Visual content in social media and networks has become more important with the emphasis on storytelling using pictures. One reason is that the human brain processes visual images 60,000 times more quickly than written text. Visuals capture our attention and can lend clarity to written text. Additionally,

 

  • On average, people spend more than 2 hours on social media daily, and during the COVID pandemic quarantine that time increased (Hernandez, 2021). 
  • 63% of social media is made up of images.  
  • Nearly half of all Internet users have reposted a photo or video they have found online.  
  • 54% of Internet users have posted an original photo or video that they personally have created. 
  • Content with relevant images gets 94% more views than content without (Lee, 2014).

 

There are many types of visuals you can choose to use or create including creative photography, video, screenshots, infographics, data visualization (charts and graphs), comics, memes, visual note-taking, and miscellaneous graphics (Lee, 2014). Additionally, PowerPoint and Prezi are commonly used to make presentations.

 

Marketing researchers have identified that what captures viewers’ attention best are visuals with low cognitive demand and high clarity, meaning that they can be quickly understood (Hernandez, 2021).

 

Therefore, we provide some brief guidelines to help readers become more effective in the visual images that they select, curate, and create.

____________________________________________________________________________

 

Use faces in your visuals.

  • People have evolved to pay attention to human faces and what they are looking at (Hernandez, 2021).

 

Keep visual content clean.

  • If your visual image is too complex or cluttered, it will increase cognitive demand and reduce clarity (Hernandez, 2021).

 

Create a center of attention.

  • Usually, viewers will focus on the front and center of the visual image. This is where you want to place the most important visually idea (Hernandez, 2021).

 

Use high-quality graphics

  • Resolution matters. Low-resolution images will look fuzzy, especially if you are projecting your visuals.

  • Copyright also matters. It is tempting to copy images from the internet but can get you in legal trouble.

  • Some sources provide high-resolution images that are no- or low-cost and copyright-free. You can begin with clip art provided with Microsoft products. Other sources include Flickr, Pexels, Unsplash, and Getty Images (Lee, 2014).

 

Use visual image-creation tools.

  • These tools can help create effective visuals and are particularly useful for people without a graphic design background.

  • Many people get good results using Presentation software such as PowerPoint.

  • Canva, Remix, and Easel.ly are just a few examples (Lee, 2022).

  • The following example was created in Canva using an Infographic Template.


Visuals should relate to the point(s) you are making.

  • There are times when a picture really is worth 1000 words. However, remember that the purpose of visuals is to reinforce and augment your message, not to distract from it.

 

Reduce the amount of written text.

  • If you have more text than can be comfortably fit on a page or slide in a reasonable point size, either divide it into a series of slides or convert the information to a handout.

  • If you copy a chart or something similar, increase the size of the image so that it can be clearly seen, especially if you plan on projecting your visual image.

Use a minimum of 18 pt. type. Between 24 and 48 is even better.

  • Look at your visuals from a distance to be sure the information can be clearly seen. For images such as chemical structures, it is crucial that fine details can be seen.

 

Choose fonts carefully. 

  • Sans-serif fonts are often easier to read than serif fonts.

  • Too many different fonts in a slide or a presentation can be distracting, so use no more than two fonts per page, and avoid fonts that are not easily understood such as Baquet Script or Curlz MT.

 

The use of color is helpful.

  • Be judicious in your choice of colors. Too many colors can be distracting.

  • There must be sufficient difference between the background color and the print or image. For example, red type of white background does not provide enough contrast and neither does pale blue on a dark blue background work well.

  • Think carefully about color symbolism, the subjective meaning humans attach to various colors. Try to avoid colors and color combinations that might offend people.

 

Remember the needs of students who are color blind.

  • There are many different types and degrees of colorblindness, instead, they are "color deficiencies" since few people are unable to perceive at least some colors.

  • For some color deficient individuals, the names red, orange, yellow, and green are simply different names for the same color. The same can be true for violet, lavender, purple, and blue.

  • Among the colors most often confused are pink/gray, orange/red, white/green, green/brown, blue green/gray, green/yellow, brown/maroon, and beige/green. Pastels and muted tones are also difficult to distinguish.

 

Do use some white space.

  • A visual or a page that is too crowded can overwhelm, confuse, and discourage the reader.

Making Sense of Complexity: Typologies of Artificial Intelligence

Artificial intelligence (AI) influences many aspects of modern life and has multiple applications. AI is the ability of machines or software to perform tasks that are commonly associated with human intelligence, such as recognizing patterns, making decisions, or learning from data. AI is designed to mimic human capabilities, including pattern recognition, data analysis, and decision-making, and to perform tasks rapidly and efficiently.

