Playing error-based exercises presented in a computer game
was found to significantly improve the spelling skills of chil-
dren with dyslexia in Spanish. Since there are no similar
error-based exercises for German, we adapted the method
to German and created 2,500 new word exercises. Since
dyslexia manifestations are language dependent, the replica-

1. INTRODUCTION
Motivation. In Germany, between 5 and 12% of stu-
dents have dyslexia, a neurological learning disability which
impairs a person’s ability to read and write. Also in Ger-
many, only 25% of the poor spellers achieve average spelling
performance during primary school [7]. In a longitudinal
study Esser et al. [1], showed that children who were di-
agnosed with dyslexia at the age of 8 achieved lower school
performance and higher rates of unemployment than a con-
trol group (measured afterwards at the age of 25). Later,
Schulte-K¨
orne et al. [8] showed that it takes longer for a
child with dyslexia to achieve school grades that are com-
parable to the others, even if they have an above-average
socio-economic status and are given effective treatment.

Background Research. To support the spelling of chil-
dren with dyslexia in Spanish, Rello et al. [6] designed a
method to create exercises based on the linguistic analysis
of the errors made by children with dyslexia. It is called
an error-based method because it uses written errors as a
starting point since (1) dyslexic writing errors are related to
the types of difficulties that they have [10]; and (2) readers
with dyslexia cannot consciously see errors in words [3]. The
exercises were integrated in an iOS game, Dyseggxia (Pirule-
tras) [5], which was subsequently evaluated in a school. Over
eight weeks, the authors carried out a within-subject exper-
iment with 48 children from 6 to 11 years old. The children
who played DysEggxia for four weeks in a row had signifi-
cantly fewer writing errors in the tests than those playing
Word Search –the control condition– for the same time [6].
Solution. In this demo we present the German extension
of that tool and explain the adaptation of the method to
create word exercises for children with dyslexia. It is worth
noting that despite the universal neuro-cognitive basis of
dyslexia, dyslexia manifestations are variable depending on
the degree of consistency and regularity of the language or-
thography. German has a semi opaque language, that is, the
relationships between letters and sounds are not as regular
as in other transparent languages as Spanish [9]. In addi-
tion, it also has more complex syllabic structure [9]. Hence,
the adaptation of the method from Spanish was not straight-
forward, raising a number of challenges. To the best of our
knowledge, this is the first approach to create German error-
based exercises for people with dyslexia.
2. RELATED WORK
Specifically for German we found Lernserver1, a tool to
diagnose and provide support exercises. The tool was evalu-
ated in 2008 with the Landesinstitut f¨
ur Schule, where 78.2%
of the students (N = 3,798) improved their writing by using
this tool [2]. Klex 11 2 is a tool to practice vocabulary in
German adapted to a certain school degree. The exercises
of Klex are not error-based since only the correct words are
presented. We could not find literature on how Klex was de-
veloped and how the exercises have been created. Similarly,
CESAR schreiben 2.0 3 is a strategy and educational game,
which includes listening, spelling and vocabulary exercises.

