Along with the development of technology, the launching of new devices often leaves the usability problems for the elderly behind. It happens not only for devices but also its application, i.e., entertainment applications, health applications, learning applications, etc. Most of the time, the elderly find it hard to use due to its usability problems or unfamiliar feelings. This research focused on empirically investigating a health application interface so that elderly could use it easily without obstacles and help the treatment independently. Three interface modalities were tested, namely, textual, pictorial, and typing interfaces. The result showed that the option-based interfaces (i.e., textual and pictorial) led to shorter performance time than input-based interface (i.e., typing) among the three interfaces. Also, the pictorial interface has the highest SUS score. All respondents chose the pictorial interface as their first choice, enabling health application accessibility through the appropriate interface modality for the elderly.

The purpose of this study was to investigate the effects of clothing fit and material of Islamic sportswear for female on physiological responses and body heat balance during exercise in warm and humid environment. Twelve healthy female students (20.3±0.4 years) exercised wearing four types of women’s Islamic sportswear comprised of two level of clothing fit: loose-fit and tight-fit, and two types of material for sportswear: cotton and polyester on four separate occasions, and in random order. They performed a 30-min treadmill exercise at an intensity of 70% HRmax and then rested on a chair for 20 min for recovery in a chamber set at an ambient temperature of 34°C and relative humidity of 80%. The results showed that clothing fit did not significantly affect physiological and subjective responses, but clothing material did; sportswear made of cotton resulted in a higher increase of tympanic temperature during exercise and recovery compared to that made of polyester (P
