A new smart school bag that ensures it is correctly packed for each day’s timetable has been developed by engineers from
Deakin University.
It uses radio frequency identification (RFID) tags to detect items in the bag and Internet of Things Technology (IoT), which extends internet connectivity to everyday objects.
The bag was designed by Dr Hamid Abdi alongside Masters students Jayadev Ajayakumar, Naga Venkata Durga Surendra Anna and Lahiru Abeysekara. It comes with built-in hardware and software and has the capacity to send content alerts by smartphone to students, parents and teachers.
“RFID technology allows any user to detect items in a contactless way,” Dr Abdi says. “For example, when you return books to libraries, you put a number of books on top of each other and the system will automatically detect which books you are returning without scanning all of the barcodes.”
The smart school bag can also tell what items are not required, ensuring that the bag is no heavier than it needs to be.
“At the same time we wanted to minimise the weight of the bag to reduce the discomfort children experience carrying a heavy load on their backs and shoulders,” Dr Abdi says.
Although RFID technology is currently mainly used in industry supply chains, its low cost and relatively low level of complexity meant Dr Abdi saw it as a viable technology for his invention.
Schools or parents can enter data about the activities of each day to the system’s IoT server. The server then links these activities to the RFID tags placed on the items needed. “After we know what activity is happening from the IoT server, we can tell what items are needed,” Dr Abdi says. “For instance, if I have a math class and I need my math book, the server will link that activity with the item.”
The smart school bag also works in conjunction with a mobile application which lets parents see the items in the bag and check them off against the timetable.
“We know packing the school bag each morning can be difficult, especially for younger kids, because the timetable changes daily and each day they need to pack different things,” Dr Abdi says. “We think the smart school bag will save a lot of time and stress that occurs when homework, hats or lunches are left home by mistake, especially if that requires parents to quickly race home to collect the missing item.”
Dr Abdi was inspired to create the school bag after a personal experience with his son.
“I remember it was a really rainy and cold Monday morning in 2017,” he says. “I took my son to the kiss and drop at school and he said, ‘Daddy, I forgot my guitar!’”
Dr Abdi noticed that his son then became stressed and upset with himself. “We drove home to get it and on the way back to school, we had minimal conversation,” he says. “In the afternoon when I came to pick him up I said, ‘Look, whatever happens, I love you,’ and it was only then that my son started to come out of his small depression.”
Following this experience, Dr Abdi spent one year trying to quantify the added value of this technology for families in terms of saving time and stress. “We started working on this project when I became sure that this was a useful thing,” he says.
Although the system can be fitted to any school bag, Dr Abdi and his team have designed a prototype smart school bag which includes the smart phone application and could retail for between $125 and $150.
Dr Abdi is now working on ensuring the smart school bag’s associated mobile application is functional and user friendly. “We want to make things intuitive and easy and help the user enjoy their experience in using this technology,” he says.
Dr Abdi and his team are also looking for commercial partners to take the project to the next level.
“We are looking for anyone that has a genuine interest in this technology for the health of the community and the health of future kids,” he says.
