1G-32　Investigation of Operating Forces of the Automotive Tactile Switch regarding Various Positions

Abstract

The objective of this study is to investigate affective preference of the automotive tactile switch which influences package controllability and user satisfaction. In order to accomplish this objective, the independent variables for this experiment were package location (door trim, crash pad, steering wheel (L), steering wheel (R), center fascia, center console and overhead console) and operating force (1.5N, 2.0N, 2.5N, 3.0N and 5.0N). Furthermore, we constructed an automotive seating buck based on actual location data for switch assemblies that consisted of similar tactile switches. Then we measured affective preference on the operating force for each switch in each package location on a 7 point Likert scale. The ANOVA results for affective preference on the whole package location categorized the package locations into three groups for driver behavior: tapping zone, reaching zone and grasping zone. SNK posthoc-analysis revealed that the tapping zone showed that the operating force preferred by the users was 2.0N and 2.5N. The results for the reaching zone showed that users preferred the 3.0N operating force while the results for the grasping zone showed preference for the 3.0N and 5.0N operating forces. We expect the results of this study to be utilized to improve the affective quality of the automotive tactile switch.

Improving tactile feedback during push switch operation using intelligible operating sound

“…Displacement was set according to the specification of the switch used for switch A recording. The magnitude of the actuation force was selected based on the push switches used in general automotive products (Ban et al, 2013;Gaspar et al, 2017).…”

“…However, as per reports, more elderly people prefer switches with lower actuation force than younger people (Shibano et al, 2002); thus, from the perspective of universal design, excessive actuation force is undesirable. Additionally, a survey on the correspondence between the actuation force of in-vehicle switches and their mounting positions reported that the preferred switch actuation force differs depending on the mounting position of the switches (Ban et al, 2013). This indicates that for certain switches, increasing the actuation force could reduce its usability.…”

An Ergonomic Shape Design for Automotive Push-Return Switches

“…Stimulus received through sensory systems has a hierarchical structure that composes complex sensibility from a simple sensibility to make an overall feel of satisfaction or dissatisfaction (Choe, 2013). Therefore, in this study, overall satisfaction of operation at the top was set as dependent factor, and seven-point Likert scale was used for analysis.…”

“…Users preferred the operating force at around 2.5~3.0N, which also showed difference by the operation mode. In case of tapping zone where switch was comfortably pressed, an operating force of 2.5N was the most preferred, while in a reaching zone where switch was pressed by stretching hands and a grasping zone where hands were wrapped, an operating force at 3.0N was the most http://jesk.or.kr preferred (Ban et al, 2013).…”

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

“…하지만 물리적 키보드 사용 시에 느껴지 는 촉각 피드백이 인간의 오감 중의 하나임에도 불구하고 감 성과의 관계를 다룬 연구는 활발하게 이루어지지 않았다. 실제로 스위치와 관련하여 감성과의 관계를 다룬 연구로 Ban et al(2013)는 사용자의 만족도에 영향을 끼치는 자동차의 스위치의 촉각과 관련된 감성 선호도를 연구하였다. 이 때, 만 족도에 영향을 미치는 스위치의 촉각을 탐색하는 데 있어 콘솔 과 같은 패키지의 위치와 조작력을 의미하는 힘의 2가지를 독 립변수로 고려하였다.…”
