The bottom one is the first one that involves the elderly using the calculator for them.It has a stick to hold on and also big numbers to press.The idea did not work due to the advice of mr irfan to not use it.So changed essential question to being not talking with the elderly.Changed and improved on but failed as needed prototype and not feasible so changed to walking stick with a portable seat and also a flag to warn others an elderly is crossing the road
