The idea for this unit, which I think is my most adventurous yet, came to me first thing one morning whilst I was lying in bed desperately trying not to think about work. In the unit, students work in teams to combine hardware and software in the production of a system which allows them to remotely guide a blindfolded peer. Beyond the ICT aims, it provides students with an understanding of the world as experienced by the visually impaired, as well as the ways in which ICT can be used to augment and improve the lives of people with disabilities.
The system is entirely student-assembled and centers around a head-mounted web cam and freely available software. Being a new school, we do not teach Home Economics or Design Technology, so this unit provided our students to work in a hands-on fashion that they do not often experience. In total, the cost of running the unit should be less than HKD$200 (USD$25) per group, assumming you do not need to purchase any laptops. The materials below should guide you through the process of running this unit.
Thanks to Coco, a very artistic student from my school who was kind enough to create a lovely logo for this unit!
