Sequential Explanation

1. Overview

A step-by-step interface for exploring exhibit information in order.

Name

• Sequential Explanation

Intent

Present exhibit information in logical categories and let visitors explore at their own pace using clear navigation controls.

2. Target

Problem

Visitors struggle to understand multiple categories of information and may feel overwhelmed or miss key details without structured guidance.

Context

• Exhibits encompass multiple information categories or numerous data points.
• AR feature already activated, ready to display digital content.
• Visitors require a comfortable, self-paced exploration flow.

Use When

• Visitors have engaged the exhibit’s AR information feature.
• A comprehensive, tiered presentation of content is needed.
• Users benefit from explicit controls to move between sections.

Forces

• Cognitive Load: Balancing depth of content with visitor attention span.
• Pacing Control: Allowing users to linger or skip ahead.
• Spatial Context: Ensuring UI elements don’t obstruct the exhibit.
• Consistency: Maintaining a uniform navigation model across categories.

Consequences

Weaknesses:

• Overly linear flow may frustrate visitors seeking serendipitous discovery; UI elements may distract if poorly placed.

Strengths:

• Clear mental model of content structure; users feel in control.

3. Application

Solution

1. Exhibit Information Categorization

• Break down all content into distinct categories (e.g., History, Function, Fun Facts).
• Display a set of buttons or tabs—one per category—at the top or side of the view.

2. Detailed Exhibit Explanation 

• Within each category, present information panels sequentially: images, text, 3D models, or video.
• Highlight key visual components (e.g., animate structural parts) and play aligned audio narration.

3. Navigation Controls 

• Provide “Previous” and “Next” buttons to move between panels.
• Optionally show a progress indicator or step count (e.g., “2 of 5”).

4. Category Indicators 

• Always display the active category title prominently.
• Hide inactive categories to maintain focus.

5. Control for Animated Content 

• For any looping animation or video, include “Pause” and “Resume” controls.
• Auto-pause when users navigate away, auto-resume if they return.

Rationale

• Structuring content into bite-sized, thematically grouped segments reduces overwhelm and gives visitors agency to explore at their own speed, improving comprehension and retention.

Design Parameters

Example

At a natural history exhibit, visitors activate the AR information section and are presented with a sequence of short content panels about the exhibit. They first see a brief introduction, then move through categories such as habitat, anatomy, and scientific significance using Previous and Next controls. Supporting images, 3D highlights, and optional narration help them follow the content step by step at their own pace without being overwhelmed by too much information at once.

Notes

This pattern supports structured, self-directed exploration by guiding visitors through categorized exhibit information at their own pace, enhancing comprehension and engagement.
