I frequently use my laptop in this position of the person in the photo, laying on my couch or bed. The touchpad is very close to the edge of the laptop, so any "gestures" requiring multiple touches (scrolling, swiping, etc) often get screwed up because my stomach is "resting" on it and providing a point of touch. Then I have to either get up or push the laptop up onto my leg to use the gesture I wanted.
Normal mouse movement works fine though.
How can I still lazily use my laptop in comfort without my belly interrupting the touchpad?
