For the design of virtual desktop, more natural, intuitive, and actual interaction styles have become the main design principle. In this paper, we present a virtual 3D desktop which integrates physics and bimanual input commands based on pen + touch. Objects on the desktop own physical properties, such as mass, dimensions, gravity etc. And they can be dragged casually and collide other objects under...
In this paper we present a novel technique called Stripe Action for performing icons in multi-touch interfaces. The technique has two operational modes: local and global modes which are used for dealing with single or multiple icons. We focus on addressing three fundamental operations: selection, zooming and rotation. Stripe Action can set up links among icons and endow the same attribute to each...
In this paper, we present a novel gesture technique that couples both touch and pen inputs together for multi-touch and pen-enabled interfaces. This gesture design can fuse the advantages of both inputs from fingers and pens, which can alleviate the “fat finger” problem by introducing the accuracy input from pen-tips. The gesture design includes six types of hybrid gestures that carefully consider...
Human computer interaction technology has been applied too many in Financial terminal (with Automated Teller Machine as an example) design, such as interface design. In this paper, we have done a survey on human computer technology for financial terminals and present an investigation of the ATM design on the precious literatures. The user experience test and evaluation of the prototype are reviewed...
In this paper we presented two novel software-based techniques for generating extra input states in pen-based interfaces: Circular-gesture and Double-ellipse. Circular-gesture employs a circular stroke to produce a scalar value. When the value surpasses a specified threshold an extra input states is produced. Double-ellipse exploits double ellipses to simulate binary buttons of mice to generate input...
In his paper we introduce a novel interaction technique that improves target acquisition in pen-based interfaces. This technique is called Beam Cursor. The Beam Cursor exploits the sliding motion and dynamically updates the effective width of targets on screen according to the original location of the pen-tip, such that even if the pen-tip lands in the vicinity of a target the target can easily be...
This study empirically explores the properties of input modalities sensed from flipping a cube-based tool. By tracking the fiducial marker on each side of the cube in real-time, basic operations such as flipping can produce various input modalities. We present the results of an experiment that investigates the use of these input modalities to perform a set of experimental tasks. The task of the experiment...
Pen tilt is an additional input from digital pens, which indicates the posture information of holding a pen. In this study we couple tilt input with user interactions and explore its potential of improving user interactions. We first investigate human ability of users' controlling pen tilt in pen-based interactions. Based on the understanding of human ability of controlling this input modality we...
In this study we propose a novel bimanual selection technique called Lever Cursor for distant target acquisition in the interface of multitouch tabletop. Lever Cursor couples the absolute and relative manipulation modes together. The two manipulation modes are aimed at close and distant target selections respectively. A circle widget is also designed for flexibly switching the two modes. An experiment...
In this study we propose a novel bimanual interactive technique for scrolling tasks. In this technique two mice are employed to perform scrolling tasks at the same time. One wheel on one mouse is used to control rough scrolling performance and one wheel on the other mouse is used to control precise scrolling performance. A formal experiment with a series of standard scrolling tasks in a document was...
This study empirically explores a cube-shape tool based on computer vision, focusing on the properties of its input modalities and design space. By tracking the fiducial marker on each side of the cube in real-time, basic operations such as flipping, rotating and tilting can produce various input modalities. We present the results of an experiment that investigate the use of these input modalities...
Pressure and strokes are the much natural input modalities from pens. This study investigates the potentials of coupling pressure and strokes with pen-based interactions by discussing the possible strategies of using them. Pressure can be used as discrete or continuous manners, which are explored by two presented techniques: two-layer operation and Pressure Cursor. An experiment was conduct to determine...
Pie-menu, a very effective item-selection widget, has been proposed to enhance item-selection tasks in pen-based devices such as PDAs (personal digital assistants) and Tablet PCs. The significant advantage of Pie-menu is that it enables users to select items within a menu with only a short distance for the pen-tip to move. However, as the number of items to be selected increases, the architecture...
In this paper, the human interactive ability to use force control devices under sitting and standing postures was investigated. Subjects were asked to test a force input device which had 10 different target levels representing consecutive force ranges (0 to 4N) with visual feedback (number and bar graphs) in each of two postures. The experimental results indicate that no significant difference was...