 

Algorithms are a set of problem-solving steps computer programs use to accomplish tasks. AI operationalizes the algorithmic steps in smart machines that perform tasks usually associated with human intelligence such as “learning, adapting, synthesizing, self-correction, and use of data for complex processing” (Popenici & Kerr, 2017, para. 3). Machine learning is an application of AI in which large data sets are analyzed, without direct instruction, to detect patterns that might elude human beings. Generative AI is an artificial intelligence technology that can produce various types of content, including text, imagery, audio, and synthetic data.

 

AI originated in the 20th century, but only recently have computers had the computational power to make it practical and useful (Anyoha, 2017). Most people are using AI without recognition because AI powers internet search platforms, predictive text, grammar- and spell-check, GPS, social media curation, smart devices, streaming services, and patient portals. Many people conflate generative AI with large-language models such as those used within ChatGPT, but this is only one type of AI.

 

Typologies of AI

It is essential to recognize that AI is multifaceted and has multiple applications. Therefore, it can be categorized in multiple ways: based on capability, functionality, application, or degree of supervision vs. autonomy.

 

Capability

One capability-based categorization is weak and strong or general AI. Narrow or weak AI can perform single-specific tasks such as making Netflix recommendations, facial recognition, self-driving cars, searching the internet, or translating languages. General or Strong AI can perform tasks in a human-like manner (AVContent Team, 2023). Some descriptions differentiate general AI from strong AI, with the former referring to a computer that is as smart as a human in a general sense and the latter referring to computers that have achieved human consciousness. The latter category is still somewhat theoretical because AI has not yet achieved consciousness or self-awareness. This counteracts the idea that sentient robots will take over the world and enslave humans, as many science fiction novels and films would have people believe. Think of the Terminator or 2001: A Space Odyssey

 


Another capability-based typology characterizes four levels of AI: (a) reactive, (b) limited memory, (c) theory of mind, and (d) self-awareness. Consistent with the weak vs strong typology, this conceptualization indicates that AI has not yet achieved theory of mind, meaning the capacity to understand and remember other entities' emotions and needs and adjust their behavior based on these. This capability is like humans in social interaction” (Arya, 2023, para. 13). Humans develop this capacity as they mature. They also develop self-awareness and emotional intelligence, while AI does not.

Four Levels of AI


Functionality

One functionality categorization scheme asserts three categories of AI: (a) large language models (LLM), (b) learning analytics in which personalized learning is tailored for individuals, and (c) big data, meaning using large data sets to conduct comparative analysis between groups of people. These can be expressed in input and output, instructor and student, or data and functions.

Another functionality schematic suggests the following categories:

·       Analytic AI scans large datasets to identify, interpret, and communicate meaningful patterns of data.

·       Functional AI scans huge amounts of data to take actions.

·       Interactive AI automates communication without compromising on interactivity.

·       Text AI uses semantic search and natural language processing to build semantic maps and recognize synonyms to understand the context of user’s question.

·       Visual AI identifies, recognizes, classifies, and sorts objects or converts images and videos into insights. (Sarker et al., 2022).

Application

Yet another way of categorizing AI is by applications in which it is used. For example, expert systems use information collected from recognized domain experts to facilitate fast decision-making. Natural language processing (NLP) enables AI to use language in a human-like manner in chatbots, language translation, and sentiment analysis, which is used to determine whether the emotional tone of a message is positive, negative, or neutral. Sentiment analysis has become an important business function used to improve customer service, market research, and to monitor brand performance. It can distinguish the positive from the negative of a seemingly contradictory sentence such as: “While I liked this product, I was disappointed with the color.”

Supervision vs. Autonomy

This typology is often used to describe the process of machine learning, in which:

·       Supervised learning—all data are labeled.

·       Semi-supervised—some input data are labeled, while some are not.

·       Unsupervised—all input data are unlabeled (Alloghani et al., 2020).

 

These terms can also be used to describe AI. Examples of supervised processing include virtual assistants such as Siri and Alexa, while an example of unsupervised or autonomous processing is self-driving cars.


You may notice overlaps between the different typologies, as the following concept map clarifies.

No matter how you conceptualize it, the field of AI is complex, growing, and rapidly being integrated into multiple fields of professional practice. These typologies highlight the diverse nature of AI, and the various systems designed for specific purposes and possessing different levels of capabilities. The field of AI continues to advance and new typologies may be developed as its capacities evolve.

