A Video Analysis of Eye Movements during Typing: How Effective is Handwriting during Note-Taking Tasks?

Keyboard input for non-alphabetical languages, such as Chinese and Japanese, is problematic because it is labor intensive and imposes a high cognitive load. In our previous work, we measured the effectiveness of handwriting during a note-taking task in Japanese, and found that the input speed during note-taking was higher by hand than by keyboard. The results also showed that the quality of notes taken by hand was higher than that of notes taken by keyboard, and this might have been due to the higher cognitive load during typing. In addition, observation during the experiment revealed several problems subjects faced in the keyboard input task. To evaluate the significance of these observations, we had to obtain quantitative evidence through further study of participant behavior. Therefore, we repeated the experiment, this time with video analysis of the keyboard subtask. By analyzing the participants’ eye movements and their behavior throughout the keyboard subtask we obtained quantitative evidence to support our findings from the previous study. Here, we describe this experiment and our findings in detail

Text Touching Effects in Active Reading: The Impact of the Use of a Touch-Based Tablet Device

International audienceThis paper describes experiments examining the effect of touching interaction with text in active reading through evaluating the impact of the use of a touch-based tablet device. The first experiment compared the performance of proofreading when using paper and when using a touch-based tablet device. Results showed that participants detected more errors when reading from paper than when reading from the tablet device. During reading, when using paper, participants frequently performed the interaction of text touching, such as pointing to words and sliding their fingers or pens along sentences. This fact suggests that touching interaction with text plays an important role in proofreading tasks. To verify this hypothesis, we conducted a second experiment in which participants proofread documents with constrained interaction with paper. Results showed that they detected more errors when they were allowed to interact with text freely than when they were not allowed to interact with text. Considering these results, we discuss practical implications to effectively support active reading with a touch-based tablet device

Truly Useful 3D Drawing System for Professional Designer by “Life-sized and Operable ” Feature and New Interaction

Abstract. “Media ” is an artifact that expands our creativity and intelligence. We have been studying the use of “Rich Media ” to support creative and intelligent human activities. Specifically, for over ten years we have focused on the 3D space as one of “Rich Media ” and developed many 3D sketch systems that support the design of 3D objects. However, their long-term evaluation has revealed that they are not used by designers in real fields. Even worse, they are treated as if they were just mere attractions in an amusement park. The fundamental problem is the lack of the indispensable function for 3D space. In this paper, we propose new design principles, “life-size and operability”, which make the 3D sketch system truly valuable for the designer. The new 3D sketch system is designed on the basis of “life-size and operability”, developed, and evaluated successfully
