Help with swipe up and down

[pouralise]

Hello, I want to creat a visualization like this. But I meet a problem when I try to swipe on the screen. When I touch a point on a object (or image), I can't swipe up or down, example when I touch in the red region. I can only swipe up or down when I touch a point outside the object, example when I touch to the green region. How can I fix that so I can swipe anywhere on the screen?
Thank you.

I'm sorry if it's hard to understand what I mean. I have uploaded a video to show the problem. It's very hard to scroll to room 7 and below
