Google Glass and Microsoft Hololens products augment reality by bringing reminders for events and tasks up right in front of the user's eyes. They also map routes, calculate the amount of time it will take to travel to events, and schedule alerts to tell users when to leave, how to get there, and what to bring. On a less complicated level, mobile applications for smartphones that specialize in scheduling, task planning, note-taking, and project management are an enormous market for personal devices and corporate ones.
