  • Predictive Input Interface of Mathematical Formulas
    2017
    Co-Authors: Yoshinori Hijikata, Keisuke Horie, Shogo Nishida
    Abstract:

    Currently, Inputting mathematical formulas into a document using a PC requires more effort by users than Inputting normal text. This fact inhibits the spreading of mathematical formulas as internet contents. We propose a method for predicting user’s Inputs of mathematical formulas using an N-gram model: a popular probabilistic language model in natural language processing. Mathematical formulas are usually presented in hierarchical structure. Therefore, our method incorporates hierarchical information of mathematical formulas to create a prediction model. We try to achieve high prediction accuracy of Inputting characters for mathematical formulas.

  • The Input-Interface of Webcam applied in 3D virtual reality systems
    Computers & Education, 2009
    Co-Authors: Huey-min Sun, Wen-lin Cheng
    Abstract:

    Our research explores a virtual reality application based on Web camera (Webcam) Input-Interface. The Interface can replace with the mouse to control direction intention of a user by the method of frame difference. We divide a frame into nine grids from Webcam and make use of the background registration to compute the moving object. In order to make this technology apply to 3D virtual reality system, we use the Virtools Dev to build virtual scenes and the Microsoft Visual C++ to build this Interface. We also use the MySQL database management system to access users' data and the displaying data. We implement a number of Building Blocks (BB) to support Virtools Dev for using the database management system and the Webcam Input-Interface in this composite system. The results of research are expected to the digital content industries such that users can easy to use the Input-Interface to control browsing the virtual reality. Our system can supply interactive digital content, photographs, and access the questions from the database management system. In addition, the system provides the browsing mold, the question mold, and the course content describing mold with the Input-Interface. In order to explore the intention of users for using the system, we design the questionnaire based on the technology acceptance model (TAM). In our empirical study, we find that perceived playfulness is positive association with attitude toward using. Interface style is positive association with perceived ease of use.

  • IIH-MSP - The Input-Interface of Webcam Applied in the Digital Content Interaction

We divide a frame into nine grids from Webcam and make use of the background registration to compute moving object. In order to apply to virtual reality system, we use Virtools Dev as the platform to build this Interface by Microsoft Visual C++. We implement a number of Building Blocks(BB) to support Virtools Dev 3.0 for driving Webcam Input-Interface in this composite system. The result of research is expected to digital content industries such that users can easy to use the Input-Interface to control browsing virtual reality. Our system can supply interactive digital content, photographs, and access the questions from the database system to request the user responding. In order to explore the acceptability of users for the system, we design the questionnaire based on the technology acceptance model(TAM). In our empirical study, we find that the perceived ease of use from TAM between the skilled computer users and the unskilled ones are significantly different and most subjects think the system is perceived usefulness.
