This research establishes a preliminary theoretical framework comparing visual and tactile information graphics to inform accessible data representation for blind and low vision individuals. The analysis reveals that while encoding and cognitive benefits share similarities, fundamental differences in perception necessitate a tactile-first design approach.

Key insights

  • Benefits related to data encoding and higher-level cognition are broadly similar across visual and tactile modalities, indicating shared abstract advantages of information graphics.
  • Perceptual mechanisms constitute the most significant area of divergence, with tactile perception being inherently sequential and slower compared to the rapid, parallel processing of visual information.
  • A 'tactile-first' design philosophy is essential; direct translations of visual graphics are often ineffective due to the distinct capabilities and limitations of haptic perception.
