- HI 501Unit 9 Assignment: Older Adult Interface ChallengesStacie AllegerFor this analysis, the term "Older Adult" refers to individuals aged 65 and older, recognizing that this population often experiences age-related changes in vision, cognition, dexterity, and health literacy that directly impact their interaction with technology.May experience slower cognitive processing, reduced memory, vision, and hearing impairments, and decreased dexterity.Often, late adopters of technology may lack confidence using health devices.Emotional responses (e.g., anxiety) are common when interpreting health data without support.
- Skluzavka: 2
- I like being able to check my heart and blood pressure whenever I want... It makes me feel safer.
- HR: 82 bpmDaily movement goal met. Keep up the good work!
- Skluzavka: 3
- Why is my heart rate so high? I just woke up... Am I having another clot?
- HR: 114 bpm
- Should I call 911? Should I call my daughter? Or maybe I should wait... I don't know.
- HCI PROBLEM: It's 2:18 a.m. Mrs. Jenkins was startled awake and decided to check her heart rate. The number on the screen worries her, even though she has no other symptoms. The device provides no context or recommendations. It only shows raw data. Without clinical insight or support, she’s left unsure and anxious.Borycki (2019) notes that technology-induced anxiety is often caused by poor interface design and lack of guidance, which can lead to unnecessary worry or error.
- Skluzavka: 4
- It would help if the device told me what to do next...
- HR: 114 bpm
- Maybe I should just call 911... but what if it’s nothing? I don’t want to overreact.
- Mrs. Jenkins is uncertain and anxious. She’s receiving data but not direction. There's no contextual support. She only sees a number. Human-computer interaction (HCI) should reduce cognitive burden, especially in vulnerable moments. Instead, it’s adding to her stress. This lack of guidance represents a breakdown in human-computer interaction, particularly problematic for elderly users without clinical training (Borycki, 2019).
- Skluzavka: 5
- It says 114... Should I call someone? I don’t feel sick, but what if something’s wrong?
- HR: 114 bpm
- Okay... I feel better having someone here.
- You’re not having any symptoms, right? Let’s rest a bit and recheck in 30 minutes. If it’s still high or you are having symptoms, we’ll call the doctor
- Skluzavka: 6
- It says 76 now. That looks better, doesn’t it?
- HR: 86 bpm
- I’m glad I waited. I almost panicked for nothing.
- Yes, that’s a normal heart rate. No symptoms and a good number. Nothing to worry about.
- Thirty minutes of rest made a clear difference. With calm reassurance and time to recheck, she avoided an unnecessary ER visit.HCI tools that offer guidance for when to act or when to wait, can reduce anxiety and empower older users to make safer, more confident decisions.

- This is Mrs. Jenkins. She’s 78, lives alone and manages her health with a few smart devices. After a pulmonary embolism a few years ago, her family helped set her up with an Apple Watch, smart scale, blood pressure monitor, and a portable EKG. Her daughter is currently visiting from out of town.Technology helps Mrs. Jenkins stay independent, but without clinical guidance, she often navigates these tools on her own.
- I’ve noticed my blood pressure and heart rate have been creeping up this week.
- BP and HR trending upward over 5 days.-Notice sent to provider
- Thanks for sharing your logs. It looks like the new medication isn’t working as expected. I’ll adjust your prescription today
- In this case, her devices captured a pattern over time (not a single alarming number). The data was shared with her provider and reviewed in a scheduled telehealth visit.When IoT is paired with clinical oversight and well-integrated data sharing, it enables proactive, informed care. This is where HCI succeeds and is consistent with Borycki’s (2019) vision for safe and integrated digital health ecosystems.
- Skluzavka: 8
- HR: 108 bpm – Slightly elevatedNo symptoms reported. Suggest: Rest and recheck in 30 minutes.Call provider if recurrent or accompanied with other symptoms.Tap to learn more.
- What does that even mean? Should I worry?
- HR: 114 bpm
- Okay. I don't have other symptoms. It’s not urgent. I’ll check again later.
- Simple, age-friendly changes such as adding plain-language prompts, color coding, and symptom-based guidance can reduce fear and support safer decisions. HCI must be designed for real-world users, especially older adults who often rely on these tools alone.Rigby et al. (2016) and Rosan et al. (2008) both advocate for simulation-based testing and interface redesign tailored to real-world user behavior.
- Skluzavka: 9
- HR: 78 bpm – Within normal range.No action needed.
- That’s better. I understand what it means now.
- With clear, supportive design, Mrs. Jenkins feels more confident managing her health without unnecessary worry or overreaction.As Borycki (2019) explains, improved HCI empowers users by translating raw data into meaningful insight, promoting independence, peace of mind, and better outcomes.
- Skluzavka: 10
- Human support fills the gap that the device’s design failed to address. A simple conversation replaces uncertainty with calm.With better HCI design, like prompts to rest, recheck, or contact a provider. Technology could offer that same reassurance when no one else is there.
