The TrewGrip keyboard is a keyboard that is made in such a way that the keys are at the back and you have to type by feel. The keyboard is connected to the user’s smartphone or tablet through Bluetooth. According to the company that manufactured it, this keyboard would be more ergonomic and would allow typing at a faster rate than a normal keyboard by reaching around. This is because the fingers would be more comfortable at that natural position. If you are an aspiring accordion player, this keyboard could help you achieve your dreams.
