There’s an issue inherent with the idea of a smartphone with apps: it constantly needs to be fiddled with in order to access the appropriate app at the right time. DOT tries to alleviate that problem.
DOT is a small, LED-equipped device that acts as a beacon. With it, users can use it to better contextualize an environment and program a smartphone or tablet to adjust accordingly. For instance, should someone be reading a book on a tablet, sitting down on the couch will prompt the nearby DOT to launch the app with book being read to the page they left off.
