With the increase of graph size, it becomes difficult or even impossible to visualize graph structures clearly within the limited screen space. Consequently, it is crucial to design effective visual representations for large graphs. In this paper, we ...

Online advisory chatbots are becoming increasingly popular and are often used to support user decision-making in different sectors. The design of such systems has been the object of investigation since it can alter the user’s perception and cognition. ...

Unfamiliar measurements usually hinder readers from grasping the scale of the numerical data, understanding the content, and feeling engaged with the context. To enhance data comprehension and communication, we leverage analogies to bridge the gap ...

Music streaming services are increasingly popular among younger generations who seek social experiences through personal expression and sharing of subjective feelings in comments. However, such emotional aspects are often ignored by current ...

Automatic stress tracking has become increasingly available on wearable devices. Research has investigated its use for individual stress management, largely within the traditional data-as-care framing. However, its use for stress sharing in social ...

Previous user experience research emphasizes meaning in interaction design beyond conventional interactive gestures. However, existing exemplars that successfully reify abstract meanings through interactions are usually case-specific, and it is currently ...

Visual metaphors, which are widely used in graphic design, can deliver messages in creative ways by fusing different objects. The keys to creating visual metaphors are diverse exploration and creative combinations, which is challenging with conventional ...

Within every interaction between a human and a computer, there exist the twin challenges of understanding the computer's current state and figuring out how to update it. Previous research has been aware of "the gulf of evaluation" and "the gulf of ...

Food-posting, a pervasive practice on social media platforms, opens a window for introspection on personal food intake, physical health, and mental well-being. Existing self-reflection tools on food intake usually require manual logging of dietary ...

The modulation of voice properties, such as pitch, volume, and speed, is crucial for delivering a successful public speech. However, it is challenging to master different voice modulation skills. Though many guidelines are available, they are often not ...

Despite the popularity of photo editors used to improve image attractiveness and expressiveness on social media, many users have trouble making sense of color filter effects and locating a preferred filter among a set of designer-crafted candidates. The ...

Emerging Augmented Reality (AR) technologies can enable situated interactive visual analytics beyond the screen. However, the presentation and interaction design of data visualization integrated into the physical environment may vary in different ...

The rapid development of biosensors and wearable devices has led to an increasing number of quantified self applications with physiological data. However, conventional graph-style visual representations which have been commonly used for behavior ...

Emerging online video-sharing websites such as YouTube allow users to access a huge number of videos and generate feedback via reviews and/or live comments (a.k.a. danmu), making it possible to summarize videos based on media and user responses ...
