Juiciness is visual pizzazz used to improve player experience and engagement in games. Most research has focused on juicy particle effects. However, text effects are also commonly used in games, albeit not always juiced up. One type is onomatopoeia, a ...

Software developers increasingly rely on automated methods to assess the correctness of their code. One such method is property-based testing (PBT), wherein a test harness generates hundreds or thousands of inputs and checks the outputs of the program ...

Virtual reality and immersive environments have gained significant attention for their potential for learning support. However, immersive concept maps have not yet been much investigated in the scientific literature. Starting from interactive concept ...

In this paper, we compare eyes-free input gestures to gestures produced in the presence or the absence of a visual feedback for a single-handed mobile device interaction. We consider two gesture sets ((i) freeform gestures (operands, rationally ...

As mobile user interfaces (UI) become feature-rich, navigation gets more complex. Finding features quickly starts demanding information-intensive strategies for decision-making—which can be challenging for older adults. Older adults examine fewer ...

Silent speech is unaffected by ambient noise, increases accessibility, and enhances privacy and security. Yet current silent speech recognizers operate in a phrase-in/phrase-out manner, thus are slow, error prone, and impractical for mobile devices. We ...

People are increasingly using their smartphones to 3D scan objects and landmarks. On one hand, users have intrinsic motivations to scan well, i.e. keeping the object in-frame while walking around it to achieve coverage. On the other, users can lose ...

The use of Head-Mounted Displays (HMDs) in Virtual Reality (VR) can cause gait disturbance problems for users because they are unable to see the real world while in VR. This is particularly challenging for individuals with mobility impairments who rely ...

Current technological progress has provided innovative methods and tools for learning and discovering various aspects of manual professions. To valorize their artifacts and mostly the craft and know-how behind them, museums are more and more attracted by ...

Exercise benefits people not only in physical health but also in mental health. Compared to individual workouts, many people prefer group exercise because of the additional peer support like guidance from experienced peers, and socializing benefits like ...

Many previous studies have cited the importance of trunk stabilization exercises in patients with stroke. However, the evidence for optimal trunk stabilization exercises for patients with stroke is still lacking.

To ...

While traditional interfaces in human-computer interaction mainly rely on vision and audio, haptics becomes more and more important. Haptics cannot only increase the user experience and make technology more immersive, it can also transmit information ...

The growing use of online videos across a wide range of applications, including education and training, demands new approaches to enhance their utility and the user experience, and to minimise or overcome their limitations. In addition, these new ...

Multimedia content and video-based learning are expected to take a central role in the post-pandemic world. Thus, providing new advanced interfaces and services that further exploit their potential becomes of paramount importance. A challenging area ...

Designing embodied playfulness has been explored as a method for problem-solving. However, when thinking about deploying such an approach in public space activities, we often face many limitations regarding safety and ambiance, especially for bodily ...

Precise and reliable directional feedback is crucial for electronic traveling aids that guide visually impaired people along safe paths. A large proportion of visually impaired people can determine light position using their light perception. This work ...

Smartphone touch screens are potentially attractive for interaction in virtual reality (VR). However, the user cannot see the phone or their hands in a fully immersive VR setting, impeding their ability for precise touch input. We propose mounting a ...

We present SmartAidView jacket to reduce the underestimation effect in human perception of assistive force. Pneumatic gel muscles (PGMs) were used as the wearable type actuators to assist wrist extension for this work. The SmartAidView jacket was made ...

We describe a novel technique to provide semi-private feedback on a shared public screen. The technique uses a no-onset presentation that takes advantage of perceptual limitations in human vision to avoid alerting other users to feedback directed at one ...

When learning sign language, feedback on accuracy is critical to vocabulary acquisition. When designing technologies to provide such visual feedback, we need to research effective ways to identify errors and present meaningful and effective feedback to ...
