Watching TV not only provides news information but also gives an opportunity for different generations to communicate. With the proliferation of smartphones, PC, and the Internet, increase the opportunities for communication in front of the television is also likely to diminish. This has led to some problems further from face-to-face such as a lack of self-control and insufficient development of communication skills. This paper proposes a TV-watching companion robot with open-domain chat ability. The robot contains two modes: TV-watching mode and conversation mode. In TV-watching mode, the robot first extracts keywords from the TV program and then generates the disclosure utterances based on the extracted keywords as if enjoying the TV program. In the conversation mode, the robot generates question utterances with keywords in the same way and then employs a topics-based dialog management method consisting of multiple dialog engines for rich conversations related to the TV program. We conduct the initial experiments and the result shows that all participants from the three groups enjoyed talking with the robot, and the question about their interests in the robot was rated 6.5/7-levels. This indicates that the proposed conversational features of TV-watching Companion Robot have the potential to make our daily lives more enjoyable. Under the analysis of the initial experiments, we achieve further experiments with more participants by dividing them into two groups: a control group without a robot and an intervention group with a robot. The results show that people prefer to talk to robots because the robot will bring more enjoyable, relaxed, and interesting., Comment: 15 pages, 3 figures, 11 tables

Some elderly care homes attempt to remedy the shortage of skilled caregivers and provide long-term care for the elderly residents, by enhancing the management of the care support system with the aid of smart devices such as mobile phones and tablets. Since mobile phones and tablets lack the flexibility required for laborious elderly care work, smart AR glasses have already been considered. Although lightweight smart AR devices with a transparent display are more convenient and responsive in an elderly care workplace, fetching data from the server through the Internet results in network congestion not to mention the limited display area. To devise portable smart AR devices that operate smoothly, we first present a no keep alive Internet required smart hands-free elderly care support system that employs smart glasses with facial recognition and text-to-speech synthesis technologies. Our support system utilizes automatic lightweight facial recognition to identify residents, and information about each resident in question can be obtained hands free link with a local database. Moreover, a resident information can be displayed on just a portion of the AR smart glasses on the spot. Due to the limited size of the display area, it cannot show all the necessary information. We exploit synthesized voices in the system to read out the elderly care related information. By using the support system, caregivers can gain an understanding of each resident condition immediately, instead of having to devote considerable time in advance in obtaining the complete information of all elderly residents. Our lightweight facial recognition model achieved high accuracy with fewer model parameters than current state-of-the-art methods. The validation rate of our facial recognition system was 99.3% or higher with the false accept rate of 0.001, and caregivers rated the acceptability at 3.6 (5 levels) or higher., Comment: 9 pages, 6 figures, 5 tables
