Background: Falls are the main cause of death and injury for older adults in the UK. Many of these falls occur within the home as a result of extrinsic falls risk factors such as poor lighting, loose/uneven flooring, and clutter. Falls education plays an important role in self-management education about extrinsic hazards and is typically delivered via information leaflets, falls apps, and educational booklets. Serious games have the potential of delivering an engaging and informative alternative to traditional methods but almost exclusively, these are currently delivered as exergaming applications that focus solely on intrinsic falls risk factors. This study presents 'Falls Sensei' a first-person 3D exploration game that aims to educate older adults about extrinsic falls risk factors within the home environment. After presenting Falls Sensei, game usability and older adults' perceptions and attitudes towards using the game in practice are explored. Methods: This study involved 15 community dwelling older adults. After playing the Falls Sensei game, participants completed a Systems Usability Scale (SUS) questionnaire and post task interview, and follow-up interviews three weeks later. Inductive and deductive thematic template analysis, informed by the Unified Theory of Acceptance and Use of Technology model, was used to analyse the think-aloud, post-task and follow-up interview transcripts. Descriptive statistical analysis and one-sampled t-tests were used to analyse log-file data and SUS responses. Results: Three high-level themes emerged from the analysis of transcriptions: Performance Expectancy; Effort Expectancy; Social Influence. The SUS score was 77.5/100 which indicates 'Good' levels of usability. Interestingly, reported usability of the game increased with participant age. Participants were positive about the usability of the game (p < = 0.05 for 9/10 items). The most memorable fall hazards were those most commonly encountered in the game or those most challenging to participants. Conclusions: The results support the use of serious games as an engaging tool for educating older adults about extrinsic falls risk factors. Awareness of home hazard detection was raised by the game, and some older adults became more aware for the need to adapt their own homes after gameplay. Further research would be needed to draw comparisons with established interventions.

“…Over time researchers agreed and countered one another's findings, although most prior research has demonstrated that font choice and features affect the participants' preferences [20][21][22]. Conversely, the authors of this study [23] contradict. Font choice has been observed to affect the reading speed in some studies [20,21], though some have not [22,[24][25][26].…”

Usability evaluation is a basic tool for investigating a system's performance in different environments. Many studies found a positive influence of different user interface aesthetics and their organization on usability ratings. These design aspects are one of the most important characteristics of systems usability, and few empirical studies have been examining the importance of typography specifically for safety-critical systems. This study aimed to investigate how different typographic factors, i.e., typeface and fontcase, influence a user's performance in health care safety-critical systems. Different study variables were considered, including task completion time, reflection time, and the total number of touches. To test the study objectives, the Hamilton-c6 ventilator prototype was developed. The experiments were conducted on 15 participants, including male and female physicians, in a controlled environment from different healthcare venues. A well-known technique, one-way ANOVA, was used to assess the data. The results suggest a significant difference between serif (times new roman) and sans serif (Calibri) groups for task completion time; in addition to that, the difference between fontcase groups (sentence case, lowercase, and uppercase) was not statistically significant. Moreover, this study investigated the pairwise influence of different typeface and fontcase groups. The results show a significant difference in task completion time. The descriptive analysis of different groups shows that the times new roman with the upper case group has the lowest task completion time while the Calibri with the uppercase groups have the highest task completion time. This study may pave a good research direction to explore the impact of these and other aesthetic factors in multiple contexts.

“…This effect is also found in (Beymer, Russell, and Orton 2005) research on the effect of line length on reading.On the other hand, Beymer et al research result however indicates that, although the small font is reducing the sweeping time. It is however increasing the fixation time compared to a larger font size.Based on (Bernard et al, 2002), (Bhatia, Samal, Rajan, and Kiviniemi, 2011), and (Ivory, and Hearst, 2002) researches, they indicated that font size at least 12 pt is the best suited for the web page. Table 2 below summarizes the studies that have been conducted on font size.…”

Effects of Video Display Terminal Resolutions to the Legibility of Text on a Web Page

Higher Video Display Terminal (VDT) resolutions have been proven to provide better quality in improving image quality displayed. The higher the resolution means more pixels per-inch-square available to display an image. This increase, however, may not be to the fonts used on web pages for improved legibility. Legibility of web text has been proved essential to ensure the quality of a web page. Support by the evidence from the previous research experiment results; low level of web text legibility can cause various visual related problems and usability of a web page. This research will focus on finding possible improvement effects on VDT resolution that might need to be considered in designing the web text. In this research 6 font types and two VDT resolutions for low and high have been selected. Approximately 200 subjects were randomly selected for this experiment. The selected subjects were divided into two groups for low and high resolution. Selected subjects performed legibility test and subjective preference test experiments on 6 selected type of fonts. Overall findings indicate that there is an improvement but no significant difference between the two VDT resolutions.Keywords:Legibility; Web text; Video Display Terminal; Fonts; Resolutions. INTRODUCTIONOne of the segments usually found on a webpage is the main content. The main content usually contains a series of text that will be the main focus of the user visits the web page. Backed by previous researches that are done by (Duckett, 2002) on readers reading strategy and (Nielsen and Pernice, 2010) on their eye tracking studies. Users actually scan web pages for relevant content related to the information they are looking for and not the whole content.On separate studies did by (Nielsen, 2008), on average, users actually only read about 20% of the whole text.Based on this evidence of how user's reading behaviour and how little actually user read the web text, the quality of a web text is crucial and needs to be taken care seriously. There are two main factors influencing the quality of web text; the quality of information presented (the content), and the quality of presentations. On the quality of presentation, one of the main factors is the legibility of the web text. Legibility is defined as "the quality of being clear enough to read" from the Oxford Dictionaries.On web text design, besides the colour combination used on the web text and the background, based on previous research, certain type and size of fonts does have a significant advantage in terms of legibility performance.This research however will explore even further, by studying the effects or the improvement on web text legibility that might improve when using much higher VDT resolution setting. The higher the VDT resolution the more density the pixel is. These higher pixel densities have proved to increase the quality of an image displayed but unproven that it might also increase the legibility of web text. Due to this unanswered question, this research will first explored the research...
