I'd say it's very hard to make a good product if it doesn't solve a problem you are personally facing. For example, we wanted to do a usability test, but it's quite a hassle to find enough people to do it. I thought how more and more laptops had integrated cameras. So I came up with the idea of a service that lets me pay $5 to random people on the Internet in exchange of recording their screens + their faces and voice while they use our site. It shouldn't be too hard to use the camera to do eyetracking, either. If I wasn't building a public-facing website and had not done in-person usability tests, I wouldn't have thought of this.
