<p><P>PROBLEM TO BE SOLVED: To enable a person to intuitively and efficiently understand measured velocity vectors. <P>SOLUTION: After measuring velocity vectors of toner particles flying in a minute void formed by a particle carrier 2 and an electrostatic latent image holder 4 by PTV from two image data picked up by a CCD camera 10, an image processing device 12 converts the measured velocity vectors into image information and displays it on the screen of a display device 14. Velocity vectors corresponding to the position of a cursor 34 out of the measured velocity vectors are further converted to generate tactile information, and a presentation part 24 is driven according to the tactile information to present a user with the velocity vectors in the cursor position tactilely. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
