You are a Computer Systems Architect at Mahlaseli, a local startup that aims to use non-invasive next generation technology to promote health and wellness among people through knowledge of and adherence to healthy lifestyle practices. Research is showing that most diseases can be prevented or successfully managed through simple and healthy lifestyle habits including eating healthy foods, drinking pure water regularly, engaging in regular physical exercise and resting sufficiently.

One of the specific projects that Mahlaseli would like to undertake involves development of a system that uses smart glasses for diet tracking and coaching. Smart glasses are believed to be one of the next big breakthrough applications in the field of wearable technology. Conceptually, smart glasses are eyewear that uses a mix of different technologies to merge what the user sees in the real world with virtual information, typically overlaid on one of the lenses of the glasses.
