What is a defining characteristic of interactive art?

Interactive art is defined by its engagement with the audience, often incorporating technology that allows viewers to participate in or influence the artwork. The use of computers or motion sensors is a common feature of interactive art, enabling real-time responses and transformations based on user interactions. This characteristic sets interactive art apart from more traditional art forms, as it breaks the barrier between the artwork and the audience, making them active participants in the artistic experience.

In contrast, the other choices describe characteristics that do not align with the essence of interactive art. For example, stating that it is a solitary experience with no audience participation or that it is created in a public space without viewer engagement does not reflect the inherently participatory nature of interactive art. Additionally, a focus on traditional painting techniques suggests a static form of artistry that lacks the dynamism associated with interactive experiences, further illustrating why the use of technology is a defining characteristic.