President Biden Issues Executive Order to Establish Standards for AI Technologies

 

By Lilian H. Hill

On October 30, 2023, President Biden issued an executive order to establish Artificial Intelligence (AI) safety and security standards, protect Americans’ privacy and security, advance equity and civil rights, and advocate for consumers and workers. It employs broad emergency powers, usually only invoked for urgent situations such as the coronavirus pandemic or war, and the power of multiple government agencies to address the risks of artificial intelligence, which Biden described as the “most consequential technology of our time.” Biden has also called on Congress to create legislation to regulate AI as multiple attempts have failed to pass.

 

Released just days before an international AI Safety Summit held in the UK (Zakrzewski et al., 2023), the 111-page Executive Order has seven focus areas: 

  • safety
  • protection of American’s privacy 
  • preventing bias 
  • supporting consumers, students, and patients 
  • supporting workers 
  • promoting innovation 
  • advancing American leadership abroad

 

Selected details are described for each focus area below.

 

Safety

 

  • AI corporations will be required to conduct safety assessments of their products and submit findings to the federal government before implementing AI technology.
  • Safeguards should be in place to shield Americans from AI-facilitated fraud and deception.
  • Protocols and best practices will be established to detect AI-generated content and validate official content.
  • A sophisticated cybersecurity initiative will be developed to identify and rectify vulnerabilities in critical software.

Protection of Americans Privacy

  • Federal backing for expediting the development and application of privacy-preserving methods will be utilized, incorporating the use of cryptographic tools.
  • Efforts will be made to strengthen the methods by which federal agencies collect and use commercially available information, alongside privacy guidelines to tackle AI-related risks.

Preventing Bias

  • Standards will be formulated to furnish landlords, federal benefits programs, and federal contractors with precise guidelines to prevent AI algorithms from exacerbating discrimination.
  • The Department of Justice and federal civil rights personnel will receive training to address algorithmic discrimination and to adopt best practices for investigating and prosecuting AI-related civil rights violations.
  • Fairness will be encouraged throughout the criminal justice system by outlining best practices for the use of AI in sentencing, parole and probation, pretrial release and detention, risk assessments, surveillance, crime forecasting and predictive policing, and forensic analysis.

Stand Up for Consumers, Students, and Patients

  • The responsible use of AI in healthcare will be promoted, with the Department of Health and Human Services establishing a safety program to receive reports of, and take action against, harms or unsafe healthcare practices involving AI.
  • Efforts will be made to shape AI's potential to revolutionize education by creating resources to support educators deploying AI-driven educational tools, such as personalized tutoring in schools.

Promoting Innovation

  • AI research across the United States will receive support by initiating the National AI Research Resource pilot program, providing AI researchers and students access to vital AI resources and data and increased grants for AI research in critical areas such as healthcare and climate change.
  • An equitable, open, and competitive AI ecosystem will be encouraged by granting small developers and entrepreneurs access to technical aid and resources, assisting small businesses in commercializing AI breakthroughs, and encouraging the Federal Trade Commission to exercise its authority.
  • The opportunities for highly skilled immigrants and nonimmigrants with expertise in crucial fields to study, remain, and work in the United States will be expanded by modernizing and streamlining visa criteria, interviews, and reviews.

Supporting Workers

  • Principles and best practices will be devised to mitigate the negative impacts and maximize the benefits of AI for workers, addressing job displacement, labor standards, workplace equity, health and safety, and data collection.
  • A report will be compiled on AI's potential effects on the labor market, and strategies to bolster federal support for workers facing labor disruptions, including those resulting from AI, will be developed.
  • The opportunities for highly skilled immigrants and nonimmigrants with expertise in crucial fields to study, remain, and work in the United States will be expanded by modernizing and streamlining visa criteria, interviews, and reviews.

Advancing American Leadership Abroad

  • Strengthen bilateral, multilateral, and multi-stakeholder engagements to collaborate on AI with the State Department, in conjunction with the Commerce Department, leading efforts to establish robust international frameworks for harnessing AI's benefits and managing its risks, ensuring safety.
  • Accelerate the development and implementation of crucial AI standards with international partners and in standards organizations, ensuring the technology's safety, security, trustworthiness, and interoperability.
  • Advocate for the safe, responsible, and rights-affirming development and deployment of AI globally to tackle global challenges, such as advancing sustainable development and mitigating threats to critical infrastructure.

Ensuring Responsible and Effective Government Use of AI

  • Issue guidelines for agencies' use of AI, including clear standards to protect rights and safety, improve AI procurement, and strengthen AI deployment.
  • Assist agencies in procuring specified AI products and services more quickly, affordably, and effectively through streamlined contracting processes.
  • Expedite the rapid hiring of AI professionals as part of a government-wide AI talent surge led by the Office of Personnel Management, U.S. Digital Service, U.S. Digital Corps, and Presidential Innovation Fellowship. Agencies will provide AI training for employees at all levels in relevant fields.

