“…The applications are particularly useful in making precise calculations (e.g., the angles for the PTSOT test). One of the advantages of using software tools is that the process of data analysis is facilitated [50]. In a paper-based approach, the data must be digitized for analysis, which can be time consuming depending on the amount of data to be digitized.…”

SLAM-based augmented reality for the assessment of short-term spatial memory. A comparative study of visual versus tactile stimuli

The assessment of human spatial short-term memory has mainly been performed using visual stimuli and less frequently using auditory stimuli. This paper presents a framework for the development of SLAM-based Augmented Reality applications for the assessment of spatial memory. An AR mobile application was developed for this type of assessment involving visual and tactile stimuli by using our framework. The task to be carried out with the AR application is divided into two phases: 1) a learning phase, in which participants physically walk around a room and have to remember the location of simple geometrical shapes; and 2) an evaluation phase, in which the participants are asked to recall the location of the shapes. A study for comparing the performance outcomes using visual and tactile stimuli was carried out. Fifty-three participants performed the task using the two conditions (Tactile vs Visual), but with more than two months of difference (within-subject design). The number of shapes placed correctly was similar for both conditions. However, the group that used the tactile stimulus spent significantly more time completing the task and required significantly more attempts. The performance outcomes were independent of gender. Some significant correlations among variables related to the performance outcomes and other tests were found. The following significant correlations among variables related to the performance outcomes using visual stimuli and the participants’ subjective variables were also found: 1) the greater the number of correctly placed shapes, the greater the perceived competence; 2) the more attempts required, the less the perceived competence. We also found that perceived enjoyment was higher when a higher sense of presence was induced. Our results suggest that tactile stimuli are valid stimuli to exploit for the assessment of the ability to memorize spatial-tactile associations, but that the ability to memorize spatial-visual associations is dominant. Our results also show that gender does not affect these types of memory tasks.

“…Furthermore, they also reported that older participants enjoyed the paper-based design sessions. A more recent study (Heintz et al, 2018) compared paper-based and tool-based prototypes to provide feedback on e-learning prototypes. Although this study was conducted among working adults (science teachers from different European countries), it found that the paper-based approach was able to generate more feedback.…”

This study offers insights, gathered from co-design activities with older adults, on the design of e-commerce websites. Twenty older adults (aged 52–75 years) took part in a paper-based design activity in which they were presented with a web browser window, cutouts of a selection of web objects (e.g., product images and “add to cart” buttons) in a range of designs, and office stationery for making annotations and asked to select and place web objects onto the browser window to express their design ideas for two types of shopping experience: purchasing a grocery item that is inexpensive and typically purchased in multiples (carrots) and purchasing an assistive technology item which is considered expensive and normally purchased as a one-off (wheelchair). Objects selected frequently by the older adults for inclusion in both types of e-commerce websites included product images, price, and an “add to cart” button. Some objects were selected for inclusion depending on the type of website—quantity selection was selected for the cheap, multiple purchase item, whereas descriptions, reviews, and shipping/return information were deemed important only for the expensive, single-item purchase. Regarding the relative placement of the “add to cart” button, participants most often placed the button close to the quantity selection and/or the price. Furthermore, participants expressed that having these three elements presented within a visually distinctive “buy box” would be beneficial. This study offers insight into which website elements are deemed important by this older adult participant group for e-commerce websites and how the elements should be arranged, and the results also indicate that some design requirements may differ between different types of shopping experience. The findings can potentially benefit designers, developers, and industries to more fully grasp the potential of usable online shopping applications.