To the best of our knowledge, there is no tool to support the
spelling performance of children with dyslexia for German
based on written errors that they make.
3. GERMAN ADAPTATIONS
Below, we explain the steps to replicate the method and
describe the specificities added for German.
Texts Collection. The first step was the collection of
dyslexic errors. We collected 47 texts (homework exercises,
dictations and school essays) written by students with ages
ranging from 8 to 17 years old. A total of 32 texts were
written by children who have been diagnosed with dyslexia.
The remaining 15 texts correspond to students with a high
spelling error rate that were identified by their teachers.
The students attended either primary school, comprehen-
sive school (Gesamtschule), high school (Gymnasium) or a
special school (F¨
orderschule).
Error Annotation. We manually extracted the errors
and annotated them with phonetic and visual features [4].
These features were specific to the German writing system
and phonetics. For instance, German has letters and sym-
bols, that do not exist in Spanish or English, e.i. ß, ¨e, oa, ¨ ¨
and ¨
u. In addition to that, the handwriting systems broadly
used in schools (Lateinische Ausgangsschrift) presents dif-
ferent letter forms, so the visual analysis of the letters was
language specific.
Linguistic Analysis. Third, we analysed the errors lin-
guistically. These analyses had to be specifically performed
for German specific syllabic structure and semi opaque or-
thography, for instance, the group of letter <sch> are pro-
nounced as only on phone [S]. This resulted in different error
categories as well as different linguistic criteria.
Creating the Exercises. We created exercises taking
into account the previous linguistic analyses. As a result we
had 8 types of exercise: (a) add a letter; (b) remove a letter,
(c) change a letter (see Figure 1, right), (d) choose the cor-
rect word ending, (e) cut into words (see Figure 1, left), (f)
order the letters or syllables, (g) capital letter, and (h) wrong
capital letter. The last two exercises are specific to German
where nouns are always written with capital letters, and
missing capitalization is a frequent misspelling. Also, cut
into words exercises included words and morphemes specific
to German such as the trennbare verben, that is, verbs is
that are preceded by prefixes.
Difficulty Levels: Thre are five difficulty levels: Initial,
Easy, Medium, Hard, and Expert. Higher levels included
less frequent words, longer words, and words with a more
complex morphology. The criteria to define the levels were
adapted to German. For instance, all levels presented longer
words and morphology played a stronger role because Ger-
man has a more complex morphology and longer words.
4. CONCLUSIONS AND FUTURE WORK
Using the adaptation of the method described above, we
manually created 2,500 German exercises. The exercises
were integrated into the iOS app Dyseggxia (Piruletras).
4
For future work we plan to carry out a longitudinal eval-
uation of this tool in a German school. Moreover, we will
be able to compare how error-based games are more or less
effective for certain types of languages.

Article
The choice of appropriate interaction style for children's application has been a divisive subject of debate. For example, drag-and-drop is often said to perform worse than point-and-click in educational applications-and vice versa. In this article, we argue for the need to choose the interaction style in context, considering a range of factors. We compare drag-and-drop, point-and-touch, and simple touch for selecting letters to form words in a spelling line as part of an educational spelling game. We evaluate the perceived workload, user experience, preference, and writing times of twenty-five children (8-11 years), eight of whom were dyslexic. We found that touch received better ratings and was ranked highest most often on all subscales compared to drag-and-drop and point-and-touch. Children needed less time using touch and 68% chose it as their favorite interaction style. We also found small advantages for drag-and-drop over point-and-touch, which runs counter to some recent recommendations. This becomes particularly clear when using ranking responses, which support a particularly fine-grained picture.

In this paper we present a language resource for German, composed of a list of 1,021 unique errors extracted from a collection of texts written by people with dyslexia. The errors were annotated with a set of linguistic characteristics as well as visual and phonetic features. We present the compilation and the annotation criteria for the different types of dyslexic errors. This language resource has many potential uses since errors written by people with dyslexia reflect their difficulties. For instance, it has already been used to design language exercises to treat dyslexia in German. To the best of our knowledge, this is first resource of this kind in German.

