“…This record waived the presence of an evaluator during intervention or diagnostic procedures, allowing the subjects with Down syndrome to act more spontaneously 46 . According to the literature [43][44][45][51][52][53][54][55][56][57][58][59] , children act spontaneously when playing as well as using all the knowledge already acquired. Additionally, the reports and graphics that can be generated by the environment from the recorded data allow us to conclude whether the subject with Down syndrome has actually established a routine.…”

A child with Down syndrome, like any other child, may benefit from interacting with memory stimuli, but needs additional support and help. The use of special teaching methods, which add playfulness and use of the computer, can enhance the memory processes of these children. In this work, we present the virtual environment "Nossa Vida (Our Life)", which was developed to assist children with Down syndrome to memorize action sequences of their daily routine. A daily routine memorization test (DRMT), consisting of a weekly reminder of typical daily routines completed by the children and parents, was performed before (pre-test) and after (post-test) the intervention. The work involved a multidisciplinary team and assessed the effectiveness of the test performed by 30 children with Down syndrome from APAE, a special education school for children with intellectual disabilities in São Paulo, Brazil. The children were separated into two groups (Experimental -GE and Control -GC) with homogeneity and normality of the data. Two hypotheses were tested in this study: H0 and H1, where: H0 = There is no statistical difference between memorizing daily tasks between individuals with Down syndrome who used our ludic virtual environment and those who used the conventional memory method.H1 = There is a difference between the group of subjects with Down Syndrome who used our virtual game environment and the group that did not use it in relation to memorizing the daily task. This produces t = -14.98 and p <0.0001, with H1 being accepted. The results showed that the EG presented significance in relation to the CG and the evolution mean of the children in the EG was 81.82% higher. According to experts (psychologist and pedagogue) from APAE and parents, the playful activities implemented in this virtual environment have been of great interest to children, who had fun, tested hypotheses and questioned them about the sequences of actions performed in their routine daily.

“…Despite the increasing number of scientific studies regarding AAC app development, few studies focused on usability (Quintela et al, 2013). As a result, the anticipated benefits may not be realized for numerous individuals, not because they cannot benefit from AAC, but rather because the AAC apps are either difficult or impossible to use by individuals with motor impairments (Scardovelli and Frère, 2015). Therefore, it is essential that developers use new technology to create apps that are more accessible to the impaired in order to minimize their limitations, contributing to their independence, quality of life, and participation in society (Loja et al, 2015).…”

Introduction: Communication is a fundamental element for the development of human beings, promoting their coexistence in society. However, changes in muscle tone, associated with cerebral palsy (CP), among other conditions, cause phono-articulatory dysfunctions hindering speech capabilities. Although there are resources for augmentative and alternative communication (AAC), most of them do not completely satisfy the needs of individuals with motor impairment. Therefore, this study proposes a tool based on mobile technology for AAC, which can be adapted to the characteristics of the motor limitations of CP users. Methods: Mobile system development was conducted employing user-centered design and development methods. Functions were developed allowing the communication of phrases through pictographic resources and a mechanism of speech synthesis, that can be customized according to specific communication needs. To validate this system, 20 CP volunteers with speech difficulties and motor impairment were recruited from two institutions in the State of São Paulo, Brazil. They operated the system following a pre-defined test protocol, and they answered a system usability scale (SUS) questionnaire, to rate the ease of learning, memorization, efficiency, occurrence of runtime errors, and the level of user satisfaction. Results: The results showed a score of 85.85 ± 2.28 above the average SUS scale, for each one of the quality components assessed by the volunteers. Conclusion: The developed software is user-friendly, representing a new option for AAC, and is customized according to the communication needs of people with speech disorder and motor impairment.

“…Also, Boschi and Frère (2013), have developed a system composed of a virtual environment associated with a peripheral device to evaluate the Range of Motion (ROM) and the grip and pinch strength movement. Other authors have also developed computer games, which were connected to a modified device, so it could offer learning and leisure options for people with severe upper limbs motor limitations (Scardovelli and Frère, 2015). Some studies have also reported the creation of a dynamometer that was easy to manipulate and portable to be used in rehabilitation clinics and hospitals, especially by assisting the clinical evaluation process (Canuto et al, 2016;Lin et al, 2012;Schrama et al, 2014).…”

Introduction: Grip and pinch movements are important to perform daily activities and to manipulate objects. In this paper we describe the development and evaluation of a peripheral device to quantify cylindrical grip, pulp-to-pulp pinch, pulp-to-side pinch strength and range of motion of children. Methods: Three objects were selected: a door handle, a switch, and a key, which were instrumented with force sensing resistors to analyse the strength. Potentiometers were used to verify the range of motion and micro switches to assure the correct position of the fingers during the movement execution. Thirty volunteers (8.77 ± 1.28), both male and female, were selected to test the peripheral device functionality. Results: The results determined the minimum necessary strength values for the object activation and maximum displacement, in which the values are 2.5N, 40°; 2.7N, 55°; and 2.8N, 100%, for door handle object, key object, and switch object, respectively. In the functionally tests, volunteers have shown a superior strength for activating each object and 73.33% of them have completed the range movement in the key object, 86.67% in the switch object, and 93.33% in the door handle object. Conclusion: The developed peripheral device enabled the measurement of range and static and dynamic strength of grip and pinch movements of children.
