Various kinds of high presence displays are developed and used in recent years. However, it is difficult to quantitatively evaluate the "presence". In this study, we tried to define the word of presence operationally by measuring the biological information of the users. In the experiment, the conditions of 2D/3D images, viewing angles, and resolutions of the displayed images were changed. And the electrocardiogram, facial skin thermo gram, and eye movement of the users were measured when they were looking at the displayed images. From the result, it was shown that the RRV value decreases, the nose skin temperature did not decrease, and the frequency of eye movement increased, when the user were looking at the high presence image. This situation means the state where the user is concentrating his mind, feeling relax, and being interest in the displayed image. From the results, we proposed the index value of the word of presence by using the RRV value, the nose skin temperature, and the frequency of high presence sensation.
