Concept design Details
According to the World Health Organisation, over 5% of the world’s population suffers from disabling hearing loss. That means that over 360 million people are at risk of not being able to communicate effectively with those around them. In turn, the Deaf often struggle to gain access to employment and to interact socially with their peers. Research conducted in Bulowayo, Zimbabwe suggests that children with severe hearing impairments not only have low reading levels and limited vocabulary, but also that they often feel a sense of isolation and loneliness (Mpofu and Chimhenga 2013). These challenges are also well documented here: http://www.who.int/mediacentre/factsheets/fs300/en/.
Through the application of innovative technologies, I believe that the challenge of effective communication between hearing and Deaf communities can be overcome. That is why I am taking on the challenge of developing and producing a device that can record and translate the hand motions used in South African Sign Language. Because I am from South Africa, I will develop the device with local Deaf communities in mind. It will however be made to be easily transferred to different contexts.By translating Sign Language in real time, the device will allow Deaf people to easily communicate with those who do not know sign language and vice versa. The technology can also be used by non-signers to help them learn Sign Language. It will be especially valuable for parents and educators of Deaf children.
In order to add value to the everyday lives of both Deaf people and those with whom they interact, this technology will have to be accurate and integrate seamlessly into their daily routines. The intention is also for the device to be worn all day. Given these aims, the device must meet the following criteria:
- Light weight - The device must be comfortable and easy to wear. If it is heavy, the device will add to the “gorilla arm syndrome” that has been associated with data glove and gesture recognition devices.
- Minimal and sleek design - The device should look good and be ergonomic.
- Low power/Long battery life - To be useful the device should at the very least have a 12 hour battery life so that the user does not have to charge it throughout the day. They should be able to put it on when they wake up and only have to charge it again when they go to sleep that night. Ideally the device should last several days on a single charge.
- Must not impede daily activities - A user should barely notice that the device is there. This will be a very important feature, since ease and comfort of use will impact on the user’s willingness to communicate through the device. The goal will be to design a device that mimics the sensation of wearing some rings and a wrist watch.
- Reasonable cost - In many parts of the world, particularly developing countries like South Africa - poverty intensifies the negative impacts of hearing impairment. Because my intention is to build something that will bring about significant change in the lives of those who struggle to access adequate education and employment, the device will have to be accessible to as many people as possible. This means focusing very hard on cutting out any unnecessary features. The device must be kept as lean as possible.
- Wireless communications - The device needs to be able to connect with a more powerful processing unit in order to do the translations. Having the device tethered with a wire would be awkward and severely limiting. By using bluetooth (BLE) the device will be able to connect to a smartphone with ease.
- Quick and Accurate translation - Above all else this is the most important criteria. If the device does not translate quickly enough, it will stunt communications and cause frustration. If it does not translate accurately it will cause confusion and would defeat the purpose of the whole device.
