The Thin‐film Micromirror Array (TMA) is a new reflective type spatial light modulator fabricated with the optical microelectromechanical system (MEMS) technology. A working projector prototype of 5,400 true ANSI lumen was presented at the Asian Display 1998 with three VGA format TMA modules and a 1 kW Xenon lamp. The prototype showed the optical efficiency of 22%, which was the highest optical efficiency among all the reflective and transmissive light modulators in the world. For the commercial projectors, XGA f
mat TMA is under development. The size of a micromirror of VGA format TMA is 97 μm by 97 μm while the size of eaxh micromirror of XGA format TMA is 50 μm by 50 μm. Efforts have been made to maintain the optical efficiency of the XGA TMA projector same as that of the VGA TMA projector. TMA projector prototype is brighter than any competing technology projectors in the world at the same lamp power, at least three times or more. The simplicity of the underlying principle and the highest optical efficiency of TMA enables high‐brightness and cost competitive projection displays which has been a dream in the past.
A space serves as a platform of experience, and the overall satisfaction of a space is shaped by various experiential elements that users encounter during their stay. This project aims to pinpoint the spatial experiences in the process of building a student-centered creative, collaborative, and communicative space in a university library that increase the utilization and satisfaction of the space. Furthermore, the project explores how these elements contribute to the overall 'placeness' of the space and how they can be integrated into the refurbishment process. Utilizing service design thinking as a guiding framework, we formulated a vision for the spatial experience, identifying key experiential elements across the servicescape's three dimensions. Specifically, we highlighted the allowance of permissible white noise for the 'ambient condition' dimension, movable furniture and ubiquitous floor outlets for the 'spatial layout and functionality' dimension, and a cozy rest area with a daily-changing arrangement emblematic of the dynamic, open, and independent nature of university students for the 'signs, symbols, and artifacts' dimension. We then generated diverse ideas for embedding the components in the space. The generated ideas were assessed through the desktop-walkthrough technique and incorporated into the renovation. After two months of use of the space, we evaluated students’ UX satisfaction through on-site observation and interviews, and verified that experiential components successfully stimulated students' activities, and the intended placeness was established within the space.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
