| Abstract(in English) | In the case of the persons with severe physical disabilities, scanning method, which can be controlled with only one switch, is necessary to input letters to express his/her thoughts. Though the input speed of kana letters is improved by the addition of the row of letters used with higher probability with the consideration of preceding letter, users' mental workload increases, because he/she has to watch both additional row and the original letter table. As it is expected that users' mental workload decreases by using different background colors for letters included in additional row, we have indicated its effectiveness by using three indices, that is, input speed, mental workload and users ' preference. |
