During the second phase, we worked on the selecting which functions were necessary for Ring. The use of a touch sensor and standard vibration technology resulted in higher power consumption, resulting in quick battery loss. With that in mind, we devised various ideas in accordance with the specifications needed to reduce consumption and became particularly focused on the miniaturization of Ring, for the final phase of development. We have reviewed the designing processes over and over and have designed software for storing all Ring’s necessary functions into a small device.
