Interactive presentations: when the viewer needs a choice

In an interactive presentation, the user's actions determine the viewing sequence. People can open a section, inspect an object, select a feature or return to a comparison. Consider this format when different viewers bring different questions. The main design task is to make those choices understandable and connect them to content that helps explain the subject.

Compare it with a linear presentation

A film has a fixed sequence that can suit a shared introduction. An application allows a different order, but needs additional decisions: where is the user, what can they select and how do they return? If there are few options and everyone needs the same sequence, interaction may be unnecessary. In other cases, it lets a presenter follow a client's question without searching through a long film or repeating sections already understood.

Prioritise structure over screen count

Before visual design, list the objects and the questions associated with them. A catalogue may need categories, individual items, specifications and related material. Each section needs an understandable entry, and equivalent actions should behave consistently. Animation should not conceal incomplete data. Decide which fields are required and what appears when an image or description is missing. This makes the structure usable when the content is updated later.

Design for the actual device

A touch display, desktop computer and handheld device require different interaction checks. Consider viewing distance, input precision and whether people will use the system without assistance. A public kiosk needs a return to its starting state and predictable behaviour after inactivity. A presentation led by a salesperson may instead depend on quick movement between sections. Describe these scenarios separately, even when they share the same content collection.

Hand over an operable tool

Delivery includes the agreed version, launch material and instructions. If the client will replace content independently, demonstrate that process with a typical change. Check the main routes, search or filters where present, media playback and responses to unavailable data. Record supported devices and limitations at handover. An interactive presentation becomes a working tool when its intended team can operate and maintain it, rather than only view a demonstration on the developer's computer.
