We address the problem of designing a conversational avatar capable of a sequence of casual conversations with older adults. Users at risk of loneliness, social anxiety or a sense of ennui may benefit from practicing such conversations in private, at their convenience. We describe an automatic spoken dialogue manager for LISSA, an on-screen virtual agent that can keep older users involved in conversations over several sessions, each lasting 10-20 minutes. The idea behind LISSA is to improve users' communication skills by providing feedback on their non-verbal behavior at certain points in the course of the conversations. In this paper, we analyze the dialogues collected from the first session between LISSA and each of 8 participants. We examine the quality of the conversations by comparing the transcripts with those collected in a WOZ setting. LISSA's contributions to the conversations were judged by research assistants who rated the extent to which the contributions were "natural", "on track", "encouraging", "understanding", "relevant", and "polite". The results show that the automatic dialogue manager was able to handle conversation with the users smoothly and naturally.
Another approach that has proved effective in ameliorating loneliness and depression in older people is reminiscence therapy @cite_8 . A pilot study aimed at implementing a conversational agent that collects and organizes memories and stories in an engaging manner is reported in @cite_10 . The authors suggest that a successful companionable agent needs to possess not only a model of conversation and of reminiscence, but also generic knowledge about events, habits, values, relationships, etc., to enable it to respond meaningfully to reminiscences. Robotic pets are another interesting technology offered for alleviating loneliness in older people; such pets react to user speech and petting by producing sounds and eye and body movements. Studies @cite_17 show that such interactions can improve users' communication and interaction skills.

In this paper we describe the requirements and early system design for a smart conversational agent that can assist older adults in the reminiscence process. The practice of reminiscence has well documented benefits for the mental, social and emotional well-being of older adults. However, the technology support, valuable in many different ways, is still limited in terms of need of co-located human presence, data collection capabilities, and ability to support sustained engagement, thus missing key opportunities to improve care practices, facilitate social interactions, and bring the reminiscence practice closer to those with less opportunities to engage in co-located sessions with a (trained) companion. We discuss conversational agents and cognitive services as the platform for building the next generation of reminiscence applications, and introduce the concept application of a smart reminiscence agent. Lack of companionship, loneliness, and social isolation are often experienced by older adults diagnosed with clinical depression living independently within the community. Socially assistive robots (SARs), a relatively new concept within recreational therapy, may be one treatment modality that can address each one of these concerns. This exploratory study consisted of interviews with community mental health professionals, including a recreational therapist, to determine if they perceived SARs as an appropriate interdisciplinary clinical intervention for older adults diagnosed with clinical depression. Results indicated that SARs, especially those which can provide companionship and social interaction similar to animal assisted therapy, are an appropriate interdisciplinary intervention for this population and may have an impact on improving overall quality of life by decreasing loneliness and social isolation associated with clinical depression. Introduction Animal-assisted therapy is gaining popularity as part of therapeutic activities for older adults in many long-term care facilities. However, concerns about dog bites, allergic responses to pets, disease, and insufficient available resources to care for a real pet have led to many residential care facilities to ban this therapy. There are situations where a substitute artificial companion, such as robotic pet, may serve as a better alternative. Methods This pilot study used a one-group pre- and posttest design to evaluate the effect of a robot-assisted therapy for older adults. Sixteen eligible participants participated in the study and received a group robot-assisted therapy using a seal-like robot pet for 30 minutes twice a week for 4 weeks. All participants received assessments of their communication and interaction skills using the Assessment of Communication and Interaction Skills (ACIS-C) and activity participation using the Activity Participation Scale at baseline and at week 4. Results A total of 12 participants completed the study. Wilcoxon signed rank test showed that participants' communication and interaction skills (z = −2.94, P = 0.003) and activity participation (z = −2.66, P = 0.008) were significantly improved after receiving 4-week robot-assisted therapy. Discussion By interacting with a robot pet, such as Paro, the communication, interaction skills, and activity participation of the older adults can be improved. The robot-assisted therapy can be provided as a routine activity program and has the potential to improve social health of older adults in residential care facilities. The impact of the world-wide ageing population has commenced with respect to society in developed countries. Several researchers focused on exploring new methods to improve the quality of life of elderly individuals by allowing them to remain independent and healthy to the maximum possible extent. For example, new walking aids are designed to allow elderly individuals to remain mobile in a safe manner because the importance of walking is well-known. The aim of the present study involves designing a humanoid robot guide as a walking trainer for elderly individuals. It is hypothesized that the same service robot provides an assistive and social contribution with respect to interaction between elderly users by motivating them to walk more and simultaneously provides assistance, such as physical assistance and gait monitoring, while walking. This study includes a detailed statement of the research problem as well as a literature review of existing studies related to walking companion robots. A user-centred design approach is adopted to report the results of the current first feasibility study by using a commercially available humanoid robot known as Pepper developed by Softbank-Aldebaran. A quantitative questionnaire was used to investigate all elements that assess intrinsic motivation in users while performing a given activity. Conversely, basic gait data were acquired through a video analysis to test the capability of the robot to modify the gait of human users. The results in terms of the feedback received from elderly subjects and the literature review improve the design of the walking trainer for elderly individuals.
