We first in the history of vection research, challenged to induce cutaneous vection by providing the participants body with wind. Participants wore an eye mask to block out all outside visual information, and white noise was presented through a pair of earphones to block out all outside auditory information. We also provided body sway by using a horse-riding machine. The constant wind was provi...

It is generally thought that mean luminance and low spatial frequency information in a visual image are sharply attenuated at the retina, due to processes of light adaptation and the spatial filtering effects of lateral inhibition. Our results from interocular luminance masking suggest, however, that cortical masking effects play a primary role in the attenuation of low frequency sensitivity. R...

We report a new technique for building a wide-angle, lightweight, thin-form-factor, cost-effective, easy-to-manufacture near-eye head-mounted display (HMD) for virtual reality applications. Our approach adopts an aperture mask containing an array of pinholes and a screen as a source of imagery. We demonstrate proof-of-concept HMD prototypes with a binocular field of view (FOV) of 70°×45°, or to...

We developed a document browser that traces a user’s gaze position to support information navigation. It detects the user’s eye movements to generate a trace. The trace is represented as a mask image on the document, and also becomes a document attribute that can be used to find the document. The trace makes it possible to know which areas of the document were accessed earlier; thus enabling th...

results the mean heart rate values were significantly less in the sevoflurane group (p value < 0.05) at 25 minutes after the surgery. the mean blood pressure in the isoflurane group was significantly higher compared with the sevoflurane group in 10, 20 and 30 minutes after the surgery (p values = 0.0131, 0.0373 and 0.0028, respectively). these differences were clinically unimportant because hea...

treacher collin’s syndrome (tcs) is a rare inherited condition characterized by bilateral and symmetric abnormalities of structures within the first and second bronchial arches. patients with tcs present a serious problem to anesthetists maintaining their airway as upper airway obstruction and difficult tracheal intubation due to severe facial deformity. because of retrognathia, airway manageme...
