This study developed a fall detection system for elderly people in a nursing home and investigated their acceptance of it. The system obtained their positions and heights from range sensors and used that information to correctly detect 89.5% of the falls based on data where the elderly crouched in a ...

This paper proposes a method that estimates customer interests by identifying a set of areas at which a customer has stopped in our experimental shop environment and recommends items through robots located on the shop's shelves. We experimentally verified that our method changed customer behaviors. The results show that the ...

When a human user interacts with an adaptive agent to achieve human-agent collaboration, active adaptation is considered to be one of the critical characteristics of the agent. In order to investigate the principal features of active adaptation, we developed a human-agent collaborative experimental environment called WAITER (waiter agent interactive training ...

By applying network robot technologies, recommendation methods from E-Commerce are incorporated in a retail shop in the real world. We constructed an experimental shop environment where communication robots recommend specific items to the customers according to their purchasing behavior as observed by networked sensors. A recommendation scenario is implemented with ...

The construction of real-world knowledge is required if we are to understand real-world events that occur in a networked sensor environment. Since it is difficult to select suitable 'events' for recognition in a sensor environment a priori, we propose an incremental model for constructing real-world knowledge. Labeling is the central ...

Active interface is one of critical characteristics of agents who have to interact with human users to achieve human-agent collaboration. This characteristic is especially important in beginning phase of human-agent interaction when an ordinary human user begins to interact with an adaptive autonomous agent. In order to investigate principal characteristics ...

The characteristic task of service robots that can interact with humans is to achieve human-robot collaboration. Mutual adaptation is considered to be an important characteristic of robots, required for carrying out such collaborative tasks. Here, we introduce the concept of mutual adaptation, propose a learning model, and describe an experimental ...

The Object-Blog service application automatically converts raw sensor data to environment-generated content (EGC), including texts, graphs, and figures. This conversion facilitates data searching and browsing. Generated content can serve several purposes, including memory aids, security, and communication media. In Object-Blog, personified objects automatically post entries to a weblog about sensor ...

In this paper, we propose a framework for personal agents that supports inter-personal information exchange and sharing. The framework offers a repository-centered architecture in which a user can store information resources and annotations. On this framework, applications work collaboratively with the help of the event notification mechanism. The personal agent ...
