Transcript of Second presentation o.c.o. technology & paper prototyping
OPTIMISING CHILDREN’S OUTCOMES
(OCO)Technical Presentation
Erika Fisher, Camilla Mahon, Hannah Rogers & Gabriella Kavanagh
THE APPLICATION
Apple iPad Application
Aim of the application is to monitor and manage
classroom behaviour
Monitors
Students’ eye-contact with the blackboard
Noise levels of the classroom
Complies data into easy to read graphs
Allows teachers to examine class performance
throughout the day
Each child will have a profile
Data from the App can be emailed to parents
THE TECHNOLOGY
Axure and Adobe Illustrator
Axure
A wireframing, rapid prototyping and specification
software tool aimed at web and desktop
applications
Why we chose Axure
Previous knowledge using the system
Creates detailed, realistic prototypes
Acts out user requests (buttons, type, etc.)
Adobe Illustrator
A vector based graphics editor developed by Adobe
We will be using Illustrator to create graphics for
our app
Why we chose Adobe Illustrator
Creates good quality graphics
Strong knowledge with using the system
Less restricting than other programmes, such as
Photoshop
THE PSYCHOLOGICAL RESEARCH
Eye-Tracking
A study examined student’s attention in class and gaze and focus patterns
Results showed students’ focused more on the blackboard than the instructor [1]
Noise Levels
Studies have shown that high levels of ‘classroom acoustics’ can have an adverse effect on students’ academic performance [2]
Research illustrates that children’s performance at school including cognitive abilities such as memory and reading ability as well as motivation can be negatively affected by noise [3]
THE DESIGN PRINCIPLES
(INTERFACE DESIGN)
Nielsen’s Heuristics and Pressman’s Principles
How we plan to apply interface design rules to our prototype
Nielsen’s Heuristics
They are called "heuristics" because they are more in the nature of rules of thumb than specific usability guidelines [4]
Pressman’s Principles
An agile yet disciplined framework for building web applications [5]
NIELSEN’S HEURISTICS
(EXAMPLES)
Help users
recognize, diagnose
and recover from errors
Error messages should
be expressed in plain
language, precisely
indicate the
problem, and
constructively suggest
a solution
NIELSEN’S HEURISTICS
(EXAMPLES)
User control and
freedom
Users often choose
system functions by
mistake and will need
a clearly marked
"emergency exit" to
leave the unwanted
state without having to
go through an
extended dialogue
PRESSMAN’S PRINCIPLES
(EXAMPLES)
Navigability
The user should be
able to understand
how to move about the
WebApp without
having to search for
navigational links
THE USER GROUP & THE USABILITY TESTING
Primary school teachers
Paper Interface Testing
Participants completed tasks
Participants gave us feedback about our
concept, the design and the ease of usability
After each round of usability testing we received
feedback from participants and amended out
prototype accordingly
From this process we made significant
adjustments, such as changing graphing of
behaviour to present data in a clearer way
USER GROUP
Persona Example
Sarah Smith, 28 year old primary school teacher.
She is organised and always keeps on top of tasks.
Owns many computer gadgets so is computer
literate. Motivated by innovation and using a
modern and technical approach to learning, she
believes it’s the way forward and is excited to learn
more about Optimising Children’s Outcomes (OCO)
using a monitoring system.
PAPER USABILITY TESTING
Test Stage 1
Homescreen
Feedback
Change search bar to
class list (as nothing
under it – too much
white space)
Include profile picture
of child?
Changes
Convert to List
PAPER USABILITY TESTING
Test Stage 2
Homescreen
Feedback
Divide List to allow it to
look more obviously
like a button
Changes
Change list layout
Include button arrows
PAPER USABILITY TESTING
Additional Feedback
iPad not widely accessible, as opposed to a
smartphone
Changes
Switch from iPad app to iPhone app
