To increase the quality of citizens' lives, we designed a personalized smart chair system to recognize sitting behaviors. The system can receive surface pressure data from the designed sensor and provide feedback for guiding the user towards proper sitting postures. We used a liquid state machine and a logistic regression classifier to construct a...
This letter presents a transducer network framework that supports the amalgamation of multiple transducers into single wireless nodes. This approach is aimed at decreasing energy consumption by reducing the number of wireless transceivers involved in such networks. To make wireless nodes easily reconfigurable, a plug and play mechanism is applied t...

The use of the digital twin has been quickly adopted in industry in recent years and continues to gain momentum. The recent redefinition of the digital twin from the digital replica of a physical asset to the replica of a living or nonliving entity has increased its potential. The digital twin not only disrupts industrial processes, but also expand...
Self-awareness is the foundation of emotional intelligence. Most people can recognize their own and others’ emotions. However, many people suffer from a common infirmity that prevents them from recognizing emotion within themselves and are therefore unable to experience a life that fulfills them emotionally. We propose a real-time mobile biofeedbac...
Muscle strength is mostly measured by wearable devices. However, wearing such devices is a tedious, unpleasant, and sometimes impossible task for stroke patients. In this paper, a mathematical model is proposed to estimate the strength of the upper limb muscles of a stroke patient by using Microsoft Kinect sensor. A prototype exergame is designed a...
This paper presents the Simple Internet of Things Enabler (SITE), a smart home solution that allows users to specify and centrally control IoT smart objects. Unlike most existing systems, SITE supports End-User Development. Hence, it defines a simple language for the specification of control rules for smart objects. It also provides a user interfac...
Systems and methods are provided for a dynamic user interface for interacting with computer applications by a user physically manipulating interactive floor tiles. The interactive floor tiles may be networked, and may use a communication bus 204 within the network for communicating the connection status of tiles in the network and/or any user input...

The impairment of the fingers is one of the main problems that prevents patients performing their daily activities. Researchers have used virtual environment combined with haptic feedback to improve the strength of the fingers. In this study, we design and implement a cost-effective, light, and easy to use haptic glove that helps patients in their...
Obesity rates in the world, especially in the developed countries are alarming. This has forced scientists to consider obesity as an epidemic due to its huge negative consequences on the societies' physical and mental health. Obese Children constitute a large portion of those affected by this epidemic and researchers are striving to find solutions...
We design and implement a low-cost rehabilitation glove to meet the needs of those patients who have paralysis in their affected hand. The novelty of this glove is that it is to be worn on the unaffected hand which acts as a natural robotic arm during the rehabilitation session. The glove is equipped with FSR sensors that measure the forces exerted...

Some diabetic patients experience difficulties in modulating the grip force magnitude when they manipulate objects using their hands. This difficulty is caused by the sensory loss at the fingertips that impairs the feedback loop between the brain and the aforementioned sensors. In this paper, we present a sensory substitution system called “F-Glove...
In this paper we present SmartInsole, a physical activity and gait measuring system integrated inside an insole. To achieve its goal, it uses force and acceleration sensors that track the wearer’s movements. The device is fitted with a radio transceiver in order to convey measured information to listening computers. Contrary to previous works which...
One common concern with video games today is the lack of physical activity they demand from the user. The design of games and tangible user interfaces (TUIs) that stimulate players and engage them into fun exercising activities is starting to attract the attention of many researchers and companies. This paper presents the software and hardware desi...
Obesity has recently become an epidemic that endangers the well-being of all the modern societies, especially the young generations. The lack of physical activity is considered as one major reason that contributes to such culprit. Exergames or Serious games have emerged as promising tools that can help in the fight against obesity because it promot...
It is a common practice to process analogue signals and give the results in digital form. This letter introduces a simple non-linear circuit that performs a hybrid multiplication based on the quarter-square principle. It employs a time shared square voltage-to-frequency converter as well as a simple digital counting circuit.
The paper describes the development of an electronic power factor meter to replace the conventional electrodynamic type. The design is based on a non-linear analogue-to-digital converter (NL-ADC). Each of the alternating voltage and current signals is applied to a zero-crossing detector and then exclusive OR-ed and filtered to obtain a DC signal pr...
The paper describes a non-linear analogue-to-digital converter (NL-ADC) whose output is proportional to the natural logarithm of the input voltage. It is based on Maclaurin's series of the natural logarithm function. The design is based on voltage-to-frequency conversion (VFC) and a decimal rate multiplier (DRM). The NL-ADC introduces four digital...
A method is introduced for finding non-linear functions digitally. The design is based on voltage-to-frequency conversion (VFC) and decimal rate multiplication (DRM). A DC signal is applied to the VFC and analogue comparator, producing a digital number proportional to the square of the input voltage. For the second half-period, this digital number...
