We considered several design solutions for our own procrastination challenges, even one with its own digital currency. Ultimately, we found the most helpful solution would neither reward us for being on-task, nor punish us for being distracted: it would merely eliminate the initial opportunity for us to become distracted. Walden enables users to restrict the usage of their computer to a single app for a predesignated period of time. By removing the ability to engage with all other applications, Walden allows users to focus, stay on-task, and achieve Thoreau-like serenity.
