This image was created as Table of Contents (TOC) figures for the article "Measuring Physical Activity in Older Adults through Data Donation: Consent Rates, Donation Success, & Bias" published in Journal of Medical Internet Research (JMIR). 

The image was generated with DALL-E (AI text-to-image model) in photorealistic style, then cropped and adjusted to 1000x750 pixels (4:3 aspect ratio) to meet JMIR TOC requirements. Minor graphical edits were made to align icons (heart, shoe, cloud) with the smartphone to visually represent the concept of data donation.
