Keyboard Layout

Usability and typing performance on a smartphone with two unique QWERTY keyboard layouts (standard vs. curved) on two phone sizes (4.0-inch vs. 5.5-inch displays) was investigated in this study. The effect of hand posture was also investigated (one- vs. two-thumbs). Results show users typed the slowest when using one thumb with the curved keyboard on the small phone (15 WPM), and the fastest when using two thumbs with the standard keyboard on the large phone (24 WPM). Typing performance with the curved keyboard on the large phone size (19 WPM) did not differ between typing with one thumb using the standard keyboard on the large or small phone, or with two thumbs using the standard keyboard on the small phone. Error rates were higher when using the curved keyboard, regardless of phone size. Subjectively, the curved keyboard was rated inferior for both phone sizes in comparison to the standard layout.

Two Stages

Background and Objectives: The aim of the study was to assess the factors that influence the occurrence of concerns and their intensification after the implantation of a cardioverter defibrillator. Materials and Methods: This was a prospective and observational study including 158 patients. The study was conducted in two stages: stage I before implantable cardioverter defibrillator (ICD) implantation and stage II follow-up visit six months after ICD implantation. Standardized questionnaires were used in both stages. Results: Age and female gender were significantly correlated with the occurrence and intensity of concerns. Patients who had a device implanted for secondary prevention also experienced higher levels of concern. Additionally, a multiple regression model using the stepwise input method was performed. The model was statistically significant and explained 42% of the observed variance in the dependent variable (p = 0.0001, R2 = 0.4215). The analysis showed that age (p = 0.0036), insomnia (p = 0.0276), anxiety (p = 0.0000) and negative emotions (p = 0.0374) were important predictors of the dependent variable and enabled higher levels of the number of concerns to be predicted. Conclusions: There is a relationship between the severity of the concerns related to an implanted ICD and age, gender, anxiety, negative emotions and insomnia. Indications for ICD implantation may be associated with increased concerns about ICD.
