Vanita, Robin, Jeannette, & Chris
*Production Paper Summary
*Background
*Social modeling for children with
Asperger’s
*Direction taken from usability testing
*Tutorials to support first-time users
*Clarify button names
*Design Decisions
*Animation
*Practical considerations
*Functional considerations
*Attract attention (Lowe, 2004)
*Engage learners (Lowe)
*Sustain motivation (Lowe)
*Reduction of extraneous cognitive load (Mayer et al.,
2005)
*Design Decisions
*Animation – Research is inconclusive
*Ayres et al. (2005; 2007) identify why
animation may not be effective:
* Information is transitory
* Animations are a series of successive elements
*To offset these characteristics:
* ‘tracing’ – leaving information on the screen
* Build in user-control (Ayres et al., 2005)
*Voice and Text
*Objective of using voice–overs/ sound and text:
*To enhance user experience
*To engage and catch the user’s attention
*Rationale:
* “In contrast to print and audio comparisons, which generally reveal no advantage for dual over single presentations, studies show that adding pictures to print or audio generally increases learning” (Nugent, 1992)
*A dual modality presentation improves user comprehension and retention.
*“Flexibility is extremely important to system use since different users may require different degrees of support” (Sipior and Garrity, 1992)
*A mix of audio and visual components improves attributes such as perception, attention, comprehension, and retention.
*Research also revealed some Disadvantages
*“a special consideration for video (and spoken audio) is that any narration may lead to difficulty for international users as well as for users with a hearing disability” (Nielsen, 1995)
*Decision made:
*a combination of voice and
*use of simple text along with graphics and icons.
Text and Voice
Voice
Text
*Colour and Graphics
*Facilitate learning rather than distract
* Figure familiarity and consistency
* Clear, recognizable, transferable, simple shapes,
symmetry or balance of positioning
* Coordinated color palette and background
contrast
* Text without button surround:
simplified, less cluttered
*Segment Length
*Episodic nature of memory – Mayes & Roberts (2001) – visual information most salient
*Optimal web video episode length – Nielsen (2005) - keep it short, less than one minute
*Google Sketchup and Adobe tutorials – one to eight minute lengths
*Czerwinski & Horvitz (2002) – let a previous task item fade from memory before introducing a new one
*An issue of length or amount of information required to perform a task?
*Assessment of Learning
*Usability testing
* Parallel design: test multiple design prototypes
* Dynamic animated – graphics, voice, text
* Still images with text
* Test efficacy of learning with Virti-Cue mock-up
* 3-5 Users
* Test with/without both designs
* Open-ended questionnaire plus compare/contrast
* Observation of specified task performances
* Iterative design
* Ease and efficiency of use
* Few errors, pleasant to use
* Achievement of learning goal
*Static Graphic/Text
*Animations
*Trial 1 – Stop Action Animation
*Trial 2 – Animating ‘Jings’
*Trial 3 … Word, Jing, PinPoint, Camtasia - final?
*Animating ‘Jings’
