Traditional courseware is lack of humanity. Proposes to use Agent technology achieve the humanized design in courseware. Microsoft Agent with its lively and clear human features has had a significant influence upon traditional human-computer interaction. This paper introduces the related technologies of Microsoft Agent, and discussed the realization of the principles and the design process of the Microsoft Agent in authorware . The paper gives the Agent script design structure, the human feedback of humanized courseware and the notes in the process. Microsoft Agent enhanced the expression and presentation effect of courseware by lively images of anthropomorphic expression, speech and action.

Computer Interaction

Human Computer Interaction is a relatively new field. It has borrowed theories, techniques, and tools from such diverse disciplines such as computer science, management of information systems, sociology, anthropology, psychology, and design. The Web design process needs to evolve in order to include the constructs and tools provided by multidisciplinary research. Culture has been proven to have a direct influence in the way a Web site can be both evaluated and designed. In order to attract and retain users, electronic government Web site designers must acknowledge that culture plays a key role when it comes to user acceptance. The best way to approach the users, who in the case of an electronic government are the citizens, is a citizen-centered approach that must be incorporated into the Website design process.

The modeling of human movement is vital for a complete understanding of complex human–computer interaction. As three-dimensional collaborative tangible user interfaces (TUIs) evolve, research is needed to understand how people physically interact with each other within a virtual environment. Previous study of physical collaboration in virtual environments has utilized Fitts' law to model gross upper-extremity movement in a passing task. However, no study has modeled passing tasks that require precision grasp with the human hand, an important feature of human–computer interaction in TUIs. The purpose of this study was to evaluate the validity of Fitts' law in modeling movement time for a precision passing task in a 3D TUI, and to assess the coordination between passer and receiver using kinematic parameters. In this experiment, 12 participants (six male, mean age 22.6 years) performed a prehensile passing task within a desktop virtual environment. Results detail the kinematic events required to achieve the necessary temporal and spatial coordination specific to the passing task. Further, results indicate that Fitts' model does not adequately explain movement time for this task (R 2 = .51). This finding challenges the external validity of previous results. We argue that the task-specific complexity of human neuromotor control should be considered when using predictive models in 3D TUI design.

This paper summarizes our study of tactile languages in humancomputer interaction. We intended to analyze how the choices made during the design process of tactile vocabularies would affect the user performance on an interactive task. Therefore, we have developed and tested different sets of tactile signals for aid navigation in virtual environments. It leaded us to fashion a novel approach for vibrotactile prefixation. Through this experimental-driven study, we attempted to effects of multisensory stimulation, perception, learning and interpretation of tactile sequences, and masking caused by multiple vibrations in a same locus. The presented results should be useful for other designers to produce usable and expressive tactile interfaces.

Traffic accidents,which are caused by faulty tires, have caused great losses to people's life and property.At present, generally,researching prevention measures of tires puncture are through real car tires tests around domestic and international. I made a research about automobile tires puncture performance in a virtual driving environment ,to build a virtual car tires puncture research system in combination with the VC platform and EON simulation software, and used the Logitech G25 controller to manipulate virtual cars, then real-time human-computer interaction was achieved.

- Virtual reality aims at immersing a user in a virtual environment. Dedicated virtual reality technologies of human–computer interaction enables linking the user and a virtual environment in capturing the user's motion. Our primary purpose is to improve communication between the students, especially the team members in STEM schools in Egypt. The application supports students in the capstone project for each grade. It is supported by tools to make a simulation for the project. Also, it is supported by a virtual reality headset. As we mentioned, VR is used in many fields, and it isolates the person from the surrounded environment altogether. VR is used instead of Anesthesia because of its effect in isolating humans from the surrounded environment. That will increase communication and concentration between the team members and make them feel that they are in an actual meeting. Every person will have an avatar in the application represent him. This avatar will translate every member's motion in the meeting by the sensor in the VR headset. A mic supports the VR headset. Every team will have a specific room, this room is where they can make all meetings, and all the work, achievements, and updates of the group will save in this room. Also, the application work as a director for the work

This article is about the creation of tools and technologies that support physical, mental, social and emotional wellbeing. Students from a polytechnic institution were challenged within a human computer interaction discipline, to set an idea and to present its design process. The objective was to create something using technology to improve people quality of life. The main goal of this article is to settle some of the reasons that lead to important and interesting outputs to the amount of unfinished or unavailable applications to be used by those who need it.
