Task Analysis and Intuition Factors in Human-computer Interaction
2 likes561 views
Task analysis is a critical component of user experience design, focusing on how tasks are accomplished and utilized in research to improve software design. It encompasses both quantitative and qualitative measures, while considering intuition factors from both users and software creators. The process includes user testing, observation, and documentation to enhance the overall user interface and ensure successful task completion.
Task Analysis and Intuition Factors in Human-computer Interaction
- 1. Task Analysis and Intuition Factors in Human-computer Interaction 26 September 2017 Champaign, Illinois, USA
- 2. Task Analysis Basis - Human Factors and Psychology - Element of a UX Practice for User Testing - Used to conduct research or test against hypotheses
- 3. What is Task Analysis The observation (understanding) of how a particular task (any task) is accomplished.
- 4. Task Analysis in User Research - The practice of User Experience Design involves a variety of research and testing procedures, User Research - Task Analysis is a procedure used within the User Research and Testing process to accomplish the following: - Observe controlled variable set - User accomplishes a task (e.g., saving a file) - Testing existing design hypothesis - User understands X when accomplishing a task, so X must be present (e.g., using a floppy disk icon to indicate cloud sync)
- 5. User Research - Task Analysis is used in User Research to find quantitative and qualitative measures for a particular software design - Testing: How does the user perform the task?
- 6. Intuition Factors (Task Analysis Test User*) - Personal Instinct - What seems right to me as a user - Experience Driven - What has been successful in the past - Learned Usability - This procedure has worked for me before - Perceived Usability - How do I think the software creator wants me to accomplish this task *User is test subject
- 7. Intuition Factors are a two-way street - Software creators utilize intuition factors to get in the mind of the user - Users utilize intuition factors to get in the mind of the creator
- 8. Intuition Factors (Software Creator) - Personal Instinct - What seems right to me as a designer - Experience Driven - What has been successful in the past - Learned Usability - What has become a standard within the software user base - Perceived Usability - What do I think the user will do in this scenario
- 9. Great Design is based on data, partially User interface design is a combination of data collected from user testing/research and intuition One part data, one part intuition
- 10. Data is more than Task Analysis - User Research Results - Task Analysis - A/B Testing - Heatmaps - Eytracking - User Stories And more...
- 11. Task Analysis in practice - Part of the User Testing process: - Controlled environment for recording - Set a clearly defined task - Observe user closely - Ask user to speak their thoughts audibly - Discuss the session afterwards
- 12. The Analysis (the deliverable) - Create a report - Often delivered in the format of an email or .PDF - May include video recording or screencast - Include all aspects of the test - Include details of the subject - Solve for “Was the task successfully completed”
- 13. The Analysis (the deliverable) - Reports should include: - Success or failure - Duration - Thought process - Final user flow - Environment - Operating System - Hardware - Physical location - Complexity - Previous training - Instruction - Outside factors - Unknown unknowns - Other factors - Known unknowns
- 14. Task Analysis and Prototyping - Prototyping is a great way to segment task analysis - Remote (online) user testing with prototypes often require aspects of Task Analysis - Understand that intuition factors may interfere with task analysis and user testing subject bias
- 15. Closing - The User Experience Design process involves User Research and Testing - Task Analysis falls under User Research and Testing - Analyze task with the two-way intuition factors in mind - Task Analysis can help develop and refine the User Experience Design process
