Output devices to view Virtual Reality (VR), like Head Mount Displays, are getting common lately. However, there is no standard input devices to tell computers user's intention in VR yet. According to the naive intuition, using real objects that has similar shapes as in VR is the better way than using controllers like mouses or game controllers to manipulate objects showed in VR. But is it true? To make it clear, we develop an game system like tower defense. Users played the game in two ways, one is using real objects, the other is using mouse to place "Towers". As the result of questionnaire after game plays, "easy to use" factor was lower for the real objects operation mainly because of the technical difficulties like object detection failure. But the "fun to use" factor was still higher for the real objects than the controllers. It show that using real objects has high potential for interaction between users and the VR system.

Visual analytics plays a key role in bringing insights to audiences who are interested and dedicated in data exploration. In the area of relational data, many advanced visualization tools and frameworks are proposed in order to dealing with such data features. However, the majority of those have not greatly considered the whole process from data-model mining to query utilizing on dimensions and data values, which might cause interruption to exploration activities. This paper presents a new interactive exploration framework for relational data analysis through automatic interconnection of data models, data dimensions and data values. The basic idea is to construct a relative and switchable chain of those context representations by integrating our previous techniques on node-link, parallel coordinate and scatterplot graphics. This approach enables users to flexibly make relative queries on desired contexts at any stage of exploration for deep data understanding. The result from a typical case study for the framework demonstration indicates that our approach is able to handle the addressed challenge.

There are a mass of design decisions within the design process, including the reasoning of design and the evolution of the conception, or undiscovered relevance between sketches/diagrams. If we don't realize the process of design by analysis of results further, the designer will not learn from experience and will not avoid the same mistake. This study through diagram following the linkography method, the critical decision CM (critical moves) will be revealed. By calculating the design process unit CM proportion of the number, the most important moves form a particularly large number of links. The CM can show the main idea of direction of subject, therefore, via CM, designers can understand what's the weakness of themselves and extending their knowledge, getting rid of the traditional thinking mod.

Designers tend to have repetitive design strategy in the process without notices. The elements setting the interactive function is to conform the user requirement and it can improve the user experiences. Although it has many information recorded on the paper, but via the think-aloud we can find out many implicit information. Then, we can go through the sketch to understand how we define the visualize graphic nodes and find out their implicit mode. By surfacing such behaviors, designers can focus on effective design strategies rather than repetitive design.

Feedback plays an important role in assisting users to better understand their energy consumption behaviour. This is particularly true when users want to change their behaviour in order to reduce their energy consumption, and to manage their usage more effectively so as to avoid putting unnecessary load on energy providers. This paper presents the time-tone visualization, which aims to assist users by displaying variations in energy consumption by different categories of household devices over time, and their respective contributions to the total energy usage load. A user study conducted to compare time-tone against area-charts shows that although the two visualizations are comparable, time-tone is more effective for cases where there are large variations in energy usage loads.

Graphic game engines have introduced even more advanced technologies to improve the rendering, image quality, ergonomics, and user experience of their creations by providing user-friendly yet powerful tools to design and develop new games. There are thousands of genes in the human genome that contain information about specific individual patients and the biological mechanisms of their diseases. The complexity in biomedical and genomic data usually requires effective visual information processing and analytics. Unfortunately, available visualisation techniques for this domain are limited, many in static forms. The open study questions here are as follow: Are there lessons to be learnt from these video games? Or could the game technology help us explore new graphic ideas accessible to non-specialists? This paper presents a visual analytics model that enables the analysis of large and complex genomic data using Unity3D game technology. This includes an interactive visualisation, providing an overview of the patient cohort with a detailed view of the individual genes. We illustrate the effectiveness of our approach in guiding the effective treatment decision in the cohort through datasets from the childhood cancer B-Cell acute lymphoblastic leukaemia.

This paper enlightens the ultimate requirement of piecewise cubic functions in graphic designing with having good control on the interpolatory curves and also having flexible tangents. To meet these requirements of graphic designing, a piecewise cubic trigonometric spline function is developed with three shape parameters. These shape parameters provide the flexibility in tangent on each sub interval of the data. The geometric characteristics of developed function are also deliberated here. The error of developed function is also calculated which is of order three.

Spatio-temporal dependent data, such as weather observation data, is data in which attribute values depend on both the time and space in which they are recorded. Typical visualization methods of such data that are employed in mass communication involve plotting the attribute values at each point in time on a map, and either displaying a series of such maps in time order using animation or displaying them by juxtaposing horizontally or vertically. Such methods are widely known, even by non-experts in analysis, but they have some problems. These methods force readers who want to grasp spatial changes in the attribute values to memorize the representations on the maps. The longer the time-period of data, the higher the cognitive load. In order to address such problems, we develop a novel visualization technique, named "Amatsubu," which statically represents multiple instantaneous values on a single map by overlaying them. We confirm the usefulness of this method through user studies, and also determine a weak point. The weakness is a lack of readability of information for each point in time, which can induce misreadings of spatial changes. We attempt to overcome this issue by introducing animation to Amatsubu, and transforming it into a semi-static representation technique. We confirm the effect of this improvement through another user study.
