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.
