CHECKLOCK: Smart Door Lock for ADHD Users

Individual Project | 2 Month
2024

Overview

For individuals with ADHD, executive function deficits often lead to forgetfulness and heightened stress, particularly when leaving home. The CHECKLOCK project addresses this issue by proposing an innovative smart door lock. Equipped with a personalised checklist displayed on a touchscreen, CHECKLOCK supports users at the critical moment before leaving, promoting independence and reducing anxiety.

Problem Statement

ADHD-related challenges, such as nonverbal working memory deficits and inhibitory control issues, significantly impact daily life. Forgetting personal items is a common problem that can lead to stress, social embarrassment, and practical inconveniences. Despite existing tools, there is a lack of immediate and intuitive solutions tailored to these specific needs.

Proposal

CHECKLOCK integrates technology and human-centered design to empower users with ADHD:

Touchscreen-Enabled Smart Lock: Displays a personalized checklist when the door handle is engaged.
AI and Adaptive Learning: Customizes reminders based on user habits.
Sustainable Design: Uses recycled materials and energy-efficient technology.

By addressing cognitive load and fostering self-efficacy, CHECKLOCK enhances daily routines and overall well-being.

● Research Insights

Literature Review:

ADHD impacts nonverbal working memory, planning, problem-solving, and emotional regulation (Barkley, 2010).
Individuals with ADHD report higher levels of forgetfulness and attentional issues (Salomone et al., 2020).
Memory inhibition deficits exacerbate daily frustrations (Storm & White, 2010).

User Interviews:

Conducted structured interviews with 12 individuals aged 16–25 with ADHD.
Key Findings:
- 75% reported frequent forgetfulness, often leading to stress and embarrassment.
- Forgetfulness increased cognitive load and negatively impacted self-esteem.
- Users expressed a desire for simple, non-intrusive solutions to support memory.

Research Questions:

How to develop a checklist for managing daily tasks more effectively, promoting independence and reducing anxiety among ADHD people?
How can touchscreen interfaces be optimised to enhance cognitive recall and ease of use for individuals with executive function deficits?
