METHOD TO ANIMATE ON A COMPUTER SCREEN A VIRTUAL PEN WHICH WRITES AND DRAWS
No full textA method to animate on a computer screen a virtual pen which writes and draws on a virtual blackboard in order to simulate a real pen writing on a real blackboard. Graphemes and drawings (50) are created by specifying a subset of knot points (106, 107, 108, 109) from the set of points forming the lines (50) to draw. All the attributes concerning the knot points, as coordinates (201), pauses, speed, thickness, etc., are stored in a file. Subsequently the user types on the keyboard the word to write or selects from a list the drawing to draw.; At this point all the attributes of the knot points of the graphemes to write or of the drawing to draw are retrieved from the file and interpolated, and the data obtained are used to animate a virtual pen in such a way it writes and draws looking likea real pen, pausing at the sharp angles, detaching from and landing on the writing surface of the virtual blackboard, varying the thickness and the speed of drawing, using block letters or joined-up writing
METHOD TO SYNCHRONIZE AUDIO AND GRAPHICS IN A MULTIMEDIA PRESENTATION
No full textIn a multimedia presentation, having speech and graphic contributions, a list of graphic objects is provided. Each graphic is associated to a graphic file capable of being executed by a computer to display a corresponding graphic contribution on a screen. A speech file comprising a sequence of phrases is also created, each phrase comprising a speech contribution explaining at least one graphic contribution associated to a respective graphic object. Then, an arrangement string is created obtained as a sequence of a first graphic object and a respective first phrase, and then a second graphic object and a respective second phrase, and so on up to completion of all graphic objects and phrases of said list and of said speech file respectively. A processing speed for displaying the graphic objects is chosen
