虚拟家电技术研究

针对网络家电功能不易扩展的问题,提出了基于计算机(或嵌入式计算机)中间软件的虚拟家电技术方案。通过归纳白色家电(小家电)基本的功能建立网络家电功能向量表。分析网络家电功能向量表,使表中的功能和网络虚拟数字/模拟通向相对应。设计对家庭网络虚拟数字/模拟通道读写的应用层协议。通过建立虚拟家电的实例表明:虚拟家电对硬件资源要求少,更易于与人工智能方法结合,有利于在家电信息互联基础上的家庭能量和物质资源的整合。     

Thermal comfort and use of thermostats in Finnish homes and offices

Thermal comfort and use of thermostats in homes and office rooms were examined by a quantitative interview survey with a nationally representative sample in Finland. The total number of respondents was 3094. The results show that thermal comfort levels are lower in offices than in homes. People feel cold and hot more often in offices than in homes during both the winter and summer seasons. The perceived control over room temperature is remarkably low in offices. Higher thermal comfort levels and perceived control in homes are supported by greater adaptive opportunities. In offices people have fewer opportunities to control the thermal environment, people deal worse with thermostats, and people have lower opportunities to adapt to different thermal environments.

A DCT-based ownership identification method with gray-level and colorful signatures

In this paper, we propose an ownership identification method based on discrete cosine transformation (DCT). The copyright owner can select a gray-level or colorful image to be an ownership statement, which is used as a claim to the ownership of his/her work. Unlike traditional watermarking schemes, the ownership statement is not embedded into the image to be protected. Instead, our method will construct an ownership share for the author according to the feature of the original image and the ownership statement. The feature map of the original image is composed of DC coefficients of different DCT blocks. When piracy happens, the author can show his ownership share to reveal the ownership statement to prove his/her copyright. Note that the size of the ownership statement is not restricted to being smaller than that of the host image. In addition, multiple ownership statements can be registered for a single image without destroying each other. The experimental results will show the robustness of our scheme against several common attacks. Finally, we will give some discussions and comparisons with other researchers’ study.

Intelligent System for Adapting to a User’s Characteristics

In this paper, we propose an intelligent system that adapts itself to a user’s characteristics or habits. The proposed intelligent system is composed of two Learning Vector Quantisation (LVQ) networks, commonly used in the fields of pattern recognition and signal processing. From the external condition of the plant, the first LVQ network learns to recognise the pattern of the sensed signal, and then aids the second LVQ to learn the user’s characteristics or habits so as to automatically produce the user’s favoured output. To verify the usefulness of the proposed method, we simulated and experimented with a variable illuminator. Both simulation and experimental results showed that the proposed intelligent system learns to automatically produce the illuminator output that the user most favours for the circumstances.     

Development and evaluation of an affordable lift device to reduce musculo-skeletal injuries among home support workers

Home support workers (HSWs) work in clients' homes assisting with rehabilitation and activities of daily living. Like all health-care professionals, HSWs are at an increased risk for developing back injuries. Lift devices have been shown to reduce injuries to the worker. Presently, there are few lifting devices for home use that cost under $4000 CDN. Our study involved designing a safe and affordable lift device (retail cost under $2000 CDN) to be used by HSWs in the home and evaluating it in a typical bathroom. Thirty-eight HSWs and three seniors evaluated the BCIT lift, a commercially available lift (BHM Medical Inc.) and the manual method of transfer and lift. Results indicated that the BCIT lift was an improvement over the manual method of transferring, and approximated the more expensive, automatic lift in terms of perceived exertion, ease of use and safety. Feedback provided to the researchers has been incorporated into a new, ergonomically sound and marketable lift device.     

Investigating design issues in household environments

This paper argues that the current involvement of end users in the design of technological artefacts is too superficial. It is common to involve people in requirements generation, but rarely in product inception or design. A study is reported involving five households in central Scotland, who were each visited on three occasions, using a new investigative framework. Illustrative examples are provided of the strengths and weaknesses of the methods used. Despite the latter, it is demonstrated that the general public can both generate and critique design ideas and that valuable contributions to understanding people's relationships with technologies can be expected both from children and from the elderly.
