The starting point
A useful interactive-art brief explains who the experience is for, where it will operate, what people should be able to do and how success will be assessed. Describe the human experience before specifying the technology.

Start with one human action
Imagine someone arriving without having read a description. What invites them in? What can they change? How will they know that their action has made a difference? These questions turn an ambition such as “community engagement” into something a creative team can explore. They also help distinguish a shared spectacle from an experience that requires individual participation.
Describe the place as well as the artwork
Share the site, available plans and photographs, operating dates and likely viewing positions. Note neighbouring activities, access constraints and whether people will pass through or make a deliberate visit. A festival garden, a library and a crowded forecourt offer different conditions. Identify what is known and what needs a site visit; uncertainty is useful information when it is visible in the brief.
Use a precedent to explain the interaction
In RIPPLE, a person’s input influences a water-based audiovisual environment. ECHO/OHCE turns a participant’s portrait into part of a large public sculpture. These are different invitations. Link to the project that best expresses your interest, then explain what you want to learn from it. Asking for a related feeling or interaction is more useful than assuming an existing artwork can be copied onto a new site.
Separate creative intent from delivery responsibilities
List the people who will approve content and the partners who control the venue, equipment, installation and operation. Say whether you are seeking concept development, content, an installation or a wider production. Include the planning window and any budget range already available. A budget is a scoping tool; leaving it unstated does not remove the need to agree what is included.
Plan participation and care together
Consider who might prefer to watch, who may need another way to participate and how staff will explain the experience. Where faces, voices or personal contributions are involved, agree permissions and how content is handled. Moderation, storage and deletion are design questions to resolve before capture begins. Access and consent should be part of the creative discussion, rather than additions after the interaction is built.
Choose an outcome you can actually observe
“People felt connected” is an intention, not an evaluation result. Decide what evidence would help you understand the experience: completed interactions, waiting time, participant reflection or responses to a particular learning question. If the aim concerns precinct activity, agree a suitable comparison and partner data before the event. Start with a small set of measures the team can realistically collect.
Bring a first brief, not a finished solution
The first conversation can begin with one page: audience, site, dates, desired interaction, partners, budget context and open questions. The public commissioning checklist provides a starting structure. A concept call request starts that discussion; it does not reserve a production slot or establish a price.

Prepare your brief
Use the public briefing checklist, explore interactive public art or projection mapping, then request a concept call.
