A differential electromagnetic transducer (DET), which has similar frequency characteristics to those of the normal middle ear, has been designed and implemented for an implantable middle ear (IME). In order to optimize the DET characteristics that are practically determined by the electromagnetically forced vibration, a finite element analysis (FEA) simulation is carried out. The designed DET according to the simulation results is implemented using micro-machining technology. The vibrating displacement of the DET is about 200 nm in the range of 0.1 to 1.5 kHz when 1.5 mA/sub rms/ current is applied to the coil.

This paper summarizes progress to date on the WSU model for engineering mathematics education, an NSF funded curriculum reform initiative at Wright State University. The WSU model seeks to increase student retention, motivation and success in engineering through application-driven, just-in-time engineering math instruction. The WSU approach involves the development of a novel freshman-level engineering mathematics course EGR 101, as well as a large-scale restructuring of the engineering curriculum. By removing traditional math prerequisites and moving core engineering courses earlier in the program, the WSU model shifts the traditional emphasis on math prerequisite requirements to an emphasis on engineering motivation for math, with a just-in-time structuring of the new math sequence. This paper summarizes the development to date of the WSU model for engineering mathematics education, including a preliminary assessment of student performance and perception during the initial implementation of EGR 101. In addition, an assessment of first-year retention results is anticipated in time for the conference
This study examined the effects of synchrony and the number of cues on the person perception process in computer-mediated communication. One hundred and forty-two participants in groups of three or four engaged in col...

There are a wide variety of ways to present information at the front of a classroom. These include chalk on a blackboard, markers on a whiteboard, pens on transparencies, and computer projection systems. While computer-based presentation systems provide many opportunities both in and out of the classroom, there may also be many limitations. In-class spontaneity and dynamic exposition might be restricted. Class preparation time might increase dramatically when compared to the amount required to prepare handwritten materials. Certain presentation techniques may no longer be available. This paper will introduce a computer-based presentation system modeled on handwritten transparencies. It will then discuss how it addresses the above issues as well as how it can be used in and out of the classroom. These will be explored in the context of its use while teaching an undergraduate discrete mathematics course. Copyright 2004 ACM.

The fundamental question for an information-rich virtual environment is how to access and display abstract information. We investigated two existing navigation techniques: Hand-Centered Object Manipulation Extending Ray-casting (HOMER) and Go-Go navigation, and two text layout techniques: within-the-world display (WWD) and heads-up display (HUD). Four search tasks were performed to measure participants' performance in a densely packed environment. HUD enabled significantly better performance than WWD and the Go-Go technique enabled better performance than the HOMER technique for most of the tasks. We found that using HOMER navigation combined with the WWD technique was significantly worse than other combinations for difficult naïve search tasks. Users also preferred the combination of Go-Go and HUD for all tasks.

We investigate how users interact with the results page of a WWW search engine using eye-tracking. The goal is to gain insight into how users browse the presented abstracts and how they select links for further exploration. Such understanding is valuable for improved interface design, as well as for more accurate interpretations of implicit feedback (e.g. clickthrough) for machine learning. The following presents initial results, focusing on the amount of time spent viewing the presented abstracts, the total number of abstract viewed, as well as measures of how thoroughly searchers evaluate their results set.
