We studied visual clarity according to the difference of color temperature by using black and white printed paper and four sheets of colored paper under LEDs. We tested students in their twenties, under 3,000, 4,000, 5,700 and 6,500K LEDs (Ra=80). The results show visual clarity is proportioned to color temperature.

The Direct Arm(DDA) is a SCARA typed direct drive manipulator with three degree of freedom(DOF) using the direct motor of the NSK company. In the paper, we propose a convenient interface for the SCARA-type robot which is practical to use. The proposed Visual Robot Teaching Mode using 3D graphics replaces the current teaching box. And besides this graphical teaching software can be implemented on the PC which is company used as a robot controller. This program was developed for the Windows 95 OS.

Optical visual cryptography was proposed by conjunction of the optical theory with the cryptography. However, it had some difficulties. The problems occurred in the process of transferring data processing system from visual to optics. Therefore, it is appropriate to approach these problems in terms of optics. The results show that the optical visual cryptography system has both the effectiveness and reliability as well as real-time implementation property.

Optokinetic nystagmus(OKN) testing is an useful tool for assessment of human visual function. Specially, this method has been used for assessing visual function in infants and malingering patients. OKN drum and OKN tape are the common devices currently used for clinical cases. In this paper, we present newly the automated and computerized method for the quantitative and objective assessment of visual acuity in OKN testing.

In this paper, we designed a embedded system that will perform a primary role of Tangible Space implementation. This hardware includes function of image capture through camera interface, image process and sending off image information by LAN (local area network) or WLAN(wireless local area network). We define this hardware as a network based Visual Agent Platform for Tangible Space

Visual defect inspection for electronics parts manufacturing processes is comprised of 2 steps - automatic visual inspection by machine and inspection by human inspectors. It is necessary that spatial points which were detected by the machine should be adequately clustered for subsequent human inspection. This research deals with the spatial clustering algorithm for the purpose of process productivity improvement. Distribution based clustering is newly developed and experimentally confirmed to show better clustering efficiency than existing algorithm - area based clustering.

Human visual emotion were investigated by analyzing HRV from ECG signals, which were varied by the visual stimuli. In this paper, twelve university students experienced visual emotion by pictures from IAPS. ECG and subjective rating were obtained for human emotion evaluation. For determination of HRV, ECG was extracted into HF and LF via power spectrum analysis. The results showed that HRV is good for discrimination between positive and negative emotions.

In this paper, PD-like visual servoing is modified in two ways: a sliding-mode observer is applied to estimate the joint velocities, and a RBF neural network is used to compensate the unknown gravity and friction. Based on Lyapunov method and input--to-state stability theory, we prove that PD-like visual servoing with the sliding mode observer and the neuro compensator is robust stable when the gain of the PD controller is bigger than the upper bounds of the uncertainties. Several simulations are presented to support the theory results.
