test at home and long term experience
• Respect confidentiality and consent
• Ensure liability and safety of use
• Ensure ethical reflexion

– Safety in ADL versus intrusion – Companion versus loss of humanity – Innovation versus stigmatization

Main points: end-users and robots
