By using the head-mounted display (HMD), we can have an immersive virtual reality experience. But the user cannot see any information from the real world. To solve the problem, video seethrough HMD can acquire images from real environment, and present into the HMD, then, we could build a mixed reality (MR) or augmented reality (AR) system. However, how to append and calibrate cameras on HMD for recovering real environment is still a research issue. HTC VIVE has a single camera in front of its device. [Steptoe et al. 2014] and OVRVISION Pro proposed to append dual cameras to capture left and right images. Due to the difference of viewpoint, images captured by cameras are different to what human eyes see (figure 2). Although we could recover true 3D information with a depth map, there are still some occlusion areas that we cannot recover by single camera. Therefore, multiple cameras with different positions could complement each other for reducing occlusion areas. In this work, four configurations are simulated with a synthesized scene.
通过使用头戴式显示器(HMD)，我们可以获得身临其境的虚拟现实体验。但是用户无法看到来自现实世界的任何信息。为了解决这个问题，视频可视头戴设备可以从真实环境中获取图像，并呈现到头戴设备中，然后我们可以构建一个混合现实(MR)或增强现实(AR)系统。然而，如何在头戴式显示器上附加和校准相机以恢复真实环境仍然是一个研究问题。HTC VIVE的设备前只有一个摄像头。[Steptoe et al. 2014]和OVRVISION Pro提出附加双摄像头来捕捉左右图像。由于视点的不同，相机捕捉到的图像与人眼看到的图像是不同的(图2)。虽然我们可以通过深度图恢复真实的3D信息，但仍然有一些遮挡区域是单相机无法恢复的。因此，不同位置的多个摄像机可以相互补充，以减少遮挡区域。在这项工作中，用一个合成场景模拟了四种配置。

Sketch as the most intuitive and powerful 2D design method has been used by artists for decades. However it is not fully integrated into current 3D animation pipeline as the difficulties of interpreting 2D line drawing into 3D. Several successful research for character posing from sketch has been presented in the past few years, such as the Line of Action [Guay et al. 2013] and Sketch Abstractions [Hahn et al. 2015]. However both of the methods require animators to manually give some initial setup to solve the corresponding problems. In this paper, we propose a new sketch based character posing system which is more flexible and efficient. It requires less input from the user than the system from [Hahn et al. 2015]. The character can be easily posed no matter the sketch represents a skeleton structure or shape contours.
素描作为最直观、最强大的2D设计方法已经被艺术家们使用了几十年。然而，由于将2D线条绘制解释为3D的困难，它并没有完全集成到当前的3D动画管道中。在过去几年中，已经提出了几项成功的人物素描研究，例如动作线[Guay等人，2013]和素描抽象[Hahn等人，2015]。然而，这两种方法都需要动画师手动给出一些初始设置来解决相应的问题。本文提出了一种新的基于草图的人物造型系统，该系统更加灵活高效。它比[Hahn et al. 2015]中的系统需要更少的用户输入。无论草图代表骨架结构还是形状轮廓，角色都可以很容易地摆出姿势。

Knee brace is a sports product or medical equipment that increases the stability in the dynamics of the knee. The proper design of a subject-specific knee brace should take her anatomical characteristics into account since they are influential to the knee dynamics. However, anatomical information is hidden under the skin, and obtaining such information is restricted to expensive equipments such as Magnetic Resonance Imaging (MRI) device or Computed Tomography (CT) scan device.

In recent years, expressions close to realities have become possible thanks to the technologically advanced computer graphics. Secular change and weathering are important factors to create realistic computer graphics images. Metal rust is an important secular change and there are much research work on rust [Kanazawa et al. 2015]. Although the rust forming processes vary according to coating rain-water and seawater, dissolved oxygen contents of them and flowing water effects, no rust forming methods which have examined the object geometry of models and chemical reaction processes exist as far as we know. Our proposed method calculates water flowing on 3D models to reproduce the process of corrosion which advances from the surface region coated with water. Our corrosion simulation model takes into account the quantity of coating water and the chemical reaction processes. As a result, we confirm that the images close to the rust formed in reality can be obtained.

We propose a framework for using human acting as input for the animation of non-humanoid creatures; captured motion is classified using machine learning techniques, and a combination of preexisting clips and motion retargeting are used to synthetize new motions. This should lead to a broader use of motion capture.

Furniture-device is the device having furniture appearance and physical input and output function. The Escaping Chair is a furniture-device having physical and dynamic interaction with a user to let them perceive the intent of their action and personify the furniture. The Escaping Chair interacts with the bystanders by trying to move away from nearby people. By doing this, the device tries to make the person fail to sit on it, and stimulates their perception about sitting. The idea of a furniture-shaped device was extended from one of my previous artworks, which used furniture as input mechanisms. I exhibited the chair and observed the interaction sit produced with exhibition visitors. It succeeded in making people wonder during the interaction, as I planned, and making them further chase the chair, which indicates a new capability of the device. There were some challenges regarding load tolerance, detection latency and failure, which I have proposed improvements for.

The Synesthesia Suit provides immersive embodied experience in Virtual Reality environment with vibro-tactile sensations on the entire body. Each vibro-tactile actuator provides not a simple vibration such as traditional game controller, but we designed the haptic sensation based on the haptic design method we have developed in the TECHTILE[Minamizawa et al. 2012] technology. In haptics research using multi-channel vibro-tactile feedback, Surround Haptics [Israr et al. 2012] proposed moving tactile strokes using multiple vibrators spaced on a gaming chair. And then they also proposed Po2[Israr et al. 2015], which shows illusion of tactile sensation for gesture based games by providing vibrations on the hand based on psycho-physical study.

For high skilled players, an easy game might become boring and for low skilled players, a difficult game might become frustrating. This research's goal is to offer players a personalized experience adapted according to their performance and levels of attention. We created a simple side-scrolling 2D platform game using Procedural Content Generation, Dynamic Difficulty Adjustment techniques and brain computer data obtained from players in real time using an Electroencephalography device. We conducted a series of experiments with different players and got results that confirm that our method is adjusting each level according to performance and attention.

Diffusion curves [Orzan et al. 2008] (DCs) has risen as an attractive vector primitive for representing complex colour gradients. Its flexible mathematical definition, taking curves with colour values as input, can be easily adopted by artists and designers because curves represent an intuitive approach to 2D drawing and design. However, the (Laplacian) diffusion process is computationally expensive and naive DCs (solving the large sparse PDE naively) are consequently unattractive as a practical vector graphics primitive. Lots of work has therefore been undertaken to identify a practical framework for defining and rendering DCs.

We propose a dynamic spatial augmented reality (SAR) system with effective machine learning techniques and edge-based object tracking. Real-time 3D pose estimation is the significant problem of projecting images on moving objects. However, camera-based feature detection is difficult, because most targets have a texture-less surface. Image projection and projected images also interfere with detection. Obtaining 3D shape information with stereo-paired cameras [Resch et al. 2016] is still a time-consuming process, and using a depth sensor with IR [Koizumi et al. 2015] is still unstable and have a fatal time-delay for the dynamic SAR. Therefore, we quickly and robustly estimate the 3D pose of the target objects by using effective machine learning with IR images. And by the combined use of high-speed edge-based object tracking, we realize a stable and low-delay SAR for moving objects.
