Hidden costs: COVID-19’s disproportionate impact on underrepresented groups in online computing education.

The goal of the current study was to test a scoring matrix for evaluating and quantifying the difficulty of use of consumer packaging for an older adult population. Scores range from 0 to 100; the lower the score, the less usable the packaging design. Twelve older adults (9 females, 3 males; Mage = 69.5) completed an online survey in which they evaluated 15 everyday packaging types on frequency of use and difficulty of the functional tasks required for use (e.g., pick up and carry, remove seal, open, dispense, close). Blister packaging scored the lowest (M = 71.5) and could benefit the most from redesign. Microwave meal packaging scored the highest (M = 85.8), but this was the only score computed without all participants; only five participants reported using microwave meals. Pull tab cans scored second highest with a mean score of 84.2. In this pilot study, we are laying the groundwork for creating a tool to systematically evaluate and quantify the usability of all packaging types.

Developing a Scoring Matrix to Evaluate the Usability of Consumer Packaging: A Pilot Study

The percentage of older adults using social media has increased substantially in recent years, yet little research has been done to understand the foundations underlying social media technology usage by older adults. Such an understanding is useful for developing intelligent user modeling and personalization techniques specific to this growing community. The current work first compared characteristics of Facebook users to non-users among adults age 51 to 91 and found that older adult Face-book users were significantly more satisfied with their current social roles than non-users. Second, we explored several characteristics of active older adult Facebook users, providing detailed data regarding the ways in which they access social media, the kinds of personal information they typically share, and information about their public versus private communication practices, preferences, and concerns. Finally, we examined specific relationships between older adults’ Facebook communication habits and their attitudes regarding perceived loneliness and social role satisfaction. Controlling for factors such as age, gender, ethnicity, socioeconomic status (education and income), and marital status, we found that directed communications (as opposed to broadcast communications or passive consumption of content) was correlated with reduced loneliness as well as increased social role satisfaction among this distinct population.
