In the artwork, the topic of life space has been discussed. Instead of physical space, mental space of human being was considered. People usually focus on themselves to solve various life tasks, and the scales of their mental space influence how they realize the world. The artwork tried to arouse people to aware the connection between mental space and life space. The Sand Scope introduces a microcosm of the world, for comparing the scale of mental space with the scale of the microcosm, from the relative scales between the microcosm and the whole world. From the new perspective, the Sand Scope reminds people to escape from the routine of their daily lives, for rethinking meaning of life. Multimedia input contains gray image analysis to form the stamps with portraits of current audiences and past participants, color image subtraction to compose texture of the mountain drawing with wearing cloth information on the painting, and a buffer with timer to capture and replay ambient sounds continuously in a delayed time, along with color images with blending effect in the period. In the interactive installation, an improvisational painting in the form of a Chinese brush painting with stamps from connoisseurs was exhibited. The generation of stamps from the audiences on the painting also indicates that they are parts of the microcosm. The microcosm was constructed from the elements of the inhabitants who live in the real world in physical aspect, and the awareness of meaning of life implies harmony between nature and humanity on the Zen painting in mental aspect.

In the artwork, the topic of One has been discussed. Broadly speaking, it implies the whole beings in the universe, and it also narrows down to individuals. Human being was considered and it can be described in physical layer and mental layer. The appearance of people as the protective coloration in the society, and that creates the self-identity of themselves and the impressions of the others. The artwork tried to arouse people to aware the influences of cognition from their minds by visualizing the cognition. The physical properties of human being contain face expression, body shape, wearing cloth and talking voice are transformed into five elements of Chinese Taoist philosophy: wood, fire, earth, metal and water. After the transformation, the interactive installation is performed as an improvisational colorful Chinese brush painting with mimic echoing sounds. Multimedia input contains gray image analysis to form the black block on the painting, color image subtraction to compose the color block on the painting, and a buffer to capture and replay sounds continuously. In the indoor exhibition, the camera was set to capture the audiences coming from the door. In the interactive installation, the dynamic improvisational painting with echoing sounds as evidence remind audiences the way they exist, and that arouse them to rethink the cognition of themselves from the many clones who used known to be "me". In a collaborative interaction, the clones from the crowd also arouse audiences to aware of their impressions on the others. An improvisational painting as colorful Chinese brush painting was exhibited, in which reveals countenance, contour, apparel and utterance in physical point, and the awareness of the cognition of selves and of the others in mental aspect.

In the artwork, the topic of flowing human figures has been discussed. People pass through familiar places day by day, in which they create connection among them and the city. The impressions, memories and experiences turn the definition of the space in the city into place, and it is meaningful and creates a virtual layer upon the physical world. The artwork tried to arouse people to aware the connection among them and the environment by revealing the invisible traces. The interactive installation was set in outdoor exhibition, and a camera was set align the road and a projector was used for performing image on the wall of the nearby building. Object detection technology has been used in the interactive installation for capturing movements of people. GMM modeling was adopted for capturing frames with vivid face features, and the parameters was set for generating afterimage effect. The projected picture on the wall combined with 25 frames in different update time setting for performing a delayed vision, and only one region in the center of the image played the current frame in real-time, for arousing audience to notice the connection between their movements and the projected picture. In addition, some of them were reversed in horizontal direction for creating a dynamic Chinese brush painting with aesthetic composition. The remaining figures on the wall as mark or print remind people their traces in the city, and that creates the connection among the city and people who has been to the place at the same time. In the interactive installation, the improvisational painting of body calligraphy was exhibited in a collaborative way, in which revealed the face features or human shapes of the crowd in physical point, and also the collaborative experiences or memories in mental aspect.

The purpose of this study is to develop a non-invasive sleep monitoring system to distinguish sleep disturbances based on multiple sensors. Unlike clinical sleep monitoring which records biological information such as EEG, EOG, and EMG, in this study, we aim to identify occurrences of events from a sleep environment. A device with an infrared depth sensor, a RGB camera, and a four-microphone array is used to detect three types of events: motion events, lighting events, and sound events. Given streams of depth signals and color images, we build two background models to detect movements and lighting effects, and audio signals are scored simultaneously. Moreover, we classify events by an epoch approach algorithm and provide a graphical sleep diagram for browsing corresponding video clips. Experimental results in sleep condition show the efficiency and reliability of our system, and it is convenient and cost-effective to be used in home context.
