We present a case with walking-induced equinovarus caused by dystonic contraction of the left ankle. This abnormal motor behavior occurred only when the patient walked, more specifically when the left leg was at the end of the swing phase. Surface electromyography confirmed continuous abnormal discharges in the left gastrocnemius muscles during the swing(More)
Due to the wide spread use of smart phones and PCs, people can access information everywhere in everyday life. However, there are very few methods to access content within an bathing environment. Some people carry smart phones into a bathroom but it is unnatural to be holding a device during bathing. This paper proposes an interactive water surface display(More)
Information is becoming accessible everywhere in everyday life due of the spread of smart phones and portable personal computers; however are very few methods in accessing contents in a bathing environment. Sometimes smart phones can be carried into a bathroom but it is unnatural to be holding a device at during bathing, so a suitable technique for(More)
The AquaTop Display is system that uses the projection of images onto cloudy water. This system allows the users limbs to freely move through, under and over the projection surface. As the projection medium is fluid, we propose new interaction methods specific to this medium by using a Kinect Depth Sensor. Scooping up water, protruding fingers out from(More)
In the sustainable ITS project at the Center for Collaborative Research, the University of Tokyo, an experiment platform is developed for drivers' characteristics analysis on the moving-based driving simulator. In the upper-level microscopic car traffic flow simulator, a prototype driver model and vehicle dynamics model are developed with flexibility in the(More)
PURPOSE We analyzed the symmetry and pointedness of the posterior segment of highly myopic eyes. METHODS We studied 234 eyes of 117 patients with bilateral high myopia (refractive error ≤-8.00 diopters [D]) and 40 eyes of 20 patients with emmetropia (refractive error between -1.0 and +1.0 D). Volume renderings of high-resolution magnetic resonance (MR)(More)
We fabricated a single-electron device (SED) that has many nanodots. Oscillatory characteristics and multi-gate capabilities of SEDs were used to eliminate size fluctuation and achieve a high functionality. We fabricated a Si nanodot array device, which has two input gates and a control gate, and tested its basic operation characteristics experimentally.(More)
BACKGROUND In many countries, gastric cancer is not diagnosed until an advanced stage. An Internet-based e-learning system to improve the ability of endoscopists to diagnose gastric cancer at an early stage was developed and was evaluated for its effectiveness. METHODS The study was designed as a randomized controlled trial. After receiving a pre-test,(More)
In this paper, we show the outline of our research on interactive traffic environment, under which we are developing mixed reality traffic experiment space. In order to develop sophisticated ITS applications, it is very important to analyze human factor, but there is few method to obtain human factor, thus, we have decided to create interactive traffic(More)
