Using EasyCanvas Pro with Expresii

10/12/2020

Comments

 
Apart from Duet Display  Pro,  there's also Easy Canvas Pro from DEVGURU Co.  in   Korea that allows you to use your iOS or Android device as pen display to your desktop apps.  Yes, it's like connecting a Cintiq to your desktop, but you have the option to go either wired or wireless.  You can use a tablet like   the iPad or  the   Samsung Tab S3   or even your Samsung Note 10 phone.  It'd be  a great solution if you already own one of those devices.

We just tested  their newly released   EasyCanvas Pro for Android . I own a Samsung Note 8 with S Pen, which supports both pressure and tilt, so I used it in this test.  Normally, you should use a tablet instead since a phone's screen is very small for painting.
I found the wired connection gives satisfactory performance. When using 2.4GHz wifi, the delay is rather noticeable.   Unfortunately, I don't have a 5GHz router here so I can't test 5GHz   performance. The Samsung device shows the 2.4GHz wifi  giving 144Mbps, while my test desktop is connected to the wireless router via cable.  My desktop screen is at 4k and my phone is set at FHD+, so Easy Canvas has to resample the 4k screen capture and that's another source of latency.   

We hope DEVGURU can support G-Sensor data and hover in the future.   G-Sensor can be used for surface tilt to direct the paint flow, and hover is good for users to see the pen posture before hitting the paper. This is important for Eastern calligraphy, if not for painting in general.
