Accessibility Engineering Checklist

Arkeo is designed with accessibility at its core, ensuring that seniors with varying abilities can interact naturally and comfortably with their companion robot.

Visual Accessibility

  • Expressive face + animated LEDs give clear status feedback
  • High-contrast, customisable colour palette
  • Expressions sync with speech
  • Welcoming bust with soft silicone skin helps first-time users feel at ease.

Auditory Accessibility

  • Customisable voice (tone, language) and volume via speakers
  • Clear speech synthesis
  • Can relay calls/messages so socially isolated seniors stay in touch

Physical Accessibility

  • Fully voice-operated, no physical interaction required, ideal for users with limited mobility
  • Low-effort deployment, lightweight design (5 kg) allows users to easily relocate the unit.
  • Low-profile footprint, it's compact bust design fits easily into small living spaces
  • Stable base design prevents accidental tipping

Cognitive Accessibility

  • Intuitive, adaptive interaction flows that match the user's pace and abilities
  • Clear, natural language without jargon or complex instructions
  • Consistent, predictable behavior to reduce cognitive effort and build confidence
  • Context-aware memory aids and proactive, gentle reminders for daily routines
  • Personalized support that adapts over time to individual habits and cognitive needs

Privacy & Security

  • Local processing minimizes data transmission
  • Transparent data usage with simple consent management
  • Camera processes video in real-time without recording
  • Regular security updates with user notification

Language & Culture

  • Multi-language support including regional dialects
  • Cultural sensitivity in conversation patterns
  • Customizable personality and communication style
  • Local emergency services integration by region
