# Trial System Overhaul - Complete
|
|
|
|
## Overview
|
|
|
|
The HRIStudio trial system has been completely overhauled to use the established panel-based design pattern from the experiment designer. This transformation brings consistency with the platform's visual programming interface and provides an optimal layout for wizard-controlled trial execution.
|
|
|
|
## Motivation
|
|
|
|
### Problems with Previous Implementation
|
|
- **Design Inconsistency**: Trial interface didn't match experiment designer's panel layout
|
|
- **Missing Breadcrumbs**: Trial pages lacked proper navigation breadcrumbs
|
|
- **UI Flashing**: Rapid WebSocket reconnection attempts caused disruptive visual feedback
|
|
- **Layout Inefficiency**: Information not optimally organized for wizard workflow
|
|
- **Component Divergence**: Trial components didn't follow established patterns
|
|
|
|
### Goals
|
|
- Adopt panel-based layout consistent with experiment designer
|
|
- Implement proper breadcrumb navigation like other entity pages
|
|
- Optimize information architecture for wizard interface workflow
|
|
- Stabilize real-time connection indicators
|
|
- Maintain all functionality while improving user experience
|
|
|
|
## Implementation Changes
|
|
|
|
### 1. Wizard Interface Redesign
|
|
|
|
**Before: EntityView Layout**
|
|
```tsx
|
|
<EntityView>
|
|
<EntityViewHeader
|
|
title="Trial Execution"
|
|
subtitle="Experiment • Participant"
|
|
icon="Activity"
|
|
status={{ label: "In Progress", variant: "secondary" }}
|
|
/>
|
|
|
|
<div className="grid grid-cols-1 gap-8 lg:grid-cols-4">
|
|
<div className="lg:col-span-3 space-y-8">
|
|
<EntityViewSection title="Current Step" icon="Play">
|
|
{/* Step execution controls */}
|
|
</EntityViewSection>
|
|
<EntityViewSection title="Wizard Controls" icon="Zap">
|
|
{/* Action controls */}
|
|
</EntityViewSection>
|
|
</div>
|
|
|
|
<EntityViewSidebar>
|
|
<EntityViewSection title="Robot Status" icon="Bot">
|
|
{/* Robot monitoring */}
|
|
</EntityViewSection>
|
|
<EntityViewSection title="Participant" icon="User">
|
|
{/* Participant info */}
|
|
</EntityViewSection>
|
|
<EntityViewSection title="Live Events" icon="Clock">
|
|
{/* Events log */}
|
|
</EntityViewSection>
|
|
</EntityViewSidebar>
|
|
</div>
|
|
</EntityView>
|
|
```
|
|
|
|
**After: Panel-Based Layout**
|
|
```tsx
|
|
<div className="flex h-screen flex-col">
|
|
<PageHeader
|
|
title="Wizard Control"
|
|
description={`${trial.experiment.name} • ${trial.participant.participantCode}`}
|
|
icon={Activity}
|
|
/>
|
|
|
|
<PanelsContainer
|
|
left={leftPanel}
|
|
center={centerPanel}
|
|
right={rightPanel}
|
|
showDividers={true}
|
|
className="min-h-0 flex-1"
|
|
/>
|
|
</div>
|
|
```
|
|
|
|
### 2. Panel-Based Architecture
|
|
|
|
**Left Panel - Trial Controls & Navigation**
|
|
- **Trial Status**: Visual status indicator with elapsed time and progress
|
|
- **Trial Controls**: Start/Next Step/Complete/Abort buttons
|
|
- **Step List**: Visual step progression with current position highlighted
|
|
- **Compact Design**: Optimized for quick access to essential controls
|
|
|
|
**Center Panel - Main Execution Area**
|
|
- **Current Step Display**: Prominent step name, description, and navigation
|
|
- **Wizard Actions**: Full-width action controls interface
|
|
- **Connection Alerts**: Stable WebSocket status indicators
|
|
- **Trial State Management**: Scheduled/In Progress/Completed views
|
|
|
|
**Right Panel - Monitoring & Context**
|
|
- **Robot Status**: Real-time robot monitoring with mock integration
|
|
- **Participant Info**: Essential participant context
|
|
- **Live Events**: Scrollable event log with timestamps
|
|
- **Connection Details**: Technical information and trial metadata
|
|
|
|
### 3. Breadcrumb Navigation
|
|
```typescript
|
|
useBreadcrumbsEffect([
|
|
{ label: "Dashboard", href: "/dashboard" },
|
|
{ label: "Studies", href: "/studies" },
|
|
{ label: studyData.name, href: `/studies/${studyData.id}` },
|
|
{ label: "Trials", href: `/studies/${studyData.id}/trials` },
|
|
{ label: `Trial ${trial.participant.participantCode}`, href: `/trials/${trial.id}` },
|
|
{ label: "Wizard Control" },
|
|
]);
|
|
```
|
|
|
|
### 4. Component Integration
|
|
|
|
**PanelsContainer Integration**
|
|
- Reused proven layout system from experiment designer
|
|
- Drag-resizable panels with overflow containment
|
|
- Consistent spacing and visual hierarchy
|
|

|
**PageHeader Standardization**
|
|
- Matches pattern used across all entity pages
|
|
- Proper icon and description placement
|
|
- Consistent typography and spacing
|
|
|
|
**WebSocket Stability Improvements**
|
|
```typescript
|
|
// Stable connection status in right panel
|
|
<Badge variant={wsConnected ? "default" : "secondary"}>
|
|
{wsConnected ? "Connected" : "Polling"}
|
|
</Badge>
|
|
```
