Virtual Agents as Daily Assistants for Elderly or Cognitively Impaired People

In Yaghoubzadeh et al.'s feasibility study, feedbacks were mostly positive.

“Regarding acceptance, feedbacks were mostly positive.”

In Yaghoubzadeh et al.'s feasibility study, 10 of the 11 cognitively impaired users successfully entered their appointment.

“Overall results were very encouraging: 10 of the 11 cognitively impaired users successfully entered their appointment and could spot and correct 75% of the (purposefully introduced) errors.”

In Yaghoubzadeh et al.'s feasibility study, all the elderly participants completed the task successfully and could repair about 80% of the errors introduced.

The current literature on the use of ECAs by older adults with cognitive impairment does not provide many guidelines for adapting ECA technology for this public.

It is best to confirm each bit of information individually.

“This is similar to the approach for confirmations recommended by Yaghoubzadeh et al. [8], who stated that it is best to confirm each bit of information individually.”

Several researchers have proposed to use virtual humanoid characters, called ECAs, that are able to interact with a person through verbal and nonverbal communication.

“To do this, several researchers [5, 6, 7, 8, 9] have proposed to use virtual humanoid characters, called Embodied Conversational Agents (ECAs), that are able to interact with a person through verbal and nonverbal communication.”

In Yagoubzadeh et al.'s study, subjects repaired significantly more errors in the local condition than in the global condition.

“In addition, they observed that the subjects repaired significantly more errors in the local condition than in the global condition; this improvement was much more significant in the cognitively impaired group, who performed just as well as the healthy elderly group in this condition.”
