Outline Introduction to Usability Science Project requirements Design Future work Questions
3
Introduction What is Usability Science?
4
The Project A system to simulate control panels and record test data
5
Requirements Simulate the layout of a control panel repositionable Programmable connect inputs to desired outputs Log events
6
Additional Requirements Repositionable I/O devices (widgets) Ease of physical setup Easy to update/modify Easy to create new widgets
7
Additional Desired Features (“wish list”) Easy to program (with little computer experience) Aesthetics
8
Design I/O Widgets: Simple input or output devices (switches, lights, etc.) Controller Event Logger Controller- widget communication via ethernet
9
Widget
10
Controller State Machine User program defines state machine Controller loop: Wait for an input signal Change outputs based on input and state Change state Send input/output/state change data to event logger
11
Event Logger Receives/records messages from controller: input received output changed new state add time stamp
12
TINI Networked Microcontroller controls each widget runs Java built-in Ethernet capability
13
Results Working with two TINI Networked Microcontrollers Fully implemented widget
14
Future Work Implement full controller and event logger Create more widgets!
