Because tasks are so important to our daily lives, they have been studied extensively. Previous studies have shown findings surrounding these concepts:

• Time estimation : Previous studies have shown that estimating time has revealed many cognitive biases that impact how one accurately estimated the duration of a task.
• Task assistance: Though there are many applications nowadays, they still requires that the systems have a certain knowledge of which tasks are microtasks.
• Productivity: This study differs from microproductivity research. Instead of focusing on larger productivity, like a large project, this study focuses on short, non-committal tasks that can be carried out throughout a normal day. These tasks do not need to be part of a larger task, and are usually user-generated.
• Crowdsourcing: Crowdworkers are provided with short, context-free tasks that they are able to complete at any time, but usually with a certain duration goal. While this is important, this study focuses on the average person’s daily tasks, not the goals of crowdworkers.
• Tasks in search and retrieval: People use search systems to finish a range of tasks and this duration has been used to program search algorithms. Evidence of this task completion is observed in previous search log data. Search can play a role in the completion of microtasks after they’ve been identified, helping find the required resources (digital or physical).
