The Psychological Impact of Digital Notifications
- Receiving a text message stating "we need to talk" often triggers immediate anxiety, uncertainty, and a sense of being in trouble, regardless of the sender's identity. 0s
- The specific sound of a notification can induce feelings of dread, irritation, or being startled, which suggests that the design of these alerts does not align with the actual importance of the required action. 35s
- Notifications create an "attentional cost," which is the emotional energy and time required to shift focus from a current task to the alert, even if the content of the notification is not immediately reviewed. 1m35s
- "Attentional residue," a term coined by Dr. Sophie Leroy in a 2009 study, describes the phenomenon where mental focus does not immediately return to the original task after being interrupted by a notification. 1m55s
- The cumulative effect of attentional cost and residue over time contributes to feelings of being overwhelmed and a perceived lack of productivity. 2m25s
Evolution of Physical and Mental Ergonomics
- Physical ergonomics originated during the agricultural and industrial eras with the goal of making work more comfortable and productive, such as designing handles that are easier to grip. 3m5s
- Ergonomic principles are applied to office environments through the design of chairs, desks, and screens to ensure workers can remain seated for long periods with minimal discomfort. 3m35s
- Design principles can be intentionally used to create discomfort, as evidenced by expensive chairs in public spaces like the Harvard Art Museum Cafe that are designed to be comfortable for only short durations. 4m5s
- Physical ergonomics is exemplified by chairs designed to signal when a person should leave a space, such as in a museum, by making the user uncomfortable 0s.
- Mental ergonomics emerged as work transitioned from industrial and agricultural sectors to the information age, focusing on the design of visual systems, posters, billboards, and information 25s.
Design Techniques for Directing Attention
- Visual systems are designed to direct human attention in specific sequences, often using techniques that trick the viewer into following a predetermined path 35s.
- Data collection methods, including tracking clicks, mouse trails, and eye movements, are used to optimize applications to influence user behavior, similar to a magician’s card trick 55s.
- Interaction designers are increasingly focused on how elements like sound and motion, such as Slack notifications, impact user experience 1m13s.
- The "dot dot dot" typing indicator on mobile devices is an intentionally designed interaction that frequently triggers feelings of anxiety in users 1m25s.
Challenges of the Everything Device
- Emotional ergonomics is defined as the design of attention to ensure it fits the intention behind an experience, rather than simply categorizing experiences as good or bad 1m55s.
- A significant challenge in modern design is that a wide variety of messages—ranging from spam and advertisements to important personal communications—are all funneled through a single device, the phone, without clear emotional separation 2m15s.
- While the "everything device" offers convenience through personalized recommendations for music and media, this convenience comes at the cost of how users spend their time and attention 2m38s.
- The pop-up ad, which functions as an attentional tax, was allegedly created by accident by Ethan Zuckerman while he was attempting to separate ad content from the primary content being read 2m55s.
- The history of design contains many examples of well-intentioned creations that resulted in unintended negative consequences 3m15s.
Historical and Modern Methods of Interaction
- Elevators designed without buttons, which were popularized during the COVID-19 era to minimize physical contact, can inadvertently reduce social interaction by preventing neighbors from engaging in common courtesies like holding the door or offering assistance 0s.
- Traditional door knockers found in the Middle East demonstrate a historical method of emotional ergonomics by using different sounds to identify visitors, allowing residents to prepare appropriately before answering the door 1m15s.
- Modern technology, such as the Ring doorbell, preserves the functional intent of traditional door knockers by providing information about who is at the door 1m48s.
Core Elements of Emotional Ergonomics
- Designing for emotional ergonomics involves balancing convenience with the protection of human attention through three core elements: context, path, and pacing 2m2s.
- Context refers to the clarity of information; for example, vague statements like "We need to talk" create anxiety, whereas adding specific details about the urgency and topic of the conversation provides necessary clarity and relief 2m25s.
- While clarity is often preferred, ambiguity can be beneficial in certain social contexts, such as the intentional surprise of a birthday party 3m5s.
Predictability and Path in User Experience
- Path refers to the predictability of an experience; while QR codes offer versatile access to digital spaces, they can create uncertainty because users may not know the destination of the link 3m25s.
- In high-stakes processes like applying for visas, college admissions, or filing taxes, predictability is essential, and tools like progress bars are effective for managing user expectations 3m55s.
- Providing a clear sense of resolution, such as a notification confirming that a task is fully completed, is a critical component of a positive user experience 4m25s.
Pacing and the Perception of Time
- Pacing serves as a mechanism for understanding the speed at which one moves through a process, complementing the roles of context and path in decision-making 0s.
- Progress bars can influence the perception of time, making waiting periods feel shorter even when the actual duration of a task remains constant 15s.
- Visual interfaces that track progress help make abstract concepts like time tangible, allowing individuals to anticipate future events and make informed decisions 35s.
- Ergonomics involves achieving a proper fit, which does not always necessitate increasing speed 55s.
- In financial transactions, interfaces may intentionally move slower than the actual processing time to foster a sense of trustworthiness and ensure the duration feels appropriate 1m0s.
Contextual Waiting and Emotional Ergonomics
- The perception of time while waiting in a line can shift between urgent and relaxed depending on the context of the situation 1m15s.
- Urgent waiting occurs when there is a desire for a process to conclude as quickly as possible, such as waiting for a bathroom 1m25s.
- Relaxed waiting occurs when the experience itself is valued, such as waiting in line for ice cream or during a social encounter like a first date or meeting a relative 1m35s.
Reframing Design for Human Experience
- Traditional ergonomics focuses on optimizing for productivity, safety, and efficiency 2m5s.
- Emotional ergonomics considers the broader spectrum of human experience, acknowledging that some moments—such as surprise parties or personal milestones—are better served by feeling relaxed or surprising rather than purely productive 2m15s.
- Individuals are encouraged to observe how physical objects and designed experiences shape their bodily comfort and emotional state 2m35s.
- Emotional weight encompasses the impact of designed environments on the nervous system, attention, and the intangible aspects of the human experience 2m50s.
