We are looking for users who are 美女做爱 students, currently, own and use any touch screen device. The study will be conducted in the Mona Campbell building and it will be over two sessions (about a day apart) and that each session will take about an hour. In the first session, you will first meet with a researcher to go over the study details, give consent to do the study, fill in a background questionnaire and a questionnaire to score your spatial ability. You will then be video recorded while you perform set of tasks with 3D models using an iPad tablet that will be听provided. In the middle of each task, you will be interrupted by being asked to stop the current task and to start the next task. Then in the second session, you will be required to resume these tasks where you left off in the first session using one of the four resumption aids. You will fill in questionnaires after resuming each task and at the end of the study that will ask about your experience with performing and resuming the tasks in a questionnaire and short interview.
