This paper presents the results of an experiment comparing mouse, penand touch-inputs in computerized figural creativity test. The results show no statistically significant differences in creativity scores obtained by participants using mentioned devices as computer input methods. The results indicate that creativity testing can be introduced to a variety of modern computer devices with insigni...

The common use of mobile terminals is for text input. However, mobile terminals cannot be equipped with sufficient amount of keys because of the physical restrictions. To solve this problem we developed an input method using surface electromyogram (sEMG), treating arm muscle movements as input signals. This method involves no physical keys and can be used to input Japanese texts. In our experim...

Timbers of multiple tree species and sizes are often traded in a single market. Some previous studies have empirically examined their price interdependences, but the drivers such relationships remain unclear. I demonstrated with rational expectations model that when timbers two (or sizes) were gross substitutes production, steady-state ratio between prices was dependent on relative quality ease...

Chinese characters that are similar in their pronunciations or in their internal structures are useful for computer-assisted language learning and for psycholinguistic studies. Although it is possible for us to employ imagebased methods to identify visually similar characters, the resulting computational costs can be very high. We propose methods for identifying visually similar Chinese charact...
