This article discusses recent developments in the authors' experiments using Google's Soli alpha kit to develop a non-invasive blood glucose detection system. The Soli system (co-developed by Google and Infineon) is a 60 GHz mm-wave radar that promises a small, mobile, and wearable platform intended for gesture recognition. They have retrofitted the setup for the system and their experiments outline a proof-of-concept prototype to detect changes of the dielectric properties of solutions with different levels of glucose and distinguish between different concentrations. Preliminary results indicated that mm-waves are suitable for glucose detection among biological mediums at concentrations similar to blood glucose concentrations of diabetic patients. The authors discuss improving the repeatability and scalability of the system, other systems of glucose detection, and potential user constraints of implementation.

Visual hand gesture interaction is one of the main ways of human-computer interaction, and provides users more interactive degrees of freedom and more realistic interactive experience. Authors present a hybrid model based on SVM-LSTM, and design a three-dimensional dynamic gesture interaction system. The system uses Leap Motion to capture gesture information, combined with SVM powerful static gesture classification ability and LSTM powerful variable-length time series gesture processing ability, enabling real-time recognition of user gestures. The gesture interaction method can automatically define the start and end of gestures, recognition accuracy reached 96.4%, greatly reducing the cost of learning. Experiments have shown that the gesture interaction method proposed by authors is effective. In the simulated mobile environment, the average gesture prediction only takes 0.15 seconds, and ordinary users can quickly grasp this method.

Being in nature is often regarded to be calming, relaxing and purifying. While technology has the potential to support engagement with nature, developing systems that provide support in an unobtrusive manner holds many challenges for interaction design. In this article, the authors describe their reflections around the NatureCHI workshop series. The aim with the workshops has been to help foster a research community interested in the design of Unobtrusive User Experiences with Technology in Nature. The first of two workshops ran as part of CHI 2016 in San Jose, California, while the second workshop took place alongside MobileHCI 2017 in Vienna, Austria. With 25 papers presented in total, the workshops demonstrate a rising interest in the areas where nature and interactive technologies meet.

Collaboration is a core component of work activities amongst flight attendants. This is as they work to promote onboard safety and deliver a high level of customer service. Yet we know little of how flight attendants collaborate and how we can best design technology to support this collaboration. Through an interview study with flight attendants, the authors explored their collaborative practices and processes and how technology aided such practices. While technologies like interphones and flight attendant call buttons act as collaboration tools, they identified instances where the usability and functionality of these devices were barriers for maintaining efficient communication, situation awareness, and information exchange. The authors used these results to identify design suggestions for technology that can enhance communication and collaboration in aircraft settings amongst flight attendants. To illustrate these design suggestions, they designed and developed Smart Crew, a smartwatch application that allows flight attendants to maintain an awareness of each other and communicate through messaging with haptic feedback. Smart Crew is designed with an emphasis on real time information access, location updates and direct communication between flight attendants regardless of their location on the airplane.

As the digital generations have grown up with high-tech gadgets and become avid users of mobile phones and apps, they are also exposed to increasing mobile security threats and vulnerability. In this paper the authors discuss the impact of recent mobile technology advancements on mobile threat environment and mobile security practices. They also conducted a survey to 262 college students to examine their mobile phone usage patterns, security concerns and practices. The results show that students use their mobile phone frequently for various productivity and entertainment purposes. They are generally aware of and concerned about mobile security, not only on losing the phone physically but also on data theft, web threat, and mobile malware. Students also practice security to some extend - most change PIN and passwords regularly, download their apps mostly from official app stores, and generally keep their OS and apps up-to-date. The authors also found significant correlations between mobile security practices and personal attributes, including major, gender, and technology aptitude.
