• On all systems sound can be played with ffplay (and on mac cannot be played with gstreamer anymore).
• Rewritten developers credits on about.
• Need to confirm on exit the program (needed on the new interface because exit can be done easier by mistake).
• Session load/edit/delete/import moved to main window to have more space and be easier to use (specially on tactile interfaces).
• On preferences / appearance, shown options recommended for small screens.
• 4 modes are shown at start (reaction time and other is hidden but can be shown/hide pressing a right/left arrow button).

Force sensor

• Elastic exercises with elastc bands/stiffness management.
• On elastic exercises, software shows position, speed, acceleration and power.
• Repetitions are automatically detected:
• … plot according to minimum force on (not elastic) / minimum displacement (elastic).
• Force/displacement repetition criteria is defined on exercise creation and have a default on preferences window.
• can be zoomed clicking with mouse.
• Repetition number is exported with the rest of the data.
• All the force sensor mode now uses database
• All the old data is automatically imported to database to be managed properly.
• The management of the data is much better now and solves problems like the change of the name of the person who performed the test.
• Tests can be loaded, change the author, deleted, removed, change any params of the exercise or capture mode, and recalculated to have new results (and update on them on database).
• There’s a management of deleted exercises to not delete the tests with them (like on encoder).
• Session load window shows force sensor tests.
• Show all persons tests window shows force sensor tests.
• Webcam support: capture/play on force sensor
• New feature: capture with scroll (default and configurable on preferences). This mode it also implements the feedback rectangle.
• Can capture using absolute or inverted values (and can be recalculated).
• Several changes on exercises:
• Depending on exercise configuration it can be shown resultant force or raw force detected by the sensor.
• Exercises now use percent of body weight, so results in N will change if you select that exercise option.
• Exercises have new option: tare before capture that makes a tare at the beginning of each capture. Useful for exercises like hamstring force on leg at some height and fixed to a bar with the strain gauge. In this exercise, the automatic tare will remove the weight of the leg.
• Added laterality buttons.
• Can save comment.
• Feedback rectangle shown transparent.
• on RFD automatic graph, it is displayed mean error of the model, exercise name and date.
• On general analysis, sliders and buttons have changed and all data is shown on the interface (and not in the graph potentially hiding the lines).

• At analyze has AB, first/last buttons (like on encoder).
• On preferences force sensor it can be selected how much seconds will display the capture area (default 10 seconds).
• Labels Max/Current/Min at right and better formatted.
• Force capture drawingarea can be resized at anytime and graph is redrawn.
• Capture graph: Better vertical space while capturing.
• Force sensor capture graph is ok now for really low forces.
• ForceSensor tare/calibrate do not need to check for sensor 0.4, much faster now on this firmware update. Also 0.4 makes a tare 5 times faster.
• Graphs line width can be changed on preferences (nice for big screens or bad viewing conditions).
• Force sensor can read triggers on capture (not display them yet).
• Force sensor connect is more robust.
• Show label at checkVersion (of the firmware) from menu.
• Messages of different actions are more easy to understand.
• Minor fixes on analyze buttons sensitivity and also on drawingarea and save signal button.

Encoder

• Capture bars can have a secondary variable.
• This second variable is by default range absolute (can be changed on feedback window).
• This variable can be activated or not.
• Saving repetitions has two new modes “bestn”, “bestn consecutive”, where n repetitions can be saved automatically.
• Saving repetitions can be done clicking them on the bars graph.
• On inertial, end capture also when 2*inactivity endTime since last phase. This helps to automatically end the inertial capture when inertial machine is still slowly rolling.
• Improvements on loss calculation
• Loss is always calculated on concentric.
• Loss is calculated always from best repetition to the end of the set.
• Loss is displayed on graph with info and an arrow.
• Loss does not use last repetition if it’s range of movement is low (range smaller than 70% of range of the best repetition).
• Encoder feedback can be only eccentric or concentric phase. Unwanted phase is shown as gray bars.
• Eccentric overload drawn with green arrow (if achieved).
• Historical feedback can be also on mean speed and mean force.
• Added RPD calculation.
• Added RFD calculation.
• Added Work calculation.
• Added Impulse calculation.
• On loading a set: can be changed the performer, the comment or can be deleted, all without the need of use second mouse button (good for tactile screens).

• On analyze current session, at select repetitions is shown also mean speed and mean force (it was shown only mean power).
• New method to display the bars, should be faster specially after 1st capture.
• On analyze / superpose graph shown end of propulsive phase.
• Encoder exercises can be renamed.
• Eccentric ground phase starts when force >= 0 like in paint (not >= weight).
• Added ‘e’ or ‘c’ on ecS set/repetition export to csv.
• Fixed encoder inertial feedback historical.
