One-Handed Interaction Technique for Single-Touch Gesture Input on Large Smartphones

Mixed Reality (MR) is the next evolution of humans interacting with computer as MR can combine the physical environment and digital environment and making them coexist with each other [1]. Interaction is still a valid research area in MR, and this paper focuses on interaction rather than other research areas such as tracking, calibration, and display [2] because the current interaction technique still not intuitive enough to let the user interact with the computer. This paper explores the user interaction using gesture and speech interaction for 3D object manipulation in mixed reality environment. The paper explains the design stage that involves interaction using gesture and speech inputs to enhance user experience in MR workspace. After acquiring gesture input and speech commands, MR prototype is proposed to integrate the interaction technique using gesture and speech. The paper concludes with results and discussion.

Scavenging Rates

In this study, the pomegranate seeds were treated by micro-cutting assisted interaction technique. The effective components were extracted from pomegranate seeds with 95% ethanol at room temperature, and their antioxidant capacity in vitro was determined. The results showed that the scavenging rates of DPPH radical, superoxide anion radical, hydroxyl radical and lipid peroxidation were 70.97, 51.95, 52.85, and 80.62%, respectively. The antioxidation ability of alcohol extract of pomegranate seed was studied in order to provide theoretical basis for developing more value of pomegranate seed in the future.
