Recently there are various innovative user interfaces such as a wireless motion controller Wiimote appeared to give a new user experience which is different from the traditional devices like a joystick, mouse, or keyboard. With the advent of technologies, display devices become larger and larger in screen size and offer high-resolutions, and tiled display systems are also used in various applications. Although there are some efforts on investigating new interfaces developed for the large screen, there are a few studies conducted on user interaction on large displays such as tiled display. In this paper, we present a study evaluating and analyzing the effects of mouse or Wiimote user interactions on four different kinds of displays with various sizes and resolutions.

This paper proposes a remote partitioned rendering method for displaying 3D applications on large tiled displays, which were developed using the Unity game engine. With the proposed method, one can represent them without additional development or any modifications to the applications. The paper verifies its feasibility by applying to a sample Unity-based application.

360-degree video streaming technologies have been widely developed to provide immersive virtual reality (VR) experiences. However, high computational power and bandwidth are required to transmit and render high-quality 360-degree video through a head-mounted display (HMD). One way to overcome this problem is by transmitting high-quality viewport areas. This paper therefore proposes a motion-constrained tile set (MCTS)-based tile extractor for versatile video coding (VVC). The proposed extractor extracts high-quality viewport tiles, which are simulcasted with low-quality whole video to respond to unexpected movements by the user. The experimental results demonstrate a savings of 24.81% in the bjøntegaard delta rate (BD-rate) saving for the luma peak signal-to-noise ratio (PSNR) compared to the rate obtained using a VVC anchor without tiled streaming.

Enhanced analysis is performed to design a wedge projection system with a slab structure that increases the projected image size. The specification values of the system such as the length of the slab structure and the imaging region are calculated and investigated using an optical simulation tool. We also propose a split imaging region method to represent a large tiled scene using the thin wedge waveguide structure. Experiments are performed to verify the feasibility of the proposed method.

We have developed nucleation control methods applicable to a zone-melting recrystallization excimer laser annealing process for poly-Si films. Ribbon-shaped Si grains of 2 ${\mu}m$-width were successfully aligned side by side by means of a comb-shaped beam, and we have successfully fabricated TFTs with channels formed in those grains. Electron mobility in the TFTs is as high as 677-$cm^2$/Vs.

볼륨 렌더링은 스칼라 데이터로 구성된 3 차원 볼륨 데이터를 가시화하는 기법을 가리키며, 유체 역학, 지진, 기상, 해안, 천문, 의료 등 다양한 분야에서 데이터를 분석하는데 널리 사용된다. 최근에는 대용량 볼륨 데이터가 생성되면서 고해상도 디스플레이에 대한 요구가 높아졌으며, 이에 따라 타일형 디스플레이 장치에서 볼륨 데이터를 가시화하려는 시도가 많이 이뤄지고 있다. 본 논문에서는 타일형 디스플레이 장치에서 볼륨 데이터를 가시화하는 기법을 구현했다. 볼륨 데이터 렌더링은 타일형 디스플레이 장치와 연결된 PC-클러스터에서 그래픽스 하드웨어를 사용하는 볼륨 렌더링 기법으로 수행했으며, 이렇게 렌더링된 결과 이미지를 컴포지팅함으로써 해당 디스플레이 장치에 적절한 이미지를 생성했다.
