Loneliness and social isolation in the elderly are major problems in elderly care. In many European countries more than half of the people over the age of 75 live alone and 12% of older people feel trapped in their own homesResearch has shown that being alone in old age will often lead to social deprivation, low self-esteem or physical inability and also that there is a strong correlation between social isolation and poor health. Join-In aims at counteracting loneliness in the elderly by providing a methodology and technologies for elderly persons to participate in social activities and to make them part of society. By offering useful activities that encourage communication we aim to help the elderly to meet and exchange with others.
