This paper presents the results of an experiment measuring the difference of reading speed and preference when reading on paper or screen. Extending previous experiments on the topic of reading speed measurements, which usually concentrate in specific age groups, in this experiment, forty two participants from across the adult life span took part in reading on computer screen or on paper. Resul...

Computer display system users must integrate data across successive displays. This problem of across-display processing is analogous to the question of how the visual system combines data across successive glances (fixations). Research from cognitive psychology on the latter question is used in order to formulate guidelines for the display designer. The result is a new principle of person-compu...

This study examined how customers’ preference and purchase intention change depending on presentation type of information. Products’ information was manipulated on scale and order dimension. Participants made a decision on three situations choosing music(mp3) download plan, cell phone data plan, drinks voucher plan for a coffee shop as well. All stimuli were appeared through the computer monito...

A growing body of research shows several advantages to multimodal interfaces including increased expressiveness, flexibility, and user freedom. This paper investigates the design of such an interface that integrates speech and hand gestures. The interface has the additional property of operating relative to the user and can be used while the user is in motion or standing at a distance from the ...

We developed an interface system called “Marching Bear,” where the robot controller’s motions were reflected in the motions of certain characters appearing on a computer display. We then conducted a simple experiment to investigate the effectiveness of this interface system to see whether users felt that this interface system was enjoyable. We used a questionnaire and conducted an observation t...

This paper describes a method for enhancing the privacy of computer displays in public and semipublic areas. By operating the display at a higher-than-usual frame rate and alternately displaying frames of an arbitrary private image and a computed mask image, unauthorized viewers perceive one image, while authorized viewers with appropriately keyed shutterglasses see an entirely different (and p...

What is a computable set? One may call a bounded subset of the plane computable if it can be drawn at any resolution on a computer screen. Using the constructive approach to computability one naturally considers totally bounded subsets of the plane. We connect this notion with notions introduced in other frameworks. A subset of a totally bounded set is again totally bounded iff it is located. L...

The study examined the generalizability of the learning advantages produced by instructions that induce an external relative to an internal focus of attention (e.g., Wulf, G., H oû, M., & Prinz, W. (1998). Instructions for motor learning: Di€erential e€ects of internal versus external focus of attention. Journal of Motor Behavior, 30, 169±179.) to the feedback provided to the learner. Four gro...

This paper presents structural estimates of bidding behavior in eBay computer monitor auctions. We use our estimates to reject the use of Jump Bidding (Avery 1998) or “Snipe or War” bidding (Roth and Ockenfels, 2000). We also find that longer auctions only have a small effect on price and experienced auctioneers respond to this incentive. JEL Classification Numbers: C1, C7, D44, L1.

What: Project LISTEN is developing a novel weapon against illiteracy: an automated reading coach that displays a story on a computer screen, listens to a child read it aloud, and helps where 1. needed. The coach provides a combination of reading and listening, in which the child reads wherever possible, and the coach helps wherever necessary. We demonstrated a prototype of this coach at the ARP...
