Autism is a developmental disorder that appears in early childhood and the most common condition is known as autism spectrum disorders (ASD). It can be difficult to diagnose, as symptoms and degree of impairment are different for every child.
One in 150 children in Singapore has autism. There were 4,400 such children in 2014, a 76 per cent jump from the 2,500 children in 2010.
Microbit allows the autistic kid to make certain movement or press certain buttons to express their feelings. For eg. When asking for help or getting emotionally overwhelmed, the kids are able to press respective buttons to call out to caregivers. The microbit also releases an alert sound to suggests immediate attention for the kids.
The autistic kid will be holding on to the microbit connected to a Raspberry Pi. The LED light connecting to the Raspberry Pi will light up if the child is a certain distance away from the child. This allows the caregiver to locate the distance between the child and them. This ensures that the caregivers are able to supervise their child from being exposed to unfamiliar surroundings.
When the autistic child is agitated and emotionally unstable, eg. Angry, Upset. The child can press the right button to notify the caregiver and request for their attention. Thus, a "help" signal from the microbit will be shown and the microbit will have a continuous "beep" sound to alert caregivers to come and attend to the autistic child.
Through the Raspberry Pi connected to the LED light and range sensor, we are able to simulate the heart rate of a autistic child. If it exceeds the normal heart rate range of their age, the LED light will light up and alert the caregiver. This is useful when the autistic child is too afraid to express their feelings and will also allow the caregivers to better understand their feelings and emotions.
A speaker would be needed if we want to alert the caregiver of the autistic kid to provide immediate attention. Without a speaker connected to the microbit, alert sounds cannot be produce therefore the caregiver might not take note that the autistic child actually requested for immediate help.
If the autistic child just happen to shake the microbit accidentally, it might result in a false alarm for the caregivers.
It would be better if the microbit could have calming/soothing music effects played to them.This would keep them occupied and calm them down for the time being before the caregiver arrive and attend to them.
It would be better if we can also implemment a location app inside the tracker as the range sensor is unable to capture a wide and long distance.Hence by implementing a location tracker, the caregiver of the autistic child could easily track and know where the kid is at all times to avoid unwanted mishaps.
