NailO is also engineered for personalization. Users can attach surface art of their choice to the trackpad, giving the function some form-an integral part of any wearable device, and one that many innovators might not be giving enough attention. In its current design, the trackpad lays over the circuit board housing the processor, sensing chip and Bluetooth radio. NailO is therefore a little thicker than nail art; however, downsizing the device is part of the developers' aims for the future. According to an article from Computerworls.com, the team is already talking to manufacturers in China about a battery that is only half a millimeter thick.
