A Microcomputer Interfacing Course for Computer Science Majors

This paper describes a microcomputer interfacing course for computer science students. Students build simple logic circuits to interface a microcomputer with real‐world devices, such as stepper motor and digital displays, and program the computer to monitor and control these devices. Programs are written in Pascal and assembly language. The emphasis is placed on applications rather than on theory. This course is especially designed for computer science students who are proficient in software programming but have little or no experience in electronics. The experiments described here have been developed on the Apple ft microcomputer, but they can be easily adapted to other microcomputers.

Flower solid modeling based on sketches

In this paper we propose a method to model flowers of solid shape. Based on （Ijiri et aL, 2005）＇s method, we separate individual flower modeling and inflorescence modeling procedures into structure and geometry modeling. We incorporate interactive editing gestures to allow the user to edit structure parameters freely onto structure diagram. Furthermore, we use free-hand sketching techniques to allow users to create and edit 3D geometrical elements freely and easily. The final step is to automatically merge all independent 3D geometrical elements into a single waterproof mesh. Our experiments show that this solid modeling approach is promising. Using our approach, novice users can create vivid flower models easily and freely. The generated flower model is waterproof. It can have applications in visualization, animation, gaming, and toys and decorations if printed out on 3D rapid prototyping devices.     

Using Interactive Videodisc in Training Contexts

Interactive videodisc (IVD) represents the fusion of video and microcomputer technology so as to exploit the strengths of each whilst minimising the weaknesses of each. Research related to IVD is reviewed here to establish learner effectiveness, user acceptance, training time savings, design considerations, cost considerations and the contribution of interactivity. Implications for teaching and learning are explored.

The Effectiveness of Mime‐Based Creative Drama Education for Exploring Gesture‐Based User Interfaces

User interfaces that utilise human gestures as input are becoming increasingly prevalent in diverse computing applications. However, few designers possess the deep insight, awareness and experience regarding the nature and usage of gestures in user interfaces to the extent that they are able to exploit the technological affordances and innovate over them. We argue that design students, who will be expected to envision and create such interactions in the future, are constrained as such by their habits that pertain to conventional user interfaces. Design students should gain an understanding of the nature of human gestures and how to use them to add value to UI designs. To this end, we formulated an ‘awareness course’ for design students based on concepts derived from mime art and creative drama. We developed the course iteratively through the involvement of three groups of students. The final version of the course was evaluated by incorporating the perspectives of design educators, an industry expert and the students. We present the details of the course, describe the development process, and discuss the insights revealed by the evaluations.     

WebCT and Its Growth as a Type II Application

Abstract

Maddux, Johnson, and Willis mentioned in 1992 some “yet-to-be-developed types” that “have the potential to be Type II software if they are used in such a way that the user is given the ability to learn in new and better ways.” The authors of this paper will frame the discussion of learning management systems (LMS) around the concept of Type I and Type II applications of computers in education. We suggest that with the new trends of interoperability within WebCT, more researchers will accept WebCT as a potential Type II application. As more interactive learning objects are developed and shared on the WebCT format, it should be easier for instructors to create and teach courses that reflect the value systems expressed in the concept of Type II learning.

Data Our Bodies Tell: Towards Critical Feminist Action in Fertility and Period Tracking Applications

ABSTRACT

This article situates reproductive applications as an emerging “do-it-yourself” health technology in need of feminist technical communication action. The authors focus on Glow, a fertility and period tracking application, and argue that though this application promises user’s self-empowerment over their reproductive health, individual agency is often reduced. The authors consider how technical communication scholars can intervene in fertility and period tracking applications through a redesign of how consent is obtained when collecting user’s personal health information.

VQT: value cardinality and query pattern based R-schema to XML schema translation with implicit referential integrity

In this paper, we propose a new relational schema （R-schema） to XML schema translation algorithm, VQT, which analyzes the value cardinality and user query patterns and extracts the implicit referential integrities by using the cardinality property of foreign key constraints between columns and the equi-join characteristic in user queries. The VQT algorithm can apply the extracted implied referential integrity relation information to the R-schema and create an XML schema as the final result. Therefore, the VQT algorithm prevents the R-schema from being incorrectly converted into the XML schema, and it richly and powerfully represents all the information in the R-schema by creating an XML schema as the translation result on behalf of the XML DTD.
