<p>With the continuous development of digital art, traditional ink painting creation is faced with the challenge of how to combine with modern technology. The application of photoelectric sensors makes the interaction between art creation and computer technology more convenient, and the development of low-energy computers provides new possibilities for sustainable art creation. The photoelectric sensor is used to capture the artist's painting action in real time, and the data processing and feedback are carried out by low energy computer. Firstly, the interface between photoelectric sensor and computer is established to realize information interaction. Then, through the development of special software, the real-time monitoring and digital transformation of ink painting process is realized. To ensure low power operation of the system, we chose a low power processor and optimized the algorithm to reduce the consumption of computing resources. The experimental results show that the ink assisted creation system designed in this paper can effectively capture the subtle movements of the creators and improve the creation experience through real-time feedback. The energy consumption of the system under standard workload is much lower than that of the traditional computer system, which verifies the feasibility of low energy calculation in art creation.</p>
