Creating User Interfaces
Embedded computing.Make assignment
Classwork: Start thinking about target, teams.Homework: Post proposal, team members.
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.
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?
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?
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?
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.
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
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.
Documentation & Presentation
• One-pager– Summary of project– Photographs of screens
• Presentation– Approach– Photos– Results– Analysis
Rationale for assignment
• Get ideas on effective interfaces.• Practice observing and working with subjects.• Improve presentation skills– Written and oral
Classwork
• Form teams and decide on general targets and approach.
• Homework: post proposal.• Time next class for planning.