 

This Executive Order is far-reaching and comprehensive. It builds on and expands the considerations articulated in the White House Blueprint for an AI Bill of Rights. However, news commentary indicates that the Executive Order is only a first step in regulating rapid AI development and implementation, but also indicates that the Executive Order needs to be improved in enforcement mechanisms.

Digital Health Literacy Access and Skills

 

Image credit: Pexels, Telehealth

By Lilian H. Hill, PhD

Health literacy and digital health literacy are related but distinct ideas. This blog post is part of our series on different forms of literacy in which we provide definitions of health literacy, digital health literacy, and eHealth literacy. 

Health Literacy

To understand digital health literacy, a definition of health literacy is needed. In Healthy People 2030 (2023), the U.S. Department of Health and Human Services (HHS) provided an updated definition of health literacy that has two components: personal health literacy and organizational health literacy:

  • Personal health literacy is the degree to which individuals have the ability to find, understand, and use information and services to inform health-related decisions and actions for themselves and others.
  • Organizational health literacy is the degree to which organizations equitably enable individuals to find, understand, and use information and services to inform health-related decisions and actions for themselves and others. (para. 3)

Begun in 1980 and occurring decennially, the Healthy People initiative sets priority areas to improve population health, provides implementation tools, and tracks progress. This updated definition acknowledges the responsibilities of health providers and systems to communicate effectively with patients of varying identities, language skills, and literacy levels. Older definitions only included reference to personal health literacy skills, burdening patients. 

Digital Health Literacy

Digital health literacy refers to accessing health information online and navigating and using digital or electronic health information and patient resources. It includes electronic patient portals, technology for telehealth visits, and using computers and mobile devices to access medical information and interact with healthcare teams.

The World Health Organization defines electronic health (eHealth) services as the cost-effective and secure use of information communication technologies to support health. Examples include electronic communication between patients and providers, electronic medical records, patient portals, and digital personal health records. A category of eHealth is mobile health (mHealth), including phones, tablets, and computers to use applications (apps), wearable monitoring devices, and texting services. The Centers for Disease Control and Prevention (CDC) defines eHealth literacy as the ability to evaluate health information from electronic sources and apply the knowledge gained to addressing or solving a health problem (CDC).

Digital health literacy involves skills including: 

  • Accessing and using online medical scheduling platforms to make appointments.
  • Using and navigating electronic health records and patient portals.
  • Receiving text message reminders from healthcare providers.
  • Receiving digital health information instead of handouts (for example, information about medication instructions for medication adherence).
  • Obtaining results of medical or diagnostic tests online.
  • Searching for and evaluating online health information. (Rural Health Information Hub, n.d.).
  • Comparing options and enrolling in a health insurance plan on a government website.
  • Searching online for healthy recipes to prepare for a family member with health conditions such as hypertension or diabetes.

Unfortunately, these skills depend on computer and mobile device access, digital tools experience, and a robust broadband network. For example, people with limited income and live in remote rural areas need help accessing broadband. Estimates of people lacking access range between 21 to 162 million (Stauffer et al., 2020). The U.S. government announced investing over 40 billion dollars to extend broadband access to all Americans (The White House, 2023). Access depends on having a data plan with broadband access, yet 40% of low-income households are not subscribed to any data plans. Relying on limited cell phone data or public Wi-Fi spots has limitations, including interruptions and a lack of security and privacy (Sieck, 2021). 

Many healthcare organizations have invested heavily in digital resources to support patient healthcare. Research indicates these tools “can foster greater patient engagement, better support for patients outside of the clinic visit, and can improve health outcomes” (Sieck, 2021, p. 1).

Digital health literacy has become so important to healthcare that it is now included as one of the social determinants of health, the conditions in the environments where people live, learn, work, and play that influence human health, functioning, and quality of life (Sieck et al., 2021). Other elements include: 

  • safe housing, transportation, and neighborhoods;
  • racism, discrimination, and violence;
  • education, job opportunities, and income;
  • access to nutritious foods and physical activity opportunities;
  • polluted air and water; and 
  • language and literacy skills (USHHS, 2023). 

As clinical care delivery is quickly being integrated with digital technologies, Sieck et al. (2021) recommend that healthcare organizations adopt digital inclusive strategies, including assessing patient literacy and access and partnering with community organizations to facilitate digital skills training and connectivity.
