The FIC(Flat Integrated Circuits)is widely used for good productivity but very difficult for visual identification. The required position tolerance is 0.05mm and orientation tolerance is 0.25 degree for assembly. The research was performed to detect FIC defects and to estimate the placement of FIC within the tolerances. In this study an automatic visual system is developed, which can successfully perform a fine assembly operation using the cartesian robot.

In this paper, a novel type of a visual servoing method is proposed for eye-in-hand robots by employing a self-organizing fuzzy controller. For this is there defined a new Jacobian riot to be the function of a relative position of the object but to be a function of the only image features. Instead of obtaining an analytic form of the proposed Jacobian, a self-organizing fuzzy controller is then proposed to alleviate difficulties in real-time implementation. To show the validities, the proposed method is applied to a 2-dimensional visual servoing task.

Studies on visual fatigues were activated after VDTs were rapidly introduced into the office works in 1980s. Various measurement methods and its measures were developed from those studies. Early studies frequently used simple measures such as near point of accommodation, near point of vergence, and CFF. Current researches focus on dark focus, dark vergence, and VEP which have a good relevance to the visual fatigues. In spite of the merit they also have some limits and disagreements. This survey summarizes the measures, measurement methods and relevant researches. Finally several topics are proposed for the future researches in Korea.

In this paper, a new algorithm is proposed to obtain important corner and real corner points of the simple objects and the visual robot graphics simulation using the results is studied. This is capable of performing as a debugging tool for task programming of a visual robot. And the robot motion is also simulated on a CRT terminal.

We propose an attention based object recognition system, to recognize object fast and robustly. For this we calculate visual stimulus degrees and make saliency maps. Through this map we find a strongly attentive part of image by stimulus degrees, where local features are extracted to recognize objects.

The effects of different optical characteristics between desktop CRT and TFT-LCD were compared in terms of visual performance during a 4-hr visual text and icon search tasks. The result showed that CRT is more suitable for presenting graphic information whereas TFT-LCD is suitable for presenting text information at the state of the art display technology.

In this paper, we propose a method to automatically extract stable visual landmarks from observed data for a mobile robot with stereo vision system. The robot selects as stable landmarks vertical line segments which are distinct and on planar surfaces, because they are expected to be observed reliably from various view-points. When the robot moves, it uses several, less uncertain landmarks for estimating its motion. Experimental results in real scenes show the validity of the proposed method.

Working with dynamic visual representations can help students-with-computer discover new mathematical ideas. Students translate among multiple representations as a strategy to investigate non-routine problems to explore possible solutions in mathematics classrooms. In this paper, we use the area models as new representations for our secondary students to investigate three problems related to the average speed of a particle. Students show their ideas in the process of investigating arithmetic mean, harmonic mean, and average speed through their created dynamic figures. These figures really utilize dynamic geometry software.
