This study aims to identify the characteristics of preferred gestures for using electronic devices by age. Gestures are affected by the personal mental concept, which varies with age. This is, gesture preference could be different depending on age. Few studies have been conducted to identify the similarities and differences of preferred gestures by age. In an experiment, a total of 32 participants were recruited with various age bands. The participants evaluated their preference level for each gesture candidate using a 100-point scale after watching a video showing gesture candidates. If the average preference score for the gesture was evaluated higher than 50, the gesture was defined as the preferred one. This study performed statistical analyses to further investigate differences and similarities of the preferred gestures for each command. In addition, the top two gestures with the highest score among the preferred gestures were analyzed. The characteristics of the preferred gestures were also suggested by age.

Objective: This study aims to identify the differences of preferred gestures for devices in kitchen and bathroom according to gender and age. Background: Recently, various studies related to gesture interfaces have focused on designing intuitive gesture commands to enhance the usability of the interfaces, and they have tried to derive gestures from users. However, there are few studies to identify the differences of preferred gestures according to age or gender. Method: 32 participants were recruited with consideration of various ages and gender. In the experiment, participants evaluated their preference for each gesture candidate using a 100-point scale after watching each video showing gesture candidates. Two criteria were used to select preferred gestures for each command: average point of preference (above 50) and the frequency selected as the most preferred gesture among gesture candidates (above median). Results: As a result, although several gestures were equally preferred among the different age groups and gender groups, different characteristics for preferred gestures were identified according to the groups. Conclusion: To enhance the usability of gesture interface, the preference properties for gesture commands according to age or gender should be considered from the beginning stage of designing gestures. Application: The results of this study can be used as a guideline to design user preferred gesture and can contribute to alleviate ‘Digital divide’ phenomenon.
Developing UX Elements for Disabled People based on Literature Survey

The purpose of this study is to identify the elements of user experience (UX) of disabled people. We focused on the UX of mobile products. Many researches about the user experience have been conducted to provide the users with a wealth of experience, but those researches have been conducted only with general users (i.e., non-disabled people). In comparison with non-disabled people, disabled people have different abilities to sense or to act, so their experience with products or services also can be different. To make a product or service for disabled people with the consideration of their experience, understanding the UX of disabled people should be required. In this study, to understand the UX of disabled people, we identified UX elements of disabled people. We analyzed previous studies on usability for disabled people and UX elements for general users. A total of 3 elements, 20 subelements, and 75 subconcepts were derived for the UX element of disabled people. This study can serve as useful criteria for development or evaluation of product or service for disabled people.

Objective: The purpose of this study is to identify the relationship between characteristics of devices and user-preferred gestures. Background: Recently, studies related to designing gesture commands have tried to derive gestures from users to enhance the intuitiveness and learnability of gesture commands. However, there are few studies to identify the relationship between characteristics of devices and user-preferred gestures. Method: 44 functions for 11 devices were used in this study for evaluation, and they were divided into two sets. 32 participants evaluated gesture candidates for the one set, and the other 32 participants for the other set in terms of preference using a 100-point scale. The user-preferred gestures for each function were selected based on the two criteria: above 50 point in the case of average for each gesture, and above median in the case of the selected frequency as the most preferred gesture among the gesture candidates for each function. Results: A total of 10 relationships between characteristics of devices and user-preferred gestures were derived. Conclusion: This study can give insights to design gestures for the similar functions with this study’s target functions. Application: This study can be used as a guideline for designing gesture commands.

Recent studies in gesture interfaces have focused on enhancing the naturalness of gesture vocabularies by utilizing users’ experiences related to a command. However, the previous studies lack methods for organizing the user-defined gestures in a systematic manner. It is difficult to identify the important characteristics of the user-defined gestures for commands. The users’ intentions of deriving a specific gesture for a command could be misinterpreted by the researchers. We propose a three-dimensional hand gesture taxonomy to resolve these issues. Further, we organized the user-preferred gestures that were acquired via two experiments. By subdividing the elements of each gesture, we were able to develop a new method for analyzing the important characteristics of gestures. This study proposes a novel and systematic approach to quantifying user-preferred gestures.
