Functionality of SAM PuttLab
Data registration
The positional data of the movements is recorded using the SAM
MotionAnalyzer movement registration system. In this measuring
system the positions of miniature ultrasonic transmitters are
sampled at a maximum frequency of 210 Hz (total for all markers
used) at a spatial resolution of about 0.1 mm. Before data analysis
the raw positional data is filtered using specially designed filter
procedures.
Automatic segmentation
During data recording a data tracer is automatically identifies
single strokes from the data flow. For each identified valid stroke
an automatic segmentation is calculated to divide the movement
into relevant movement segments. The movement data and the
segmentation information are then stored on the computer. Based
on the data segmentation up to 28 different movement parameters
and their distribution in movement repetition can be analyzed.
Analysis
SAM PuttWare software includes extensive graphical and statistical
tools to analyze the movement data. Single strokes can be easily
selected from the recorded data. The movement characteristics
can be inspected in different plots. All data values and differences
are displayed on the screen and can be saved to a file.
Graphic Reports
SAM PuttWare provides powerful graphic reports with multiple
graphs, texts, and boxes. The high resolution graphical reports
allow clear illustration and documentation of the individual
movement performance. Graphic reports can be created for screen
display or for print out and are available for different performance
levels. The reports can also be converted to PDF-format and saved
to file.
Competence profiles
A special software module allows displaying the data in bar charts
on uniform scales. The transformation of the parameters to z-
values allows a direct comparison of movement performance for
