At the beginning of the design, around the lighting effect for the user to create a sense of surprise, hidden when out, lit a moment enough to attract attention. In the initial sketch stage, I tried a variety of styles, hoping to create a new design language for the brand and look forward to the trend of product serialization. From the light bar to the lamp bead, the color indicator evolves to the graphic icon recognition, the mode switch is more intuitive, and the user interaction experience is improved. Although the design is still in the concept stage, the dot array lamp scheme has been extended to the ITX05 expansion dock, customers can customize the personalized pattern, the product has a higher playability.
