By popular demand, this version adds the ability to save the unique artwork created by the NHPs while they are using the “finger paint” feature.  We’ve collecting artwork and creating a gallery(see below) of the clever work by our primary users!  This is a full and complete version (not a patch).  Please go to Windows/Add-Remove programs and remove any previous versions of the ChoiceSolo app (V2.1.1) before running this installation file.  New users will be able to run in trial mode for 10 days.  Existing users should be able to use previous license files to register this version for full use.  Contact Bill if you need help!

As soon as your NHP begins to tire of their current content options, it’s easy to swap in new choices! 


Keep an eye on your NHP’s activities, even when you’re not there.


Built-in history collection records your NHP’s actions with a timestamp, then stores the data in a file you can download and analyze later.


The system is compatible with any Windows-based tablet, 10” and up.


The impact-resistant case can be customized to fit the tablet size that works best for your NHPs and will easily mount to your existing housing. 


“We have been chugging along out here with the monkeys! We are using our tablets out the wazoo! Our monkeys have gotten pretty well oriented with these and we have set up each tablet to have different videos so they are getting a large variety. We have also been putting together data of what each monkey enjoys doing and one of our technicians is going to begin a little study to see if the animals have a favorite video or song (based on previously collected data) and if she moves it around within the system will the monkey search for it!”
