That wouldn't be the only party trick. The watch would recognize wrist gestures beyond the simple screen activation you find in Samsung's Gear line, for a start. It would also have a Moto 360-style circular display with both an optimized touchscreen interface and a rotating ring for tasks like scrolling. It's an ambitious, do-it-all design, and it won't be surprising if Samsung only uses some of the technology -- if it's used at all. When Samsung is already big on gesture control and plans to support Android Wear, though, there's a real chance that future smartwatches will let you do much more than poke at buttons and issue simple voice commands.
