Toward a new age of patient centricity? The application of eye-tracking to the development of connected self-injection systems
摘要： Background: Increasing interest in digitally enhanced drug delivery tools urges industry and academia to rethink current approaches to product usability. This article introduces mobile eye-tracking, generating detailed contextual data about user engagement with connected self-injection systems as a new methodological approach to formative usability assessment. Methods: A longitudinal case study with a total of 35 injection-na?ve participants was conducted. In three consecutive experiments, eye-tracking was applied to formative usability testing of a novel connected self-injection device. Three eye-tracking derived usability indicators were established to assess product effectiveness, efficiency, and ease of use. Results: Analysis of the data revealed events of user hesitation, process interruption and unintended action, and these occurrences could either be completely eliminated or significantly reduced throughout the process. At the same time, the overall use duration decreased from 86.1 to 58.7 sec. Analysis revealed that product modifications successfully guided user attention to those interface elements most relevant during each task, thereby improving product ease-of-use. Conclusions: The step-wise improvement in the usability indicators demonstrates that iteratively applying eye-tracking methods effectively supports the user-centered design of connected self-injection systems. The results highlight how eye-tracking can be employed to gain an in-depth understanding of patient engagement with novel healthcare technologies.

[IEEE 2019 IEEE 46th Photovoltaic Specialists Conference (PVSC) - Chicago, IL, USA (2019.6.16-2019.6.21)] 2019 IEEE 46th Photovoltaic Specialists Conference (PVSC) - Fight Climate Change (Global Warming) With Solar + Multi-Storage Resilient Smart Home/Building And Ensure Security & Safety While Saving Thousands
摘要： Using industrial IoT smart devices for home/building automation, energy usage monitoring & control and sky-camera with local satellite/radar imaging for weather forecasting we achieved a smart energy management system that can control and balance the home/building energy ecosystem and reduce the carbon footprint by 92%. Grid-buy electricity from the utility was reduced from 14.5MWh/year costing $4,754/year to 1.2MWh/year costing $371/year for a return on investment of <3.1 years. Using multiple renewable energy storage techniques (battery, hot and cold thermal storage) we reduced the overnight energy usage from 70% to 25% which was satisfied by battery and thermal storage device discharge. We achieved Island Nano-Grid and 100% renewable clean energy for resilience, security, safety and savings.

[IEEE 2019 SBFoton International Optics and Photonics Conference (SBFoton IOPC) - Sao Paulo, Brazil (2019.10.7-2019.10.9)] 2019 SBFoton International Optics and Photonics Conference (SBFoton IOPC) - Using the Smartphone as an Ubiquitous Platform for Implementing Optical Fiber Sensors
摘要： This paper reports the development of a low-cost kit to turn smartphones into versatile platforms for interrogating optical fiber sensors. The adapter for connecting the fiber to the phone camera was 3D printed, whereas the application software was programmed for AndroidTM operating system. Different types of sensors based on multimode fiber and LED source were tested. The resolutions for the microbending displacement sensor, the fiber reflectometer, and the macrobending temperature probe are 26 μm, 0.0006 RIU, and 3.9?C, respectively. In addition to a didactic kit for photonics classes, the proposed device can also be used as a portable sensor for multiple purposes since the transducer modulus can be exchanged to assess different physical and chemical variables.

[IEEE 2018 IEEE International Conference on Imaging Systems and Techniques (IST) - Krakow, Poland (2018.10.16-2018.10.18)] 2018 IEEE International Conference on Imaging Systems and Techniques (IST) - Performance and power consumption evaluation in smartphone based image processing for medical applications
摘要： More and more image processing applications are intended to run on mobile devices. This trend is visible also in medical industry, which have very strict reliability and safety requirements. Increased power consumption and inefficient image processing can affect both of these factors significantly. More over, it affects the user experience as well. In this paper authors investigates the performance and power consumption of several different numeric algorithms implemented on iPhone device. The comparison is made between CPU and GPU based solutions. Authors evaluated the test scenarios involving common used operations: matrix multiplication, thresholding and Canny’s edge detection. The results showed that GPU based solution can be up to 4 times faster as CPU based one, with similar power footprint in particular cases. All measurements have been gathered without hardware interference nor jailbreaking of the device. Finally authors discuss possible application considerations and scenarios in medical related image processing smartphone apps.
