This conceptual device reflects the geo-political challenges that refugees face and aims to spark debate about how far technology should go to solving these problems.

The design illustrates a method for fitting a wristband to a parent and child that helps reunite them should they become separated.

The form study was produced whilst studying a masters in design at Cranfield University, UK. Two different 3D printing methods were used; SLA for the creation of the wristband faces and clear window and FDM for all other components. PLA, ABS and wood were used as filaments during the FDM production.

Close-ups showing the FDM and SLA parts. The control screen illustrates the three steps the user would take to apply the wristband to themselves and to their child; the second step enables them to speak into the device to leave a personal message for them to help be identified and be comforted.

The SLA printed wristband faces illustrating the compass arrow that lights up when pointing in the direction of the child and the playful bear face on the child's wristband, the centre button when pressed would activate the compass or parent's message. The wristbands are applied by placing the wrist in the device afterwhich the bands would be automatically wrapped around the wearer's wrist, a quick process reflecting the speed and chaos that could be witnessed in such environments where these devices would need be implemented, such as at boarder crossings, rescue boats or refugee camps.

Ideally such a solution would not need to be developed. This design reflects a possible way to alleviate some of the many problems faced by refugees, however, it does not attempt to challenge the root cause of these issues. Furthermore, a purely technical solution to a humanitarian crisis would fail to consider all the various ways in which people may find themselves in separation from their loved-ones that could not be catered for with one system. Although, in specific circumstances a device like this could be of great use, a combined effort to both tackle the causes of a refugee crisis and attempt to reduce the impacts of the people's challenges could be a way forward. Ultimately, investing in solutions that help refugees improve their standard of living would in itself be a political consideration that would require co-operation from many governments as well as the developers of such technology. Hopefully, the future will hold such collaborative capabilities for technical benefits to be felt by those in the greatest need.
