Demos/Prototypes Already Completed

List of demos already developed at AIMS Lab:


Autism Barta, Automatic Autism Screening Tool


To increase autism awareness and education in rural Bangladesh, we have proposed an interactive approach called “Autism Barta’’, a mobile interactive, culture- sensitive, community-based screening tool for autism. This automated screening tool will streamline referrals for Autism assessment and intervention. Community health workers (or parents) will use Autism Barta in rural settings to screen children for possible autism. Once a child screens positive, Autism Barta will connect the family with Autism resources (i.e. nearby Assessment and Intervention Centre) for diagnosis and intervention. Autism Barta will create awareness and new marketable skills around autism in communities that will enhance sustainability. Autism Barta also uses telecommunication networks to transfer data for referral, assessment and monitoring.

Communication Aid for Non-Verbal Kids


Communication Aid helps people with speech or learning difficulties to communicate. For children and adults alike, Communication Aid supports people with a range of disabilities such as autism, aphasia, dysarthria, dyspraxia, cerebral palsy, and those recovering from a stroke. It offers a wide range of symbol solutions or text writing with human spoken voicing for the user, or a caregiver or family member to set up for an individual user which is ideal for those with autism.

Smart Cane for Blind


Smart Cane device is an electronic travel aid which fits as handle of the white cane. As white cane can only detect obstacles up to knee height, Smart Cane compliments its functionality by detecting obstacles from knee to head height. It detects obstacles using sonic waves and the presence of obstacles is conveyed through intuitive vibratory patterns. It is powered using rechargeable Li–ion battery like cell phone and can be used in both indoor and outdoor navigation modes. It has been designed to accommodate varying types of user grips which are commonly used by visually challenged. At this moment we prototyped it (left figure), however, our future plan to extend this design with integration of GPS and voice to identify the location and system will able to tell the blind user where they are located so they can have better accessibility.

Disable Child Tracking


The Disable Child Tracking is a durable, child-friendly product that allows children to call a parent through the touch of a SOS button, as well as allows parents to call and track their kids. There are multiple attachment accessories available, giving children and parents options for how to wear the device. With no screen, it does not allow for internet access or texting, protecting kids from cyber-bullying or content that is not age appropriate. Parents are able to quickly access their child’s real-time whereabouts via an online portal or mobile phone app.

Disable Tracking during Disaster


When a disaster strikes, it is quite tough for the disabled persons, specially the visually and physically challenged people to move into safe places rather than others. During the time of disaster, a disabled person can send a signal using the SOS button of the device. Then the SOS message is sent to the rescue teams and tracking signal is generated using which the rescue team can locate the sender using GPS.

e-SQUEEZE MACHINE for reducing Anxiety of Autistic Children


Electronic SQUEEZE MACHINE (e-SQUEEZE MACHINE) has been comprehended through years of researches and observations that deep pressure stimulation has a calming effect on many children with psychiatric disorders. Deep pressure stimulation, such as rolling up in a gym mat, has been used to calm children with Autism Spectrum Disorder (ASD) and Attention Deficit Hyperactivity Disorder (ADHD). The original squeeze machine was invented by Dr. Temple Grandin, USA and it is currently supplied by Therafin Corporation, USA with costs around 5000.00 USD.

The advantage of the squeeze machine over other forms of deep pressure stimulation, such as rolling in mats, is that the machine can apply greater amounts of pressure over larger areas of the body. The device applies constant pressure, even when the user shifts position. The design of e-SQUEEZE MACHINE is same as the one developed by Therafin Corporation, USA; however, this model uses an electric linear actuator instead of a hydraulic one. As a result, there is more control over the degree of pressure that can be applied to the patient.

The future plan is to develop SMART SQUEEZE MACHINE that will integrate electronic sensors to digitally read physiological information from the patient’s body. It is intended to make the Squeeze Machine smarter and completely autonomous and interactive. This project jointly developed by Proyash and AIMS Lab.
