Despite a general belief among multimedia designers, there is little evidence that animation improves users' cognitive processing. One reason why animation has not met designers' expectations is that animations are usually complex and difficult to process. In this research we used a simple animation device to guide users in their processing of complex diagrams. The device, called sequential dis...

Mobile devices have fundamentally changed personal computing, with many people forgoing the desktop and even laptop computer altogether in favor of a smaller, lighter, and cheaper device with a touch screen. Doctors and patients are beginning to expect medical images to be available on these devices for consultative viewing, if not actual diagnosis. However, this raises serious concerns with re...

Much research in the large public display and mobile device area is focused on the synchronous use of the two platforms. Furthermore, there is an emphasis on interaction with content explicitly authored or generated for the large display context. By way of contrast, we present a prototype that displays information previously captured from mobiles of users unconcerned with how their content woul...

Force-feedback devices can provide haptic feedback during interaction with physical models for sound synthesis. However, low-end devices may not always provide high-fidelity display of the acoustic characteristics of the model. This article describes an enhanced handle for the Phantom Omni containing a vibration actuator intended to display the highfrequency portion of the synthesized forces. M...

In haptic simulation, a force feedback device is combined with a digital representation of a virtual world to create a kinesthetically immersive experience. The force feedback device, or haptic display, is usually a robotic manipulator with which a human operator interacts physically, usually through a handle, stylus, finger-pad or some other form of customized interface. Modeling of the haptic...

Problem statement: Content adaptation have been playing an important role in mobile devices, wherein the content display differs from desktop computers in many aspects, such as display screens, processing power, network connection bandwidth. In order to display web contents appropriately on mobile devices and on other types of devices such as hand computers, PDAs, Smart phones, it is important ...

This paper presents a longitudinal user study that investigated the adoption of some Bluetooth based functionalities for a public digital display in a high school. More specifically, the utilization of Bluetooth device naming extended beyond social identity representation and introduced the use of a simple interaction mechanism. The interaction mechanism involves recognizing parts of the Blueto...

This paper describes an accurate method to obtain the Tone Reproduction Curve (TRC) of display devices without using a measurement device. It is an improvement of an existing technique based on human observation, solving its problem of numerical instability and resulting in functions in log–log scale which correspond better to the nature of display devices. We demonstrate the effiency of our te...

In this demo, we present a system that can realize a spatial interaction between a handheld device and external displays via imperceptible on-screen markers. Our system can compute a full pose of the camera installed on the handheld device by extracting a marker from the external display, while a user does not notice where the marker is. This technology enables users to see Augmented Reality (A...
