How to make the finger in a generated clip actually tap your app icon
Tell Vizard Agent the tap misses your app and it will fix the screen instead of the hand. It pins a flat home screen onto the phone frame by frame, measures where the generated fingertip actually comes to rest, and rearranges the icons so yours sits exactly under it, then adds the press feedback on that spot.
What do you type into Vizard Agent?
Say which frame shows the miss and what should be pressed. Regenerating the shot to get a thumb that lands on a small icon is a gamble that costs a generation each time, while moving a flat icon under a thumb that already looks natural is a measurement.
The tap on the icon isn't right. Here it didn't press our app at all. Blur all the other apps from the moment they appear until they disappear.
What does Vizard Agent actually do?
It treats the phone screen as a surface it controls and the thumb as fixed. The generated hand moved the way it moved; everything under it can be redrawn to agree with it. In the session behind this article it:
- Pulled frame strips across the tap and saw the thumb touch one spot briefly, then slide and rest over a different icon.
- Built the home screen as a flat image and tracked it onto the phone in every frame with optical flow, putting the thumb back on top.
- Transformed the frames around the press back into the screen's own coordinates and measured where the fingertip settled.
- Moved the app's icon to that exact position, blurred and dimmed the other apps, and added a glow growing from under the thumb at the press.
- Kept the other apps blurred for the whole time the home screen is visible, as asked.
When does this not work well?
When the thumb never settles. If the generated hand keeps sliding across the screen, there is no single point to put the icon under, and a new generation is the honest fix. A phone held at a steep angle or half covered by the hand also gives the tracker too little screen to lock onto.
Common questions
Why does the generated thumb miss my icon? It rarely lands precisely. Vizard Agent moves the icon under it.
Do I need to regenerate the shot? Usually not. Vizard Agent redraws the screen instead.
Can it hide the other apps? Yes. Vizard Agent blurs them for as long as they are on screen.
