1.1 About Down Syndrome
Down Syndrome Individuals are the part of every society born with multiple challenges and on other hand they are challenge for the family where they born. They are supposed to be a social and economic burden on family and society. Down syndrome is caused by trisomy on chromosome-21 with a prevalence level of approximately 1 in every 800 births (Jamshidnezhad et al., 2021). Down syndrome occurs due to an extra copy of 21st chromosome also called trisomy-21. Individuals with DS may have substantial intelligence impairments and normally possess a level of Intelligent Quotient (IQ) ranging from 30 to 70. In addition to cognitive skills that are mostly decreased in these individuals include expressive language, memory, and fine motor skills. In cognitive ability, these individuals also have significant limitations in adaptive behaviour (AB). The adaptive abilities are linked with general cognitive skills measured with IQ (Hamburg et al., 2019). While the quality of life in both education and social domains are progressing for DS individuals, attention is required to potentially treat the IQ and cognitive difficulties (Baburamani et al., 2019). Their learning consequences are either slower or satisfactory depending on the educational approaches (Leghari and Ali, 2021). Learning processes associated with cultural, and environmental factors is important for DS individuals due to their social requirements and independency (Barbosa et al., 2018; Luna-Garcia et al., 2018 and Kamoun, 2001). Hence, due to their common difficulties in cognitive and fine-motor skills, the potential of individuals with Down syndrome as learners might be perceived as limited (Marques et al., 2015; Jan Blacher, 2002 and Smith & Smith 2021). They face several different problems in daily life activities while walking, talking, chewing, and learning (Jan Blacher, 2002). Down Syndrome people have different cognitive levels of strengths known as memory impairment in childhood and adulthood. A very rare research work has been done on facing problems in accessing technological support to Down Syndrome people.
