This paper proposes a systematic approach to developing comprehensive guidelines for mobile phone user interface, and presents a case study to validate the approach. The approach applies a systematic combination of three critical factors: general usability principles, UI components and guideline properties to developing guidelines. In the case study, this factor combination approach was very effective in collecting experts’ ideas, creating guidelines and editing them. The resulting style g...

A zoomable user interface (ZUI) is a useful function to help users deal with large information spaces displayed within a screen. Although used in many applications, ZUIs have not been sufficiently studied in terms of usability. Usability problems may be more crucial for older people than younger ones. The objective of this study is to examine the effects of a combination of two zoom factors (three zoom focus methods: original-center, re-center, and aiming-point; and two zoom scales: +100% and +4...

  Residential thermostats control 9% of the total energy use in the United States and similar amounts in most developed countries; however, the details of how people use them have been largely ignored. Five parallel investigations related to the usability of residential thermostats were undertaken. No single investigation was representative of the whole population, but each gave insights into different groups or usage patterns. Personal interviews revealed widespread misunderstand...

 Many of a building’s systems, including heating, cooling, lighting and ventilation, work separately with each other as ‘isolated islands’. While separate systems do not typically work optimally in terms of total performance, integrated control has the potential to improve energy efficiency, occupant comfort and satisfaction and cost efficiency. Preceding studies also have stressed the needs for individual control and usability in order to achieve occupant satisfaction. Fi...

  Residential thermostats control a substantial portion of both fuel and electrical energy—9% of the total energy consumption in the U.S. Consumers install programmable thermostats to save energy, yet numerous recent studies found that homes with programmable thermostats can use more energy than those controlled manually depending on how—or if—they are used. At the same time, thermostats are undergoing a dramatic increase in capability and features, including control ...

 This paper presents and evaluates two current advancements of collaborative technologies for architectural design. The paper focuses on technologies that support synchronous design collaboration, in particular, 3D virtual worlds for supporting remote design collaboration, and tangible user interfaces (TUIs) for enhancing co-located design collaboration. Both technologies enable designers to collaborate by interacting with 3D models as the design representations. The paper analyzes the effe...

 With the increasing realisation of the importance of information and elicitation of knowledge, the need for improved methods of extraction and abstraction of information and knowledge has gained equal attention. To this end, visualisation methods have been viewed an effective way of abstracting information. Over the past three decades, these methods have undergone a rapid revolutionary progress, supported by sophisticated visualisation tools, analytical and simulation methodologies and tec...

 This paper presents a novel heating, ventilation, and air conditioning (HVAC) control architecture for office buildings, which uses the predicted mean vote (PMV) index of each occupant as feedback and offers them the opportunity to act on their own comfort level by signalling a possible thermal uncomfortable sensation to a personal user interface. A co-simulation EnergyPlus/Simulink has been used to test this new personalized and adaptive thermal comfort control in an office building for d...
