A touchless interaction interface for observing medical imaging
摘要： Using volume rendering to generate 3D models is associated with the problem of missing features on areas of interest, which are possibly concealed by other information. This article presents a novel focus-and-context medical imaging observation system using gesture-based technique to build a touchless interactive environment. The system offers two types of medical imaging observation tool, namely, 3D section cutting tool and 3-axes cross-section synchronization tool, enabling users to quickly and easily observe tissue sections. Feature classification was achieved using region growing and size-based transfer approaches. Combined with view penetration function (cylinder and cone view penetration functions), the system allows for direct observation of hidden features. The analytical experimental results verified that the proposed system is easy to operate in a touchless environment and creates positive user experience regarding observation and interaction.

Touchless Mechanism to Detect Rhodamine B Concentration in Distilled Water Using Fiber Bundle
摘要： Detection of rhodamine B concentration in distilled water can be conducted without direct contact between the sensor probe and the sample using fiber bundle as a sensor probe and concave mirror as a sample container. The fiber bundle used is a concentric and a pair bundle probe. The working mechanism of the sensor is based on the displacement sensor and absorption of rhodamine B on laser light at a wavelength of 543 nm. The concentration of rhodamine B was detected through the valley and the peak voltage resulting from the displacement of the sensor probe to the sample surface. The best performance is shown by a sensor that uses a concentric bundle as a probe with a detection range of 0–20 ppm with a resolution of 0.6 ppm.
