presentation for english class

I need a 7-9 minutes presentation. everything that you have to know is in the below.

you are going to present on a low-key technology or innovation that benefits a spesific group of people. you may not choose any widespread technologies such as cellphones, computers, internet and so on.

you are going to give a presantation showing evidence of research. 

you must present using an appropriate PowerPoing that includes evidence of research. in your presantation, you will include a photo of the innovation. explain, using your own words, what the innovation or technology does and how it works. please note, "people" is not appropriate response to this question. you must specify where these people live, what age they are, and why this innovation is beneficial for them specifically. you will need to research the innovation more deeply to find out if it is really being used and by whom. Finally, you will also analyze whether this innovation would be useful in the US and in your home country. this final point requires that you think carefully about the innovation's purpose and the current state of affairs in the two countries. 

please note, although you are using outside sources to prepare your presentation, you cannot use any of the text used in the article of the video. this means that you will not need to paraphrase, summarize and reword any information that you use.
