Design Example: Resistive Touchscreen01:14

Design Example: Resistive Touchscreen

460
A device engineer plays a crucial role in designing user interfaces for mobile devices. One such interface is the resistive touchscreen, which fundamentally consists of two metallic layers: a flexible upper layer and a rigid lower layer, separated by a narrow gap. The high resistance between these two layers is a key characteristic of this design.
When a user touches the screen, the two layers make contact at a specific point known as the touchpoint. This contact reduces the resistance between...

iPS Cell Differentiation01:22

iPS Cell Differentiation

2.8K
The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.

Somatosensation01:33

Somatosensation

39.0K
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

Area of Science:

  • Rehabilitation Medicine
  • Human-Computer Interaction
  • Rheumatology

Background:

  • Impaired hand function significantly impacts scleroderma patients' quality of life.
  • Interaction with touchscreen devices presents challenges for individuals with scleroderma.

Purpose of the Study:

  • To assess scleroderma patients' performance on a novel touchscreen application.
  • To identify specific touchscreen features that hinder or aid use by scleroderma patients.
  • To explore the potential of touchscreen technology in physiotherapy for scleroderma.

Main Methods:

  • Eighty scleroderma patients and eighty healthy controls used a touchscreen application with games testing tapping, dragging/dropping, and pinching-to-zoom gestures.
  • Performance metrics were compared between scleroderma patients and controls.
  • The 10 worst-performing scleroderma patients participated in a home-based physiotherapy trial using a modified application.

Main Results:

  • Scleroderma patients demonstrated significantly poorer performance across all tested gestures compared to healthy controls.
  • Specific touchscreen interaction elements negatively impacting performance were identified.
  • Preliminary results suggest potential benefits from a modified touchscreen application for home-based physiotherapy.

Conclusions:

  • Guidelines can be developed for designing more accessible touchscreen interfaces for scleroderma patients.
  • Touchscreen technology holds promise for integration into self-administered physiotherapy programs for managing scleroderma-related hand impairments.