The aim of this research is to show that a playful approach combined with music can detect children with dyslexia. Early detection will prevent children from suffering in school until they are detected due to bad grades. Our envisioned web application will contribute to 10% of the population by giving them a chance to succeed in life and find their skills to impress the world.
Chapter
Dyslexia is a learning disability characterized by difficulty in reading. Individuals suffering from this disease have normal intelligence and vision. Dyslexic patients face problems in creating links between alphabets shown to them and their phoenix. This disease affects the portion of the brain that functions to process alphabets and words. Interventions and therapies can help the patients to improve their capability to learn. A plethora of game-based interventions (GBIs) for a diverse set of learning disorders has emerged over the last decade. However, studies comprehensively reviewing GBIs for dyslexic patients, are still nonexistent. This systematic literature review (SLR) fills this research gap by providing a comprehensive overview of the use of game elements and game-based intervention methods in enhancing the learning capabilities of dyslexic patients. The methodological foundations of this SLR have been extracted from Kitchenham’s guidelines for systematic reviews. Relevant studies have been extracted from six electronic databases and the study selection process complies with the structured PRISMA guidelines. Out of an initial set of 950 studies, 42 studies were selected through a systematic and unbiased selection procedure followed by the data extraction, analysis, and reporting of findings. The results of this SLR provide evidence of the effectiveness of game elements and GBIs for patients suffering from dyslexia. The findings signify that word exercise-based games represent the predominant category of games followed by action-based video games. In contrast, other categories of the games, i.e., puzzle-based, strategy games, are rather scarce in this domain. None of the selected studies has used self-determination theory (SDT) as the basis of their game design. In addition, most of the selected studies fail to provide comprehensive coverage of the essential gaming elements. Future research efforts must be directed towards these shortcomings to improve the current state of the research.
Thesis
Full-text available
Children with dyslexia have difficulties learning how to read and write. They are often diagnosed after they fail in school, even though dyslexia is not related to general intelligence. In this thesis, we present an approach for earlier screening of dyslexia using a language-independent game in combination with machine learning models trained with the interaction data. By earlier, we mean before children learn how to read and write. To reach this goal, we designed the game content with knowl- edge of the analysis of word errors from people with dyslexia in different languages and the parameters reported to be related to dyslexia, such as auditory and visual perception. With our two de- signed games (MusVis and DGames), we collected data sets (313 and 137 participants) in different languages (mainly Spanish and German) and evaluated them with machine learning classifiers. For MusVis we mainly use content that refers to one single acoustic or visual indicator, while DGames content refers to generic content related to various indicators. Our method provides an accuracy of 0.74 for German and 0.69 for Spanish and F1-scores of 0.75 for German and 0.75 for Spanish in MusVis when Random Forest and Extra Trees are used. DGames was mainly evaluated with German and reached a peak accuracy of 0.67 and a peak F1-score of 0.74. Our results open the possibility of low-cost and early screening of dyslexia through the Web.
Chapter
Nowadays, being excluded from the web is a huge disadvantage. People with dyslexia have, despite their general intelligence, difficulties for reading and writing through their whole life. Therefore, web technologies can help people with dyslexia to improve their reading and writing experience on the web. This chapter introduces the main technologies and many examples of tools that support a person with dyslexia in processing information on the web, either in assistive applications for reading and writing as well as using web applications/games for dyslexia screening and intervention.
Conference Paper
With a considerable population being reported with learning disabilities, several studies stress the relationship between these disabilities and physical activity. Language and learning therapy aims to improve cognitive skills. However, therapy is time consuming and based on the expertise of the therapist's clinical eye. Considering this, we conducted a 10-week study of an indirect sensing surface to support Movement-Based Learning therapy. Our findings indicate positive outcomes in use, engagement, motor skills, and traditional therapy. These findings offer design implications to support Movement-Based Learning Therapy to support children with language and learning disabilities.

Micro Electro Mechanical Systems (MEMS) are movable structures fabricated on the surface of silicon chips by selectively depositing and etching away materials and silicon. Such movement allows the measurement of a wide range of parameters. In the recent years, the integration of MEMS devices and electronics on the same chip i.e. CMOS-MEMS integration, has allowed the improvement of sensors’ performance and fabrication costs, extending their integration in all types of devices. In the Advanced Hardware Architectures research group at the UPC, we are currently conducting research on system-on- chip CMOS-MEMS magnetic field and pressure sensors. Contrary to pressure sensors using other technologies, resonant pressure sensors allow direct coupling to digital electronics without requiring analog to digital converters (ADCs). This feature enhances their resolution and reliability by providing more immunity to noise and interference. Recently, monolithically integrated CMOS-MEMS resonant pressure sensors have been extensively used in atmospheric pressure monitoring and altitude sensing due to their low cost, small size and high reliability. Presently, the pressure sensors integrated in the smartphones and wearable devices suffer from poor sensitivity. The primary purpose of our study is to develop an optimized CMOS-MEMS resonant pressure sensor with enhanced sensitivity at atmospheric pressure which can be utilized in a vertical GPS enhancement system. Magnetic field sensors are key in the development of electronic compasses integrated in smartphones and other devices. Currently, magnetic sensors used in smartphones do not use MEMS technology but sensors that require materials incompatible with the fabrication of CMOS electronics. Our objective is to improve the performance of MEMS based electronic compasses by using Lorentz force based MEMS magnetic sensors. Such sensors, are compatible with CMOS process and could substitute actual sensors by reducing fabrication cost.

We introduce a language resource for Spanish, DysList, composed of a list of unique errors extracted from a collection of texts written by people with dyslexia. Each of the errors was annotated with a set of characteristics as well as visual and phonetic features. To the best of our knowledge this is the largest resource of this kind, especially given the difficulty of finding texts written by people with dyslexia.

