Novel concept for full‐color electronic paper

— Despite a steep increase in commercial devices comprising paper-like displays, a much desired feature is still missing: bright full-color electronic paper. A new reflective-display technology has been developed to solve this issue. For the first time, the principles behind this in-plane electrophoretic technology will be presented, which enables the realization of full-color reflective displays with a higher brightness than presently available e-paper technologies, without compromising paper-like properties such as viewing angle and ultra-low power consumption. An additional major advantage (e.g., for future low-cost manufacturing) is that, besides direct-drive and active-matrix configurations, a passive-matrix option with analog gray levels has been successfully developed.

46.1: Invited Paper: Novel Design for Full‐Color Electronic Paper

Despite a steep increase in commercial devices comprising paper-like displays, a much desired feature is still missing: bright full-color electronic paper. We have developed a new reflective display technology to solve this issue. for the first time we will report about the principles behind our in-plane electrophoretic technology, which enables the realization of full-color reflective displays with a higher brightness than all present e-paper technologies, without compromising paper-like properties like viewing angle and ultra-low power consumption. An additional major advantage (e.g. for future low-cost manufacturing) is that, besides direct-drive and active-matrix configurations, a passive-matrix option has been developed successfully.

Moving Tangible Interaction Systems to the Next Level

Understanding tangible interactions foundational concepts can lead to systems with direct, integrated, and meaningful data control and representation.

An analysis of input-output relations in interaction with smart tangible objects

This article focuses on the conceptual relation between the users input and a systems output in interaction with smart tangible objects. Understanding this input-output relation (IO relation) is a prerequisite for the design of meaningful interaction. A meaningful IO relation allows the user to know what to do with a system to achieve a certain goal and to evaluate the outcome. The work discussed in this article followed a design research process in which four concepts were developed and prototyped. An evaluation was performed using these prototypes to investigate the effect of highly different IO relations on the users understanding of the interaction. The evaluation revealed two types of IO relations differing in functionality and the number of mappings between the user and system actions. These two types of relations are described by two IO models that provide an overview of these mappings. Furthermore, they illustrate the role of the user and the influence of the system in the process of understanding the interaction. The analysis of the two types of IO models illustrates the value of understanding IO relations for the design of smart tangible objects.
