Self-critique & future development
Through walking the whole process of this project, the biggest challenge is to solve the problem of colours to express the tones. From the ananlysis of research, we found that it’s impossible for everyone to have same definition of colours. Therefore, self-defined colors have become the goal of iteration. However, if the number of self-defined colors increases gradually, it is likely that the user will not remember what the color represents, so "when the user receives the tone from the other users, how to make the meaning of the tone effectively reminded?" This will be the direction to work on for future iterations. On the other hand, in the future direction, this application may be able to combine with existing wearable devices, such as, apple watch, and may achieve more humane and convenient effect, so that the interaction between people is not only between words, but also gives a new mode of interaction, and is more immediate and convenient.
