The device includes a Samsung tablet specially configured for target editing. The targeter allows you to edit targets or sets of neuroactive targets in A4 format up to A2 format (equivalent to 4 A4 or 2 A3). Available formats: A4: direct printing from the application. A3: simple printing or assembly of 2 A3 to obtain an A2. A2: either by assembling 4 A4 sheets generated via the application, or by assembling 2 A3 sheets, or by editing an A2 target ready to be printed at a printer. Levels of analysis of the result on target. Basic analysis (visual and immediate) Direct display of impacts on the digital target. Automatic counting of shots in the targeted area. Highlighting of major deviations. Intermediate analysis (accuracy and consistency) Calculation of the center of gravity (barycenter). Measurement of the average distance to the center (overall accuracy). Evaluation of the dispersion and consistency of the grouping. Length/Height ratio (L/H). Advanced analysis (statistical and adaptive) Clustering: automatic grouping of impacts into homogeneous clusters. Detection of systematic deviations (e.g. tendency to shoot low-left). Highlighting of typical errors: certain subgroups within a global grouping may reveal a recurring error (posture, aim, etc.). Multivariate analysis (expert level) Mahalanobis distance: measurement of the deviation of each shot from the global grouping. Detection of outliers (isolated shots) which may represent a threshold of loss of control. Evaluation of the internal consistency of the shot. Comparison between several series of shots.
