Orange computing: Challenges and opportunities for affective signal processing

As the growth of economy and technology has become increasingly rapid, mental care is getting more important today. However, recent movements, such green technologies, place more emphasis on environmental issues but less on mental care. Therefore, this paper presents a newly emerging technology called orange computing for mental care applications. Orange computing refers to health, happiness, and physiopsychological care computing, which focuses on designing algorithms and systems for enhancing body and mind balance. The representative color for orange computing comes from a harmonic fusion of passion, love, and happiness. In order to demonstrate the main idea of orange computing, in this work we also discuss affective signal processing, one of the important topics in orange computing. Besides, a case study on the emotion speech recognition system for emotion care services is presented at the end of the paper. Experimental results show that the proposed system can enhance the accuracy rate by 4.44% on average. In contrast with the baselines, the proposed system can identify emotion speeches more precisely, subsequently demonstrating the feasibility and effectiveness of the system.
