Video analysis technologies provide nowadays several capabilities that allow for a new dimension in the field visualization of the phenomena of motion, as well as new methodologies for studying them, that foster studentís high cognitive skills.
In this paper we present the design and development of a VideoJavaLab (VJL), a Java application which combines the capabilities of video measurements, with the flexibility of web application. Using VJL, students can view real life phenomena of everyday life, sports, or lab videos, and analyze motion. In particular, student can take measurements with a click on his mouse, experimental data are recorded and at the same time displayed as graphs or tables. Student can go back or forth from frame to frame, examine the motion, repeat or correct a measurement and interrelate real motion to each graphical representation in multiple graphs.
VJL can run in a typical web browser (without any plug-in required) and the overall design includes a variety of HTML tools, in connection with online activities and underline theory in a modern HTML design. Video optimization techniques, make VJL suitable for a web based learning.
