HRIStudio Structure and Requirements

Structure

A study is a general term for a research project.

An experiment is a specific set of steps and actions that will be conducted with a participant and robot.

An trial is a specific instance of an experiment. It is a single run of the experiment with a specific participant and robot.

A step is a general term for something that is being done in the experiment. It is represented as a collection of actions that are being done in a specific order.

An action is a specific operation that is being done (like "move to position", "press button", "say something", etc.) These are the smallest atomic units of the platform.

A participant is a person that has been added to a study. This person does not have an account.

A user is a person that has an account, which is a person that has been added to a study. Anyone can sign up for an account, but they must be added to a study or create their own. A user can have different roles in different studies.

Roles and Permissions

Core Roles

1. Owner

   • Single owner per study
   • Full control over all aspects of the study
   • Can delete study or transfer ownership
   • Can manage all other roles
   • Usually the study creator or designated successor
   • Cannot be removed except through ownership transfer

2. Admin

   • Multiple admins allowed
   • Can manage participants, experiments, and study settings
   • Can invite and manage other users (except Owner)
   • Cannot delete study or transfer ownership
   • Appointed by Owner

3. Principal Investigator (PI)

   • Scientific oversight role
   • Full access to participant data and experiment design
   • Can manage experiment protocols
   • Can analyze and export all data
   • Cannot modify core study settings or manage user roles
   • Typically one PI per study

4. Wizard

   • Operates the robot during experiment trials
   • Can control live experiment sessions
   • Can view anonymized participant data
   • Can annotate experiments in real-time
   • Cannot modify study design or access sensitive participant data
   • Multiple wizards allowed

5. Researcher

   • Can view and analyze experiment data
   • Can access anonymized participant information
   • Can export and analyze results
   • Cannot modify study design or participant data
   • Cannot run experiment trials
   • Multiple researchers allowed

6. Observer

   • Can view live experiments
   • Can view anonymized participant data
   • Can add annotations
   • Cannot modify any study aspects
   • Cannot access sensitive data
   • Multiple observers allowed

Permission Categories

1. Study Management

   • Create/Delete Study (Owner only)
   • Edit Study Settings
   • Transfer Ownership (Owner only)
   • Manage Study Metadata

2. Participant Management

   • Add/Remove Participants
   • View Participant Details (identifiable vs. anonymized)
   • Edit Participant Information
   • Manage Participant Consent Forms

3. Experiment Design

   • Create/Edit Experiment Templates
   • Define Steps and Actions
   • Set Robot Behaviors
   • Configure Data Collection

4. Experiment Execution

   • Run Experiment Trials
   • Control Robot Actions
   • Monitor Live Sessions
   • Add Real-time Annotations

5. Data Access

   • View Raw Data
   • View Anonymized Data
   • Export Data
   • Access Participant Identifiable Information

6. User Management

   • Invite Users
   • Assign Roles
   • Remove Users
   • Manage Permissions

Role-Permission Matrix

Experiment Design	Full	Full	Full	No	No	No

Special Considerations

1. Data Privacy

   • Identifiable participant information is only accessible to Owner, Admin, and PI roles
   • All other roles see anonymized data
   • Audit logs track all data access

2. Role Hierarchy

   • Owner > Admin > PI > Wizard/Researcher > Observer
   • Higher roles inherit permissions from lower roles
   • Certain permissions (like study deletion) are restricted to specific roles

3. Role Assignment

   • Users can have different roles in different studies
   • One user cannot hold multiple roles in the same study
   • Role changes are logged and require appropriate permissions
