Speaker & Company Focus

  • Francesca (TG0), Chief Innovation Officer at a London-based startup, discusses touch sensing technologies for industries including automotive, gaming, aerospace, and consumer products.
  • Core theme: the future of tactile interfaces, driven by touch sensing and the integration of new material types.

What “Touch” Means in Interface Design

Francesca breaks down human touch into two categories:

  • Tactile sensations
    • Texture
    • Contact
    • Pressure on the skin
  • Kinesthetic sensations
    • How we move
    • How we perceive the body in space

Note: TG0 focuses more on tactile sensing (not kinesthetic), but both shape how users interact with the world.

Why Today’s Touch Interfaces Look Like Flat Glass

  • Mainstream devices resemble flat touchscreens—often glassy, used primarily via finger sliding/tapping.
  • TG0 traces this design to historical influence from ITO (indium tin oxide):
    • Strengths: transparent and conductive, enabling touch-on-glass surfaces
    • Limitation: cracks when bent, reinforcing today’s mostly rigid, flat form factors

Design Critique: Touchscreens Rely Mostly on Vision

  • The argument: modern touch interfaces underuse tactile information and rely heavily on visual feedback.
  • TG0’s design stance: “good design” should enable more 3D, textural, intuitive, and engaging hand-based interaction—beyond sliding on glass.

Core Materials Direction (Key Technological Concept)

A major shift is enabled by material science:

  • Embed new material properties into non-traditional interface materials
  • Focus on soft, stretchable, conformable materials
    • Including conductive materials used for sensors
  • TG0 predicts soft materials will be central because they avoid rigid glass constraints while still enabling sensing.

Hardware/Software Integration Shift

TG0 emphasizes moving from purely hardware-centric improvements to a software-enabled approach.

They describe an iterative cycle:

  1. Build a hardware/material prototype
  2. Use data + software to analyze performance
  3. Identify what software is missing
  4. Feed insights back into improving the material/hardware properties

This loop is presented as the path to future system improvements.

Advanced Signal Processing + Machine Learning for Richer Gestures

With advanced processing and ML, touch sensing can evolve from:

  • Simple measurement of material response
  • Toward interpreting complex gestures and abstract spatial interactions

TG0 also mentions developing approaches for interpreting how hands move.

Example Product Concepts

Product Concept #1: Consumer Interaction

TG0’s first consumer product uses:

  • An ergonomic, wearable form
  • A plastic base shaped to wrap around the hand
  • Sensing + software to interpret a wide range of finger movements around the device

The “magic interactions” depend on accurately recording hand motion via an embedded sensing layer.

Product Concept #2: Large-Scale “Foam/Seat” Sensing

TG0 explores large-area touch + pressure sensing using conformable materials, potentially scalable beyond small screens.

Examples include soft-surface interactions such as:

  • Interfaces you could sit on
  • Interfaces you could walk onto
  • Interfaces that behave like compliant surfaces

Technical approach:

  • Three simple layers of material for sensing
  • Layered software to extract:
    • gestures
    • user behavior

Example interpretation:

  • Detecting fidgeting (leg movement) as a potential sign of stress using machine learning/signal analysis

Benefits of Simpler, “Monomaterial-ish” Approaches

TG0 argues against overly complex miniaturized stacks as the only direction forward.

Potential benefits of simplifying construction:

  • Lower manufacturing and assembly costs
  • Sustainability improvements
    • Easier recycling
    • Less complex material systems

They position a mono-material approach (or similarly simplified strategies) as more sustainable.

Industry Timeline and Constraints (from Q&A)

  • Not tomorrow: conductive material integration (e.g., graphene) is still often lab-scale, with scaling challenges.
  • Development speed is increasing; TG0 expects meaningful advances in ~5 years for some applications.
  • Repeated question: “killer applications”—these are still being defined.
    • VR is suggested as a driver for consumer demand because it pushes interaction needs beyond flat screens.

Education/Accessibility and Alternative Interaction Modes

  • Children/tactile touch programs: TG0 hasn’t done this yet, but considers it possible.
  • Visually impaired users:
    • Textural feedback (bumpy surfaces under fingers) is discussed as complex.
    • The discussion includes whether touch is the best channel versus alternatives like voice recognition or other remote/modalities.

Societal Pushback vs Plastics

TG0’s perspective:

  • Plastics aren’t inherently bad; the problem is throwaway use
  • Interest in bioplastics, but concern they may lack long-term stability for sensing
  • Expect growth in biocomposite/biomaterial options with conductive properties for sensors/actuators

Obstacles to Applying to Small Devices (e.g., Smartwatches/Phones)

Key factor: required accuracy, depending on the use case.

Scale and form factor affect what’s feasible:

  • Cursor-like interactions may be easier than complex gestures
  • Interface geometry (e.g., circular vs square) changes sensing approaches

TG0’s goal: use the minimum number of material layers while increasing system capability over time.

Target Domains Beyond Touchscreens

Q&A highlights several domains for embedded tactile sensing/actuation:

  • Smart home and automotive
  • VR and games
  • Surgery training and robotics (TG0 indicates they haven’t yet done sensing+actuating projects, but see it as an area of interest)

Chat debate also touched on whether touchscreens will be replaced by VR:

  • Francesca aims to challenge that framing
  • VR expands interaction forms, but TG0 suggests screens/sensors remain relevant