Several previous studies have suggested that basic decoding skills may develop less effectively in English than in some other European orthographies. The origins of this effect in the early (foundation) phase of reading acquisition are investigated through assessments of letter knowledge, familiar word reading, and simple nonword reading in English and 12 other orthographies. The results confirm that children from a majority of European countries become accurate and fluent in foundation level reading before the end of the first school year. There are some exceptions, notably in French, Portuguese, Danish, and, particularly, in English. The effects appear not to be attributable to differences in age of starting or letter knowledge. It is argued that fundamental linguistic differences in syllabic complexity and orthographic depth are responsible. Syllabic complexity selectively affects decoding, whereas orthographic depth affects both word reading and nonword reading. The rate of development in English is more than twice as slow as in the shallow orthographies. It is hypothesized that the deeper orthographies induce the implementation of a dual (logographic + alphabetic) foundation which takes more than twice as long to establish as the single foundation required for the learning of a shallow orthography.
Article
In this paper we present a method which aims to improve the spelling of children with dyslexia through playful and targeted exercises. In contrast to previous approaches, our method does not use correct words or positive examples to follow, but presents the child a misspelled word as an exercise to solve. We created these training exercises on the basis of the linguistic knowledge extracted from the errors found in texts written by children with dyslexia. To test the effectiveness of this method in Spanish, we integrated the exercises in a game for iPad, DysEggxia (Piruletras in Spanish), and carried out a within-subject experiment. During eight weeks, 48 children played either DysEggxia or Word Search, which is another word game. We conducted tests and questionnaires at the beginning of the study, after four weeks when the games were switched, and at the end of the study. The children who played DysEggxia for four weeks in a row had significantly less writing errors in the tests that after playing Word Search for the same time. This provides evidence that error-based exercises presented in a tablet help children with dyslexia improve their spelling skills.

We present Dyseggxia, a game application with word exercises for children with dyslexia. We design the content of the game combining linguistic and pedagogical criteria as well as corpus analysis. The main contributions are (i) designing exercises by using the analysis of errors written by people with dyslexia and (i) presenting Spanish reinforcement exercises in the form of a computer game. The game is available for free on iOS and Android.
Article
The Mannheim ACCA study was designed to provide data on the etiology and course of mental disorders from childhood to adulthood. The objective of this study was to determine the long-term prospects for children with a specific reading and spelling disability concerning school performance, professional life, psychopathology, and self-perception. 31 8-yr-old dyslexics were compared with 45 children with other specific developmental disorders and a control group of 231 subjects. Children with specific developmental disorders showed a worse school performance than the control group. Compared with the control group, the dyslexics showed more psychopathological symptoms and a higher rate of unemployment. It is concluded that the presence of dyslexia at the age of 8 yrs has an unfavorable prognosis regarding school performance, professional life, and mental development. However, no effect on the self-perception of dyslexics was seen. (PsycINFO Database Record (c) 2012 APA, all rights reserved)

Die Rechtschreibleistung wurde mit dem Mannheimer Rechtschreibtest (MRT), die Psychische Befindlichkeit mit der Symptom-Checkliste von Derogatis (SCL-90), der Berufserfolg mit der «Magnitude-Prestigeskala» nach Wegener, die Intelligenz mit dem Culture Fair Intelligenztest (CFT 20) und die subjektive Beurteilung mit einem selbst entwickelten Fragebogen erfasst. Ergebnisse: Im Mittel hat sich die Stichprobe um eine halbe Standardabweichung in der Rechtschreibleistung verbessert. Das...
Article
Essays written by a group of 16 adult student dyslexics and 16 of their peers, matched for age, gender, and subject area, were compared on a number of dimensions. Analysis of the scripts revealed that the dyslexics wrote more slowly and produced shorter essays. The groups did not differ in sentence length or in the location of sentence boundaries. Dyslexics used more monosyllabic words and fewer polysyllabic words. Their spelling error rate was much greater than that of the controls, both overall and in most error categories, and their misspellings provided substantial evidence of a phonemic transcription strategy. Analysis of errors attributable to phonological impairment, spelling knowledge, and lexical misretrievals revealed all these to be more frequent in the dyslexics, but only in the case of phonological impairment did dyslexics produce proportionately more errors, suggesting a specific problem. These data are consistent with previous research suggesting a continuing phonological deficit in adult dyslexics.
