Interactive technologies require the user to frequently generate purposeful movements, where actions are guided towards targets. While delays between the movement onset and the corresponding update within the virtual space have been shown to impair target ...

Copy-and-paste operations are the most popular features on computing devices such as desktop computers, smartphones and tablets. However, the copy-and-paste operations are not sufficiently addressed on the Augmented Reality (AR) smartglasses designated ...

One-handed Back-of-Device (BoD) interaction proved to be desired and sometimes unavoidable with a mobile touchscreen device, for both preferred and non-preferred hands. Although users? two hands are asymmetric, the impact of this asymmetry on the ...

We conducted an empirical investigation of the visual information requirements for target detection and threat identification decisions in the dismounted soldier context. Forty soldiers viewed digital photographs of a person standing against a forested ...

In GUIs, there are clickable objects that have a difference between the motor and visual widths. For example, when looking at an item on a navigation bar, users think that the text length (the visual width) means the motor width. However, when a cursor ...

As the most common writing material in our daily life, paper is an important carrier of traditional painting, and it also has a more comfortable physical touch than electronic screens. In this study, we designed a shadow-art device for human-computer ...

Touch interaction is usually implemented on a computer screen or a projected surface. However, tactile quality of paper is attractive and intuitive for people to manipulate in traditional paintings and storytelling. In order to enable touch interaction ...

Eyes-free target acquisition is a basic and important human ability to interact with the surrounding physical world, relying on the sense of space and proprioception. In this research, we leverage this ability to improve interaction in virtual reality (...

Both situational handicaps and motor impairments can make small targets difficult to acquire accurately when using a mouse. The expansion cursor was designed to make accurate movements easier to perform. For every click of the mouse, users can choose ...

Touch latency has been shown to reduce users' performances but most studies focus on one-handed elementary tasks such as pointing or tracking a single object. The everyday use of touch devices is made, however, of more complex "composite" tasks ...

Audio, visual, and proprioceptive actions are involved when manipulating a graphic tablet musical interface. Previous works suggested a possible dominance of the visual over the auditory modality in this situation. The main goal of the present study is ...

Accurately predicting the accuracy of finger-touch target acquisition is crucial for designing touchscreen UI and for modeling complex and higher level touch interaction behaviors. Despite its importance, there has been little theoretical work on ...

Future flight deck designs from various avionics manufacturer incorporate touchscreen technology. There is little published research investigating the impact of inflight vibrations and increased G-Force (+Gz) on touchscreen usability. A Fitts' law ...

In this work we introduce 2D-Dragger, a unified touch-based target acquisition technique that enables easy access to small targets in dense regions or distant targets on screens of various sizes. The effective width of a target is constant with our tool,...

The purpose of pitch correction is to assist a musician in playing notes with accuracy and precision, without preventing expressive pitch variations. This study presents and examines a new method for automatic pitch correction: Dynamic Pitch Warping (DPW)...

We present two contributions toward improving the accessibility of touch screens for people with motor impairments. First, we provide an exploration of the touch behaviors of 10 people with motor impairments, e.g., we describe how touching with the back ...

During conversational practices, such as a tablet-mediated sales conversation between a salesperson and a customer, tablets are often used by two users who prefer specific bodily formations in order to easily face each other and the surface of the ...

The recent advances made in human-computer interaction have allowed us to manipulate digital contents exploiting recognition-based technologies. However, no work has been reported that evaluates how these interfaces influence the performance of ...

Edge targets, such as buttons or menus along the edge of a screen, are known to afford fast acquisition performance in desktop mousing environments. As the popularity of touch-based devices continues to grow, understanding the affordances of edge ...

The popularity of touchscreen mobile devices gives users a variety of useful apps and functionality on the move. As a result, mobile devices are being used in a range of different contexts. One common scenario that has received little attention from ...
