Contributions
• New	indicators	for	predicting	dyslexia while	playing	a	Game	
called	DysMusic.
• Usability	improvements to	the	first	version	of	the	game.

Motivation
4
Motivation - Dyslexia
• What	is	dyslexia?
• How	many	are	affected?
5
@Rauschii | www.mariarauschenberger.com
Motivation - Dyslexia
• Who	is	affected?
• How	does	dyslexia	affect	
your	life?

Examples of Digital Detection: Pre-Readers
• DYSL-X	/	DIESEL-X	(Geurts et al. 2015, Audenaeren 2013)
• Bielefelder Screening(Steinbrink and Lachmann 2014)
• AGTB	5–12	(Steinbrink and Lachmann 2014)

Dyslexia	is	normally	detected	using	linguistic	elements.
That	can	only	be	possible	when	children	have	already	developed	
reading	skills.	
Is	it	possible	to	predict	that	a	child	may	have	dyslexia	before	
s/he	develops	reading	skills?

Why Musical Elements?
Indicators
• Short-term	memory	difficulties	
• Phonological	memory	/	awareness
• Working	memory
⇒ For	Readers	and	Pre-Readers
DysMusic

Goals
• Finding	dyslexia	pre-readers	indicators	related	to	music
• Integration	of	successful	items	in	a	game	to	predict and	
intervene dyslexia

“What do you hear?”
Content Design
Tasks Related to Indicators
• Finding	the	same	sound	
• Distinguishing	between	sounds
• Short	time	interval	perception,	e.g.	
short-time	intervals

Example
• 4	tasks,	each	with	2	subtasks
• One	subtask	with	4	cards,								
the	other	with	6	cards	
• 4	different	acoustic	parameters
• Frequency	
• Length
• Rise	Time
• Rhythm

User Study & Results
Usability Study
• 5	users	study	
• five	children	(user)	and	five	parents
• within-subject	design,	counter-balanced

Results
• Interaction:
• After	first	task,	they	go	faster,	independent	of	the	musical	
element
• Musical	Elements
• Listen	and	concentrate	carefully
• Difficult	level	difference	perception
• Functionality
• Video	player	(	HTML	5:	video-tag	to	YouTube:	Iframe-tag)

Conclusions & Future Work
21
• Language	independent
• Could	be	for	pre-readers
• Visual	Elements
• Large-scale	study	in	
English,	German	&	Spanish
