A Qualitative Examination of a Reminiscence Intervention for Older Adults Using Three-Dimensional (3D) Printed Objects.

Reminiscence has been found to be an effective therapy for older adults and researchers and practitioners have identified a range of benefits, from cognitive stimulation to the reconciliation of past experiences. In this qualitative study, the authors explore the experiences of older adults engaged in a technology-enhanced form of reminiscence therapy (RT) using three-dimensional (3D) printed objects from peoples' past. Content analysis of individual interviews with seven participants ( = 7) revealed three themes: (1) positive experiences with the RT intervention; (2) reflections on the use of 3D printed objects; and (3) the development of relationships between participants and researchers.

Perceptual grouping effects on cursor movement expectations.

Objective: Two studies were conducted to develop an understanding of factors that drive user expectations when navigating between discrete elements on a display via a limited degree-of-freedom cursor control device.

Background: For the Orion Crew Exploration Vehicle spacecraft, a free-floating cursor with a graphical user interface (GUI) would require an unachievable level of accuracy due to expected acceleration and vibration conditions during dynamic phases of flight. Therefore, Orion program proposed using a "caged" cursor to "jump" from one controllable element (node) on the GUI to another.
