The first one is UFocus. Devices made by Nokia and LG (and soon to be Samsung) have a way to let you change the point of focus after the pic is taken, Lytro-style. With it, you can change depth of field and add bokeh, but there's a catch: You have to be in a separate mode just to make it do what you want. This is typically because the camera needs to take several pictures over the course of five seconds to achieve the desired effect. When your child is having a cute moment, you rarely have time to figure out the best mode to use for the best picture; you have a split second to pull your camera out, point it and snap the shot before it's too late. HTC's Duo Camera, however, eliminates the need for these separate modes because it takes just one image and uses the image's depth information to determine which part of the photo to keep in focus.
