Evaluation of keyboard switches based on Kansei (human sensitivity) information

Abstract

A comfortable man-machine interfaces are required for current advanced systems. This paper aims at investigating the relation between reaction force of keyboard switches and human switch operation feeling.We investigate how each reaction force of switches effects to the touch feeling of keyboard switches via sensory test.The results of factor analysis for the questionnaire data obtained in the sensory test show that the most substantial factor is the feeling expressed by the words NClearn, "Smooth", "Stiff, and '(Clicking". Finally, each feeling described by each word is directly evaluated by reaction force or vice versa on dual scales. The dual scale for reaction forces and degree of feeling can be directly used for designing comfortable keyboard switch.

Beat gesture recognition and finger motion control of a piano playing robot for affective interaction of the elderly

“…The existing robotic piano players are deprived of the human player's touch and tend to produce music that sounds mechanical. To enhance the robot's skill of playing a piano, one of the task is to design an appropriate trajectory for the robotic fingers to follow while playing [21]. The other is to find a way to track this trajectory accurately.…”

A Study on Affection and Design Elements Affecting the User Satisfaction of Physical Keyboard

“…Sun and Fahn(2007)는 키보드 스위치의 물리적 특성이 인간과 생리학 적, 감성공학적으로 관련이 있다고 언급하였다. Watanabe and Kosaka(1995)에 따르면 시스템은 접촉 할 때 느껴지는 감성의 품질에 따라 그 등급이 매겨지고 작동하는 소리를 통해 평가 된다고 제시하였다. 하지만 물리적 키보드 사용 시에 느껴지 는 촉각 피드백이 인간의 오감 중의 하나임에도 불구하고 감 성과의 관계를 다룬 연구는 활발하게 이루어지지 않았다.…”
