After reading Computer Vision for Artists and Designers, I found myself reflecting on how this technology has made its way from industrial and military applications to creative fields like interactive art. One of the points that struck me is how accessible computer vision techniques have become, allowing artists and designers to explore new creative possibilities. It made me think about the similarities and differences between how humans and computers perceive the world. While human vision is complex, combining perception, intuition, and context, computers break down visual input into patterns, often missing the nuances that we take for granted. For example, when we see someone waving, we instantly understand the context — whether it’s a friendly greeting or an attempt to get attention, using cues like their expression and the setting. In contrast, computer vision algorithms like frame differencing detect only the motion of the hand, missing the gesture’s meaning. This shows us how computers rely on measurable inputs, while human vision combines objective information with subjective interpretation.
When it comes to helping computers track what we’re interested in, I think optimizing the physical environment plays a crucial role. The article discusses techniques like proper lighting and camera placement, which seem necessary for improving accuracy. These considerations remind me that even though we can program computers to “see,” there’s still a lot of fine-tuning involved to get the desired results. The tools mentioned, such as Processing and Max/MSP/Jitter, also seem promising for artists who may not have deep programming knowledge but want to experiment with computer vision.
I believe computer vision’s ability to track and surveil raises important questions about its use in interactive art. It offers exciting possibilities, such as creating responsive environments or immersive installations. However, it also introduces concerns about privacy and surveillance, especially when this technology is used outside artistic contexts. In interactive art, it can feel playful and creative, but the same technology in everyday spaces could feel invasive. This duality makes me wonder if we need to establish boundaries around how this technology is used, both for art and for broader societal purposes.
