EFFECTS OF TARGET SIZE ON FINGER CONTACT AREA IN TOUCHING THE INTERFACE OF APPLIANCESKeyuan Zhou (6843002) 16 December 2020 (has links)

<p>This study focused on a physical property of human finger touch: finger contact area (FCA). The
value of FCA lies not only in optimizing the interface layout design but also in streamlining the
process of sensitivity tuning for capacitive devices. However, from previous research, whether the
target size and display position have effects on the FCA is unknown, and the data of FCA in the
contexts of touching various appliances had never been explored. A within-subjects experiment
was conducted to study the FCA in the context of four target sizes and two display positions. Forty-two participants were recruited, and both their demographic data as well as touch data were
collected and analyzed. As a result, both the target size and the display position have significant
effects on the FCA size, and users would implement different finger approach angles (FAA) in
varying contexts accordingly. In general, larger target size and vertical touch surface would lead
to a larger FCA size, but other factors such as finger joint circumference, stature, touch force did
not show significant effects in the experiment. Overall, this study contributes to a clearer
understanding of FCA data as well as how users behave in the touch interaction on the capacitive
touch interface of appliances. Moreover, it pointed out what factors were related or unrelated to
the FCA. This knowledge would directly help designers and engineers to develop optimized
capacitive buttons with appropriate sizes as well as sensitivity on touch interfaces of appliances
and could improve the usability of the capacitive touch interface in the future.

Linear and Circular Human ZNF292 RNAs Decrease after Anti-Cancer Treatment of HCT116 Colorectal Cancer CellsCarnevale, Patrick C., Geren, Kellee B., Lefevers, Kacey M., Klein, Jeffery D., Morris, Samantha C., Cartwright, Brian M., Palau, Victoria E., Hurley, David L. 07 April 2022 (has links)
ZNF292 is a gene that encodes for a large multifunctional zinc finger protein. ZNF292 has a role in Growth Hormone transcription, developmental disorders on the autism spectrum, and in the initiation of tumorigenesis. Cancer cells have revealed ZNF292 as a gene with unique features: it is present in both linear and circular RNA (circRNA) forms. Circular ZNF292 RNAs vary in size depending on the number of exons that are back-spliced together forming a nested set of babushkas or “Russian dolls” – larger forms add an exon to a smaller circle. To determine whether anti-cancer treatments change the expression of circRNA forms as well as the linear form of ZNF292, we performed quantitative Reverse Transcriptase Polymerase Chain Reaction (qRT-PCR) analysis. Primers used were designed to amplify only the specified form of ZNF292, either the linear form or one of four targeted circular forms. Control and flavone (3,5 dihydroxy-7-methoxyflavone)-treated cell lines were grown, harvested, and total RNA extracted. Then, samples were analyzed by qRT-PCR with specific ZNF292 primer sets for each product using a standard curve for comparisons. All results were normalized to actin levels in each sample prior to statistical analysis. When compared to untreated controls, two linear ZNF292 RNAs were each reduced to 52% of control levels (p

An open-source model and solution method to predict co-contraction in the index finger / An open-source musculoskeletal model and EMG-constrained static optimization solution method to predict co-contraction in the index fingerMacIntosh, Alexander January 2014 (has links)
Determining tendon tension in the finger is essential to understanding forces that may be detrimental to hand function. Direct measurement is not feasible, making biomechanical modelling the best way to estimate these forces. In this study, the intrinsic muscles and extensor mechanism were added to an existing model of the index finger, and as such, it has been named the Intrinsic model. The Intrinsic model of the index finger has 4 degrees of freedom and 7 muscles (with 14 components). Muscle properties and paths for all extrinsic and intrinsic muscles were derived from the literature. Two models were evaluated, the Intrinsic model and the model it was adapted from (identified in this thesis as the Extrinsic-only model). To complement the model, multiple static optimization solution methods were also developed that allowed for EMG-constrained solutions and applied objective functions to promote co-contraction. To test the models and solution methods, 10 participants performed 9 static pressing tasks at 3 force levels, and 5 free motion dynamic tasks at 2 speeds. Kinematics, contact forces, and EMG (from the extrinsic muscles and first dorsal interosseous) were collected. For all solution methods, muscle activity predicted using the Intrinsic model was compared to activity from the model currently available through open-source software (OpenSim). Just by using the Intrinsic model, co-contraction increased by 16% during static palmar pressing tasks. The EMG-constrained solution methods gave a smaller difference between predicted and experimental activity compared to the optimization-only approach (p < 0.03). The model and solution methods developed in this thesis improve co-contraction and tendon tension estimates in the finger. As such, this work contributes to our understanding of the control of the hand and the forces that may be detrimental to hand function. / Thesis / Master of Science (MSc)

EFFECT OF WRIST POSTURE AND RATE OF FORCE DEVELOPMENT ON FINGER CONTROL AND INDEPENDENCEMay, Stephen 18 November 2014 (has links)
The anatomical structure of the extrinsic finger muscles suggests that posture may play a role in the production of enslaved forces in the fingers. This phenomenon also appears dependent on contraction conditions. The purpose of this thesis was to determine the effect of: (i) wrist posture on the enslaving effect (EE) during ramp and isotonic exertions, and (ii) the rate of force development on EE and accuracy during ramp exertions. Twelve male participants performed 3 submaximal finger flexion and extension trials with the index and ring fingers at 30° wrist flexion, neutral, and 30° wrist extension. Trials consisted of a 5 second isotonic contraction at 25% MVC (maximum voluntary contraction), and two ramp contractions. Ramp contractions were performed at 25% MVC/s and 10% MVC/s up to 50% MVC, a 0.5 second hold, and decreased to zero at the same rate. Surface electromyography was recorded from the compartments of extensor digitorum and flexor digitorum superficialis and analyzed at 25% of maximum. Wrist posture had a significant effect on EE during extension exertions (F4, 44 > 2.6, p < 0.05); specifically, higher EE, error, and muscle activity were found at shorter muscle lengths. Contraction condition significantly affected EE for both index (p = 0.001) and ring finger exertions (p = 0.001). In the fingers adjacent to the task finger, descending phase EE was higher than the ascending phase, which appeared independent of muscle activity. This thesis found that, in extension exertions, neural factors affecting EE were dependent on muscle length, while mechanical factors appeared dependent on the type of exertion. These findings further our knowledge of the complex relationship between neural and mechanical control of the hand and fingers. / Thesis / Master of Science (MSc)
