Design and development of a smart device

We are an early start-up. The project we are developing requires that a client could read a text (explanations, instructions) while simultaneously watching the real-life action. We need to contract an engineering/IT specialist to identify possible approaches to the development of hardware and software for the required device(s). As it seems, there are two possible solutions: 1) to adapt one of the models of video (smart) glasses currently available in the market. 2) to design and engineer a new simple model from scratch. Adaptation will be in the direction of the simplification and reduction of functions of more sophisticated models: • No voice • No pictures • No film • Very simple loading capabilities Memory – 500 Mb. GPRS/WiFi connection to a router and/or smartphones. An in advance text loading. Rewind back-forward (by stroking the arch of glasses). Battery – 5 hours Solution for customers already wearing normal optical glasses. Price considerations – a very budget model. Most important! Brand considerations – none. Engineering/IT specialist work results: 1. To prepare terms of reference for an engineering/IT contractor to develop an MVP of the required device. 2. To assess the engineering, software and patent purchase costs of for production of: a. an MVP (10 glasses). b. commercial партия of 10 000 glasses. To provide a short list of potential contractors with track record and approaches to contracting. 3. To create a short list (3) of meeting the required parameters for adaptation. 4. To suggest ways to approach (contract) developers of available smart glasses models.
