“Tasks are the real-world activities people think of when planning, conducting, or recalling their day. That can mean things like brushing their teeth, preparing breakfast, reading a newspaper, taking a child to school, responding to e-mail messages, making a sales call, attending a lecture or a business meeting, having lunch with a colleague from work, helping a child with homework, coaching a soccer team, and watching a TV program. Some tasks are mundane, some complex.”
