New features for Pupil Capture
Adjustable timebase for capture. We've changed the reference time point for timestamps to now.
Screen marker based accuracy test. Enables one to evaluate gaze accuracy and precision. (See screenshot below)
Added option to disable the coarse pupil detector, as it may fail when the subject wears mascara.
Detector variables have be tweaked to improve detector effectiveness and speed.
Camera capture is now more robust. If the camera should fail while Pupil Capture is running, (e.g. if a USB cable is disconnected) the software will clean up any ongoing action (recordings etc.) and do a proper shutdown so that data is preserved.
Capture app starts even without cameras connected. When cameras are not detected Pupil Capture software still starts, but respective windows without cameras will display a test pattern (random color squares).
Added option to disable screen updates for world and eye window. This helps weak systems record without dropping frame rate.
Retina screens are now supported. The mouse cursor is no longer offset.
Pupil Server to OSC bridge script. After getting a lot of requests for OSC streams, we made a small script to allow Pupil to interface with OSC devices. Script can be found in this gist.
Performance improvements for Pupil Capture
Various small improvements have been made as we are trying to make pupil capture run on smaller and cheaper laptops. Using Ubuntu 13.10 we are now able to make recordings with Pupil Capture on a 2010 11inch Macbook Air. When disabling screen updates we are no longer dropping frames. The CPU of our test machine is a Intel Core2Duo SU9400 -- this means that Pupil should run on any "i" type intel processor now.
This test was done using Linux, we know that some internals on MacOS are slightly less efficient so you may need a little bit more steam if you run MacOS (any recent Mac will do fine though.) If you have tested minimum specs for Windows please send us an update!
New features for Pupil Player
Marker based surface tracker, has been added but still need some visualization methods
Added a simple fixations filter. Current simple filter, although not scientific, will make the data look better by filtering data based on distance between points. We are currently working on a proper fixation and saccade classifier -- stay tuned!
Added cross as gaze visualization.
Added a simple / hacky gaze offset plugin.
Added pupil server plugin.
Small fixes and improvements
Pupil Player now closes via GUI.
The capture class now has proper exceptions
Texture upload have be optimized for capture and player
Pupil Player meta info reader is more robust
Fixed a bug that messed up the log files on MacOS
Fixed a bug that led to crashes when entering fullscreen mode.
Pupil Player now avoids export overwrites by adding a timestamp to the out file name
Many small GUI improvements and more documentation strings
Player plugins can no longer make permanent changes to recent pupil positions.
Fixed a bug in capture selection list on Linux
Pupil player plugins now remember their GUI state.
Added support for Logitech c510 camera
Pupil Player exporter now logs is a more proper way
Various minor fixes and tweaks
Ubuntu has been working quite well for a while now, so no real news here.
Various fixes have been made to the MacOS bundle for player and capture. Everything should work now. (If not please let us know!)
