Introduction to virtual Buton in Augmented Reality

Posted: 12 Jul 2020 10:00 PM PDT

Virtual Button is a clickable on the Image Target using which we can interact with the Image Target.


Six (6) important factors to consider

1. Size  : Virtual Button should ideally have an rectangular shape.

2. Placement of Virtual Button : Area's on image Target with maximum or many yellow dot's are called featured area's.



3. Virtual Button should not be placed on Borders of Image Target.

4.  Multiple virtual button's should be placed in ROW arrangement



5. Sensitivity of Virtual Button  : LOW MEDIUM and HIGH

6. Texture area on which virtual button is placed
