Abstract
WordPad multimedia applications in teaching, the classroom can greatly enhance the amount of knowledge to impart, the speech made by the review can be stored as information on students; can accept students according to ability to further refine the knowledge, the classroom can express their ideas and inspiration; simulated chalk, blackboard excellent teaching methods at the same time the traditional model, but also reduces the labor intensity of teaching people. Multi-media teaching tablet users through a dedicated stylus to write in a specific area on the board and grass painted to simulate the writing on the blackboard model, regardless of speed or accuracy will be far more than the mouse. The use of this product can quickly simplify the writing symbols, schematic form, expression, process knowledge and methods, such as the site of expression, which is the keyboard, mouse, it is difficult to achieve flexibility. Tablet is an integrated mechanical, software, communications and electronics, such as an organic unity to the domain. As a team, we need to complete the task is to: (1) the use of VC + +6.0 software products to edit their own application interfaces to make their own style, with hand-written user-friendly information exchange between the board to avoid interference. (2) the use of electromagnetic pressure flu-type, use its good performance, so that users can use it to write to smooth and improve feel. (3) to reduce the voltage requirements of a stylus on a high tablet work to improve stability. (4) the realization of the USB interface, tablet computers and good communication to improve the tablet sensitivity and accuracy. (5) regional development activities to achieve drawing and writing to complete the same interface. (6) of the shortcut keys to frequently used buttons to improve the operability of the tablet. (7) tablet stylus nib is the moving parts, as a result of long, high-frequency and small nib, and its relatively short life in general, we have to improve from their machinery. As a team, my tasks are: 1. The existing principle of tablet research 2. The existing circuit board handwritten 3. Homemade circuit tablet research, experimental design and recording 4. Designed to improve the button functions in the hardware circuit of the improved scheme
