Most existing user models for dyslexics merely consider cycle. Therefore, a system will be more effective if the user is dyslexia types and learning difficulties. There is a lack of more motivated. Especially for students with dyslexia, it is empirical research investigating motivational determinants and common for them to experience more learning difficulties that their impact on learning behaviour. affect their learning motivation. That’s why we need to employ In this research, we examine dyslexic learners’ use of techniques to enhance user motivation in the interaction assistive learning technology to identify their specific process. In this research, we will present a system architecture characteristics regarding motivations and barriers faced when for motivation-enhanced learning and the detailed process of using a mobile learning software so that the dyslexic users’ the construction of our motivation model using ontological motivational needs can be incorporated into user modelling to approach for students with dyslexia. The proposed framework better adapt assistive learning technology to their specific of the personalised learning system incorporates our motivation needs. Our eventual aim is to provide a personalised learning model and corresponding personalisation mechanism aiming to system for students with dyslexia based on our motivation improve learning motivation and performance of students with model to improve learning success. dyslexia.

Dyslexia is the most common specific motivation-based personalisation illustrated by certain key learning difficulties which can affect the way information is inference rules.

RELATED WORK personalisation of learning service rather than being “cured”. In addition to various learning difficulties such as those Assistive technology can help dyslexic learners to regarding reading, writing and speech, dyslexia can also bring overcome some of the difficulties that they face. There is now a wide range of different technologies available helping with many aspects of dyslexia with software and hardware that helps The data input for building user models can be from with reading, writing, mathematics and organization. These different sources. Razmerita et al has discussed two ways in technologies are becoming increasingly adaptive and more which user information can be gathered to identify and adapt to mobile. The research area is this paper is personalised learning the user, either using user supplied data or through system systems, which is also called intelligent tutoring systems collected data [15]. One example of this in practice is shown in providing automated adaptive guidance, compared with the Hatala and Wakkary’s Ec(h)o System [16], a museum other area, educational games as the other approach to installation that can adapt to the types of museum visitors based technology-enhanced learning according to Peeters [9], as on their interactions with the system. This allows the dyslexic adults may find learning games boring which can work differentiation between visitors who want detailed information well on dyslexic children [10]. Therefore, personalised learning versus busier visitors who just want an overview. A similar systems have wider target users. method uses hierarchical relationships to depict the user model. The personalisation process will often require an input of Kim and Chan [17] discussed a user interest hierarchy which data, a method of algorithmically processing the data and then looks at user attributes but places in a general to specific a final inference or decision that can be used by the system to hierarchy. The user’s behaviour on the web site can then be used tailor the experience, configuration, behaviour or output to the to populate the hierarchy and algorithm can be used to cluster user.

The filtering can with dyslexia helps separate out the needs of different types of be rule-based, content-based, collaborative or a combination of dyslexia. Dyslexia is firstly classified by Ingram [18] into three them [11]. Specifically, the rule-based approach requires that main categories being visuospatial difficulties, speech-sound pre-defined rules are used to customise data. This however can difficulties and correlating difficulties. The visuospatial be inflexible and difficult to update. The content-based difficulties refer to difficulties in distinguishing between letters, approach looks at text data but is not supported for multimedia. syllables and phrase orders, relying on shapes to identify the The collaborative approach uses interest detection of many letters. This may cause issues with identifying the letters and people but does not give satisfy results for new users or items. confuse the order of the letters. The speech-sound difficulties Often a hybrid approach combining all these approaches can refer more to difficulties in spoken language, the forming of give better results but it complicated and difficult to implement sentences and the separation of words into component syllabi. [11]. The correlating difficulties are more concerned with writing User modelling while beneficial for designing applications difficulties where they are not able to link letters to speech are often used for real-time personalisation and adaption of sounds [19]. Dyslexia is categorised into five types by Alsobhi services. User modelling approaches are mainly classified into et al corresponding to five difficulties experienced by students two categories: knowledge-based approaches and data driven with dyslexia: reading, writing, speaking, mathematics and approaches. Data driven user modelling makes use of memory [19]. Although these types are defined separately, they techniques in machine learning and data mining to examine the often occur in combination with an individual possibly having relationships among various sensor data and situations 2 or 3 of these types [19]. surrounding the user, whereas knowledge driven user Alsobhi et al [20] have attempted to linking dyslexia types modelling primarily represents user models via logic rules and and symptoms to the available assistive technologies by applies reasoning engines to eventually infer personalised summarizing the different existing assistive technologies and service from the environment [12].
