We have been studying Cloud HNS, which is a new type of home network system using the cloud. In this paper, we consider value-added services that can be provided by introducing a smart TV as an appliance of Cloud HNS. First, we discuss requirements, role and benefits of a smart TV in the integration with Cloud HNS. Then, we propose concrete scenarios of value-added services achieved by the integration.
We propose a super-resolution system for high-resolution displays that decomposes the input image into a structure component and a texture component using total variation regularization. The structure component is processed using a shock filter and the texture component is processed by a pulse enhancement filter. This system requires less computational time compared with learning-based systems and...
We have been studying log contexts using large-scale house log collected in home network system (HNS). A log context is defined with both the current and past situations of a house, where the current situation is characterized by the current status of an appliance (or a sensor), while the past situations are derived from the house log. In this paper, we propose context-aware services for smart TVs...
This paper proposes a super-resolution system for 4K-HDTV. In the basic super-resolution system, the input image is decomposed by the total variation filter into structure and texture components. The structure components are enhanced by the shock filter whereas the texture components are enhanced by the pulse enhancement filter. Two important additional functions are included in the proposed system:...
Artificial three-dimensional (3D) video technology has generated significant interest in recent years. However, there are concerns about side effects such as eye strain that may result from viewing 3D video images. This visual fatigue is assumed to be related to a mismatch between convergence distance and focal length that occurs while viewing 3D content. In this study, we investigated the relationship...
In this paper, we present a home sleep care system to monitor function of activity measurement and sleeping position estimation via vision-based algorithms. The outcomes are integrated in a telecare middleware with a hierarchical software stack and visualized by a structural subsystem. Since smart TVs play an important role in home tele-healthcare system, we centralize and display additional sleep...
In this paper, we propose a system to superpose information of web services into living space. The system is controlled by natural actions which are gestures and voice in order to simple control apparatus. The system is assembled by three major modules which the sound recognition, the gesture recognition and a projector. We describe the entire process, the implementation and the evaluation of a prototype...
Factors to understand properly the biological influences caused by 3D images are discussed based on the physiological background, especially focused on the conflict between lens accommodation and vergence eye movement.
The synchronized presentation of tactile information along with audio and visual content can enhance viewing experience. In this paper, we propose two requirements of a Smart TV service: feasibility and flexibility. We then develop a tactile sensibility presentation service for a Smart TV that can synchronize tactile information transmitted through the Internet with a TV program broadcast digitally...
These days Web technology is applied to various CE devices, e.g., smart TVs. However, ordinary GUI is not necessarily the best option for people in some situations even with touch panels. So the need for easier-to-use products is growing. To solve this issue, this paper describes the needs for (1) choosing additional modalities dynamically based on the users' demands and (2) standard library to handle...
Increasing in the size of TV, Smart TV in connected to internet is spreading. Remote-control of TV is complicate by increase of contents. In this research, we propose a Remote Touch TV that is able to operate at a large screen intuitively. Remote Touch TV is a new remote-control method for smart TV using Remote Touch Pointing. Remote Touch Pointing set on the base point and the operating point as...
TV sets and companion devices (Smartphones, Tablets, etc.) have outgrown their original purpose and are now playing together an important role to offer the best user experience on multiple screens. However, the collaboration between TV and companion applications faces challenges that go beyond traditional single screen applications. These range from discovery, wake-up and pairing of devices, to application...
We propose a life-log aggregation system using smart TV as management hub. In this proposed system, various kinds of life-logs of family members are gathered logically and managed by functions related to smart TV. Under the management of the smart TV, the life-logs can be used by a lot of services to realize various type of personalized or family based services. We believe that this proposed system...
Hybridcast is a new service that integrates broadcast services and broadband communication services. This service has already launched in Japan. In this paper, we describe overall system of Hybridcast service, especially the mobile device coordinated system and the application of the system. The number of Hybridcast content is gradually increasing. For the further spread of Hybridcast content, we...
Recently, investigations on user-oriented information delivery system to support information acquisition has been actively conducted. In order to provide information retrieved from the internet, TV program and local contents, we propose an information delivery system based on Active Information Resource (AIR). This paper describes a design of AIR-based cooperation mechanism of heterogeneous contents...
