1. Creating User Interfaces Embedded computing. Make assignment Classwork: Start thinking about target, teams. Homework: Post proposal, team members.

2. Embedded computing Performs set tasks (aka pre-defined tasks) with computer totally encased in device Strict requirements for performance and usability – May be outside. May need to function in inclement weather.

3. Embedded computing Parking meters Tickets (e.g., Metro North) ATMs Cars – Interfaces we see, such as GPS, fuel levels, connection to phones for music, phone – Note: substantial computing goes on for fuel, steering, etc. More?

4. Embedded computing, cont. Point of Sale (replacement for cash registers) Medical equipment Factory equipment Devices making up "smart house" – Thermostats – Alarm systems – Safety monitors – More?

5. Characteristics Single use or small set of uses Small[er] screens Touch Limited resolution No or very limited learning required – But … my 2013 car came with 8 manuals Robust with respect to human error More?

6. Technologies Microprocessor Sensors Memory Network connections All need to meet specific performance requirements (e.g., power consumption, heat, durability). Hardware or software may be special purpose or not.

7. Special considerations Accessibility – Can everyone in target user group see (use) and reach interface? – Is there support for languages other than English? – ? Error prevention Error recovery

8. Assignment Identify single or pair of similar devices. – Comparisons are always good, but you probably won’t have the same subjects. – For example, parking lot kiosks in two different parking areas Define task. Approach strangers and/or recruit subjects. – BE CAREFUL and be polite. Consider offering candy! Document and prepare presentation.

9. Documentation & Presentation One-pager – Summary of project – Photographs of screens Presentation – Approach – Photos – Results – Analysis

10. Rationale for assignment Get ideas on effective interfaces. Practice observing and working with subjects. Improve presentation skills – Written and oral

11. Classwork Form teams and decide on general targets and approach. Homework: post proposal. Time next class for planning.
