Introduction Technological tools allowing an accurate observation of sport gesture are still very often out of reach financially, materially or difficult to operate for the non-specialist in these technologies. Hypotheses Computers, their peripherals, notably the video acquisition cards, the means of storage, and the current software packages (spreadsheets and tools of presentation assisted by computer) would allow making tools of observation simpler to operate as they are now commonly used. Materials and methods The spreadsheet is a tool which allows to count and to show at the same time. By dedicating keys to events or criteria to be observed, it is easy to count these observations and to show them in real time. We conceived two applications: - In the first, the observations are to be made in real time. It is "to click to get involved". At the end of the digitized sequence, the user can compare his own statement with the expert's. This comparison of statements is in fact the moment of training. In the example 1, the user should record by pressing on dedicated keys for that purpose, the advantages and the penalties which he observes along with the digital video sequence Example 1 - In the second application, the same principle allowed to collect specific actions then to record them. They are afterwards presented in a specific way. The observations are to be done a posteriori; it is what we call "to click to see". The presentation can take different shapes. Either the statement of the actions explains the actions seen in the video as in example 2, or the actions are presented on a graph which allows the interpretation as in example 3. Results The three examples are used by students in physical education (STAPS). We presented both last examples in the frame of classes preparing to the teacher's first degree in judo or in training courses. With the example 3, we work with 10 young judokas. The results are in progress and try to show the use and the evolution of their attacking system in judo throughout this sport season. Discussion and conclusion The time length required for the completion of the first example is significant. The creation of the graphs for the expertise is long. The user should be rigorous and of an irreproachable attentiveness. Both following examples are easier to realize, it is a question of understanding the principles of organization. On the basis of these examples, users become actors of their training project. We must admit that both last examples are still the most commonly used.
