What are the optimum experiment settings that I should use?
MovAlyzeR is a general purpose movement recording and analysis system for handwriting and drawing movements. MovAlyzeR enables professionals in the medical, gerontological, rehabilitation, ergonomical, psychological, psychiatrical, physiotherapy, forensic, and educational fields (among others) to obtain immediate, accurate recording and analysis of a person's handwriting, drawing, or other 2-dimensional movements. more..
MovAlyzeR can record, process and analyze data using a mouse, tablet pen or a gripper. ScriptAlyzeR and MovAlyzeR can record mouse and tablet movements, whereas the GripAlyzeR records the gripper (or compatible external analog device) movements.
Yes. The MovAlyzeR installation file can be downloaded from the downloads page. Detailed requirements and instructions are also presented on this page.
To set up and run a basic experiment, refer the tutorial with easy steps, examples and snapshots. Also available are precise steps on the online help introduction pages for each program, with cross-referenced links to the specific topics on each step.
Per trial, the processed data such as velocity, acceleration and jerk can be viewed in a text file and charted. MovAlyzeR parses movements in to segments/strokes. The segmentation points can be viewed in a file or shown on the charts (red circles).
For each segment/stroke, features such as start time, duration, vertical length, velocity, acceleration, normalized jerk etc. are calculated. These data are available in a text file per condition and the charts can be viewed per trial.
In addition, consistency error data and consistent data are presented in a text file.
A summarized data and summarized error file are available per experiment, which give the data summary for analysis purposes.
Yes. Consistency checking can be applied to the trials and specifications can be set per condition. Based on the type and parameters specified, (e.g., length and direction of stroke), trials are accepted or rejected. The output consistency error file lists the reason a particular trial was rejected. The error summary file per experiment shows the corresponding statistics.
The Acquire button the Device Setup Wizard and the Experiment Properties > Input Device window is the most accurate way to retrieve Sampling rate and resolution from the device driver.
The input device settings per experiment (e.g., sampling rate and resolution) should be specified as per the device used to collect data, and updated everytime the input device is changed, to yield correct results. Run experiment settings should also be specified according to the required timeouts. For a basic experiment, the other settings could use the default values. More..
The digitizer and display areas usually vary in size. The entire/portion of digitizer could be mapped proportionally to the entire display or recording window in MovAlyzeR. In the latter case, the size of the recording window is set to the size of the tablet. There are simple tests or precautions that can be done before the experiment is run. More..
This implies that either the digitizer driver is not installed on the computer or the driver needs updating. In order to use the digitizer tablet, the appropriate driver needs to be involved. (If you have a Wacom tablet, check http://www.wacom.com for the driver software). Please check your computer to see if the driver is installed and then retry opening the application.
Yes. MovAlyzeR provides various options to chart the analyzed results of the trials. Although not extensive, this feature provides the user with a quick review of the results, which can be used to make corrective changes to the experiment or data collection. Upon satisfactory results, the data summary text file can be imported to more extensive statistical analysis programs, such as SPSS. More..
Yes. You can import MovAlyzeR, Accelerometer, Oasis, Eyelink and Gripper data in to MovAlyzeR for analysis. You can export MovAlyzeR trial data in the form of text files. An experiment can also be exported with or without associated data to be used by another user or on another computer. For more see File > Export in MovAlyzeR.
Yes. You can extract a handwriting sentence (set of words or strokes) in a trial in to individual words by setting the appropriate word extraction properties in experiment settings per experiment. The individual words would be analyzed as seperate conditions and sub-trials will be generated accordingly. More..
The targets and recording can be made real size using the appropriate mapping settings. If such settings are chosen, a target element/recording would occupy the same size on the tablet as shown on the display. This would be highly efficient for trials with visual feedback. More..(including print real-size)
If you are using the mouse to collect data, specify that in the input device settings of the program (Settings > Select Input Device). Also, the appropriate sampling rate and resolution should be specified in all the corresponding Experiment Settings > Input Device Settings to avoid incorrect calculations. The sampling rate and resolution can be estimated while using MovAlyzeR. More..
Yes. Read External Processing Support in MovAlyzeR to learn how.
