Intelligent environment

Abstract: While intelligent environments are often cited as a reason for doing work on visual person-tracking, really making an intelligent environment exposes many real-world problems in visual tracking that must be solved to make the technology practical. In the context of our EasyLiving project in intelligent environments, we created a practical person-tracking system that solves most of the real-world problems. It uses two sets of color stereo cameras for tracking multiple people during live demonstrations in a living room. The stereo images are used for locating people, and the color images are used for maintaining their identities. The system runs quickly enough to make the room feel responsive, and it tracks multiple people standing, walking, sitting, occluding, and entering and leaving the space.

Abstract: In this paper, we review the background and state-of-the-art of the narrow-band Internet of Things (NB-IoT). We first introduce NB-IoT general background, development history, and standardization. Then, we present NB-IoT features through the review of current national and international studies on NB-IoT technology, where we focus on basic theories and key technologies, i.e., connection count analysis theory, delay analysis theory, coverage enhancement mechanism, ultra-low power consumption technology, and coupling relationship between signaling and data. Subsequently, we compare several performances of NB-IoT and other wireless and mobile communication technologies in aspects of latency, security, availability, data transmission rate, energy consumption, spectral efficiency, and coverage area. Moreover, we analyze five intelligent applications of NB-IoT, including smart cities, smart buildings, intelligent environment monitoring, intelligent user services, and smart metering. Finally, we summarize security requirements of NB-IoT, which need to be solved urgently. These discussions aim to provide a comprehensive overview of NB-IoT, which can help readers to understand clearly the scientific problems and future research directions of NB-IoT.

Abstract: This paper describes our concept of Intelligent Space. Intelligent Spaces are rooms or areas that are equipped with sensors, which enable the spaces to perceive and understand what is happening in them. With such features, people or systems in the Intelligent Space can use additional functions that are afforded by the space. This research field itself is not particularly related to robotics, but we believe robots under Intelligent Spaces have many interesting features. Intelligent Spaces are expected to have a broad range of applications such as in homes, offices, factories, etc. Thus, we can consider that a robot, which will be used in our general living environment, is related to the concept of Intelligent Space. Several applications of Intelligent Space are shown in this paper with descriptions.

Abstract: Michael C. Mozer, University of Colorado What will the home of the future look like? One popular vision is that household devices-appliances, entertainment centers, phones, thermostats, lights-will be endowed with microprocessors that allow the devices to communicate with one another and with the home’s inhabitants. The dishwasher can ask the water heater whether the water temperature is adequate; inhabitants can telephone home and remotely instruct the VCR to record a favonte show; the TV could select news stones of special interest to the inhabitant; the stereo might lower its volume when the phone rings; and the clothes dryer might make an announcement over an intercom system when it has completed its cycle.
