In this paper, the author introduces a novel method for non-invasive, implicit human-computer interaction based on dynamically evaluated sitting postures. The research question addressed is whether or not the proposed system is able to allow for non-obtrusive screen content adaptation in a reading situation. To this end, the author has integrated force sensor array mats into a traditional offic...

Catherine Shin1,2, Alexander P. Willmott1, David R. Mullineaux1 & Paul Worsfold2 1University of Lincoln, Lincoln, UK, 2English Institute of Sport, UK In water sports, where accurate biomechanical measurement in situ is difficult, ergometers are frequently used to test athletes. Many kayak ergometer designs involve a bungee to assist in returning the athlete/paddle to the correct position for th...

We have set about the goal of developing a bungee jump system that will provide an ideal experience for a falling egg by maximizing the passenger’s free fall time, minimizing the force it experiences during deceleration, and not allowing the passenger to hit the ground. In order to develop an ideal bungee system, we must first determine the properties of our bungee cord. Under the assumption th...

We studied the effect of age on the act of rising from a standard armchair in a younger (means = 24 years) and an older (means = 75 years) group of healthy adult women. Rising from a standard armchair and an armchair specially designed for comfort in sitting of the elderly was studied in the older group to determine the influence of the special chair. We used electrogoniometry, EMG, and videota...

Triterpenes are natural products of plants that can defend against microorganisms and various stresses. Oxidosqualene cyclase (OSC), the key rate-limiting enzyme triterpene biosynthetic pathway, catalyzes 2,3-oxidosqualene into sterols triterpenes with different skeletons through chair–boat–chair (CBC) conformation or chair–chair–chair (CCC) conformation. They were expanded in mainly by tandem ...

OBJECTIVE To determine how modifications of key chair design aspects, such as seat height, posterior seat tilt, backrest recline, seat compressibility, and armrest placement, affect how older adults rise from a chair and the seating comfort they experience. DESIGN Cross-sectional comparison. SETTING Congregate housing facility and university laboratory. SUBJECTS Two groups of volunteers, ...
