An Overview of the Capabilities and Limitations of Smartphone Sensors
International Journal of Handheld Computing Research, 2013Few technical details are available about the various sensors embedded in modern smartphones, and what details are available can be hard to assemble and interpret by the broader technical community that uses these devices. Since the physical and electromagnetic aspects of the sensors' operation can significantly affect the analysis and use of their ...

Meticulous Alignment for On-Display Fingerprint Sensor on Smartphone
2021 IEEE International Conference on Consumer Electronics-Taiwan (ICCE-TW), 2021This paper presents a fingerprint alignment algorithm based on the latest on-display optical fingerprint image sensors used for the brand-new smartphone. In order to avoid finding very similar but wrong alignment results, fingerprint ridges are used for matching instead of minutia points.

Human-Activity Recognition with Smartphone Sensors
2020The aim of the Human-Activity Recognition (HAR) is to identify the actions carried out by an individual given a data set of parameters recorded by sensors. Successful HAR research has focused on the recognition of relatively simple activities, as sitting or walking and its applications are mainly useful in the fields of healthcare, tele-immersion or ...

Verification and Validation of Smartphone Sensor Networks
2012This paper introduces a subset of mobile wireless sensor networks, called smartphone sensor networks, where large numbers of smartphone devices cooperate to perform sensing tasks. While these emerging networks show high potential, little work has been done on design-time verification and validation to ensure that a designed system will meet the ...

The Android smartphone as an inexpensive sentry ground sensor
SPIE Proceedings, 2012A key challenge of sentry and monitoring duties is detection of approaching people in areas of little human traffic. We are exploring smartphones as easily available, easily portable, and less expensive alternatives to traditional military sensors for this task, where the sensors are already integrated into the package.

Analyzing collision processes with the smartphone acceleration sensor
The Physics Teacher, 2014It has been illustrated several times how the built-in acceleration sensors of smartphones can be used gainfully for quantitative experiments in school and university settings (see the overview in Ref. 1). The physical issues in that case are manifold and apply, for example, to free fall,2 radial acceleration,3 several pendula,4,5 or the exploitation ...

Indoor localization using smartphone inertial sensors
2014 11th Workshop on Positioning, Navigation and Communication (WPNC), 2014Celebrated fingerprinting techniques localize users by statistically learning the signal to location relations. However, collecting a lot of labelled data to train an accurate localization model is expensive and labour-intensive. In this paper, an economic and easy-to-deploy indoor localization model suitable for ubiquitous smartphone platforms is ...
