PopCAD: Toward Paper-Based Fabrication Tools for Education
نویسندگان
چکیده
This paper describes a working prototype device, PopCAD, for straightforward, tangible 3-dimensional input and design. PopCAD is a paper-based pop-up computational artifact that can be carried about easily and unfolded into its "working" instrumental form. When unfolded, PopCAD allows the user to switch on LED lights in a 3D spatial array; the positions of these lights are sent to a desktop computer for display and manipulation in real time. The intent of the device is thus twofold: first, to provide an experience of embodied construction for students and 3D designers, and second, to illustrate the power and potential of designing working sophisticated instruments based on an inexpensive, flexible paper substrate. We describe PopCAD's architecture, its origins in earlier projects, and the learning potential inherent in such a device. We also show a variety of project ideas that the device can implement and we discuss what the device implies for the future of paper-based tangible instrumentation.

Simulation of Fabrication toward High Quality Thin Films for Robotic Applications by Ionized Cluster Beam Deposition
The most commonly used method for the production of thin films is based on deposition of atoms or molecules onto a solid surface. One of the suitable method is to produce high quality metallic, semiconductor and organic thin film is Ionized cluster beam deposition (ICBD), which are used in electronic, robotic, optical, optoelectronic devices. Many important factors such as cluster size, cluster...
متن کاملEffect of Education on the Awareness of Primigravida Couples toward Infant Care
Background: Infancy is one of the most critical stages of life, which requires parents to have adequate knowledge in order to provide careful nursing, attention and care for newborns. Given the importance of infant health, it is essential to teach proper child care techniques and principles to primigravida parents. This study aimed to evaluate the effect of education on the awareness of primigr...
متن کاملFab Lab: an Alternate Model of Ict for Development
There is a growing sense that the Digital Divide and the role of Information and Communications Technology (ICT) in international development need to be fundamentally reconceptualized. This paper presents the composition and the rationale behind the creation of a network of fabrication laboratories, FAB LABs, whose mission is to provide concrete examples that would lay the foundation for a new ...

By introducing new digital fabrication techniques and robotic fabrication in the 20th century, architects were encouraged to use innovative materials and novel tools to solve problems not only in design, but also in construction. Robots allow architects to design a more complex machining process for on-site fabricating work, but they were very costly and complicated as well. Because of rapid d...
متن کاملTranslation Technology Tools and Professional Translators’ Attitudes toward Them
Today technology is an integral part of professional translation; and it is generally assumed that translators’ attitudes toward translation technology tools influence their interaction with technology (Bundgaard, 2017). Therefore, the present two-phase study seeks to shed some light on what translation technology tools are and how professional translators feel toward them. The research method ...
