This paper investigates user performance and gaze-hand coordination errors in gaze-pinch interaction across different task complexities involving gaze and hand gestures. We designed gaze-based single target pointing tasks with varying levels of gaze ...

Objects are indispensable tools in our daily lives. Recent research has demonstrated their potential to act as conduits for digital interactions with microgestures, however, the primary focus was on situations where the hand firmly grasps an object. We ...

Designing interaction techniques for end-users often involves exploring vast design spaces while balancing many objectives. Bayesian optimization offers a principled human-in-the-loop method for selecting designs for evaluation to efficiently explore such ...

Always-on, upper-body input from sensors like accelerometers, infrared cameras, and electromyography hold promise to enable accessible gesture input for people with upper-body motor impairments. When these sensors are distributed across the person’s body,...

A lack of accessible controls remains a barrier to disabled users engaging in virtual reality experiences. This paper presents a modified cognitive walkthrough of 120 virtual reality applications to identify 2,284 pairs of operant and resultant ...

Today touchscreens are one of the most common input devices for everyday ubiquitous interaction. Yet, capacitive touchscreens are limited in expressiveness; thus, a large body of work has focused on extending the input capabilities of touchscreens. One ...

An Interactive Audio-visual English Learning Software is developed based on the theories of language input and output as well as constructivism, which is applied in English speaking and listening teaching. Validity of the software is explored through ...

English writing composition is a mandatory course in the Translation Studies at tertiary level in China. This paper presents reflective steps taken in a 32-hour English composition course to 75 second-year Translation Major students at a university in ...

We present BezelGlide, a novel suite of bezel interaction techniques, designed to minimize screen occlusion and ‘fat finger’ effects, when interacting with common graphs on smartwatches. To explore the design of BezelGlide, we conducted two user ...

Touchscreens translate touches of all kinds into 2D coordinates. This limits the input vocabulary and constrains effective interaction to touches by the fingertip. Previous tabletop research extended the input vocabulary with a myriad of promising ...

In many realistic applications, the collected inputs of DNN face a big challenge: perturbations. Although the perturbations are imperceptible, they may cause incorrect prediction results. This paper proposes prediction stability to quantitatively ...

Obtaining a signal useful for continuous pointing input is still an open problem for wearables. While magnetic field sensing is one promising approach, there are significant limitations. Our key contribution in this work is a simulation of a system that ...

Recent technological advances have made head-mounted displays (HMDs) smaller and untethered, fostering the vision of ubiquitous interaction in a digitally augmented physical world. Consequently, a major part of the interaction with such devices will ...

While mobile devices have become essential for social communication and have paved the way for work on the go, their interactive capabilities are still limited to simple touch input. A promising enhancement for touch interaction is knuckle input but ...

Deformable interfaces are emerging in HCI and prototypes show potential for non-rigid interactions. Previous reviews looked at deformation as a material property of shape-changing interfaces and concentrated on output. As such,deformable input was under-...

Tool use extends people's representations of the immediately actionable space around them. Physical tools thereby become integrated in people's body schemas. We introduce a measure for tool extension in HCI by using a visual-tactile interference ...

We propose a method for accurately and precisely measuring the intrinsic latency of input devices and document measurements for 36 keyboards, mice and gamepads connected via USB. Our research shows that devices differ not only in average latency, but ...

Sliders are one of the most fundamental components used in touchscreen user interfaces (UIs). When entering data using a slider, errors occur due e.g. to visual perception, resulting in inputs not matching what is intended by the user. However, it is ...

Uncertainty is common when working with data and becomes more important as processing big data gains attention. However, no standard tangible interface element exists for inputting uncertain data. In this article, we extend the input space of two ...
