Design Example: Resistive Touchscreen01:14

Design Example: Resistive Touchscreen

361
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...

Learning Disabilities

220
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

Social Facilitation01:04

Social Facilitation

32.0K
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Barriers to Effective Communication II01:21

Barriers to Effective Communication II

3.7K
The barriers to effective communication also include cultural barriers, semantic barriers, gender barriers, and time constraints.
Cultural barriers:
Differences in values, beliefs, religion, knowledge, and tradition can significantly impact communication. Awareness of nonverbal cues is critical, especially when conversing with a patient from a different culture. What appears appropriate in one culture may be inappropriate in another.
Semantic barriers:
As a result of their tendency to use...

Stereotype Content Model02:16

Stereotype Content Model

14.8K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Barriers to Effective Communication I01:30

Barriers to Effective Communication I

9.0K
A communication barrier is any distortion or interruption during a conversation, resulting in miscommunication of the message. A good communicator should know these barriers and continuously check for the listener's understanding by obtaining feedback.
Communication barriers include the following:
Physiological barriers: They are limitations caused by a person's health condition or disability, such as hearing loss, poor eyesight, illness, or unconsciousness. An example to overcome this...

Area of Science:

  • Human-Computer Interaction
  • Accessibility Research
  • Web Design

Background:

  • Cognitive accessibility focuses on making digital content usable for individuals with cognitive impairments, including the elderly and those with intellectual disabilities.
  • Designing user interfaces with cognitive considerations is crucial for inclusivity.
  • Existing web content often presents challenges for users with cognitive impairments due to complex language and structure.

Purpose of the Study:

  • To present cognitive accessibility design patterns.
  • To apply these patterns in the development of the Easier web system's user interface.
  • To evaluate the cognitive accessibility and user experience of the Easier system.

Main Methods:

  • Development of cognitive accessibility design patterns.
  • Implementation of these patterns in the Easier web system, a tool for text simplification.
  • User testing with individuals with intellectual disabilities and older adults.

Main Results:

  • The Easier system successfully applied cognitive accessibility design patterns.
  • User tests demonstrated that individuals with cognitive impairments could effectively use the interface.
  • Participants reported a satisfactory user experience with the Easier system.

Conclusions:

  • Cognitive accessibility design patterns are effective in creating usable web interfaces for people with cognitive impairments.
  • The Easier system provides a valuable tool for enhancing text understanding and readability.
  • A validated design proposal for a glossary mechanism in simplified web interfaces was developed.
