Gestures During Infancy and Toddlerhood

Gestures are nonverbal movements of the hands, arms, or face that allow infants and toddlers to communicate emotions, needs, and intentions before speech develops. Gesture use generally appears before spoken language and decreases as vocabulary expands. For example, an 11-month-old may raise their arms to request being picked up, whereas an 18-month-old may say “up.”Types of GesturesChildren mainly use deictic and representational gestures. Deictic gestures emerge around six months and include...

The paper presents a comprehensive protocol for simultaneously recording hand-electromyography (EMG) and visual finger tracking during natural finger gesturing. The visual data is designed to serve as the ground truth for the development of accurate EMG-based computational models for finger gesture recognition.

Here, we present a protocol that manipulates interlocutor visibility to examine its impact on gesture production in interpersonal communication. This protocol is flexible to tasks implemented, gestures examined, and communication modality. It is ideal for populations with communication challenges, such as second language learners and individuals with autism spectrum disorder.

Control System Problem

In an open-loop system, such as a basic thermostat, the poles of the transfer function influence the system's response but do not determine its stability. However, when feedback is introduced to form a closed-loop system, such as an advanced thermostat that adjusts heating based on room temperature, stability is governed by the new poles of the closed-loop transfer function. When forming a closed-loop system, issues can arise if the poles cross into the unstable region, leading to potential...

2024
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy. Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast, controlled...

These sensing options provide different ways to capture movement data. Cameras observe body or hand motion, depth sensors add information about spatial positioning, inertial measurement units measure movement through a device, and wearable sensors capture motion from the user’s body. Engineers select among them when designing interfaces for robotics, vehicles, automation, or immersive systems.
The system first receives movement data from its sensing hardware. Computer-vision and pattern-recognition algorithms then identify meaningful gesture patterns within that data. After recognition, the system translates the interpreted gesture into a control signal that an attached device can use. This processing chain connects physical movement with an operational command without requiring direct contact.
Its main advantage is contact-free interaction, which helps when physical controls are impractical or could become contaminated. Hands-free operation can also support accessibility and safer interaction in appropriate environments. Unlike conventional interfaces that require contact with a control surface, gestures allow users to issue commands through movement captured by sensing hardware.
An implementation begins by selecting sensing hardware suited to the intended interaction, such as cameras, depth sensors, inertial measurement units, or wearables. The system then captures movement data, applies computer-vision or pattern-recognition methods to identify gestures, and maps recognized movements to control signals. Engineers integrate this pipeline with the target device or application.
Engineering applications include robotics, industrial automation, vehicle interfaces, assistive technologies, and virtual or augmented reality systems. In robotics and automation, gestures can provide an alternative interaction channel; in vehicles, they can support interface control; and in immersive or assistive systems, movement-based commands can connect users with digital or physical functions.
Gesture control can reduce dependence on physical input devices, allowing hands-free interaction where buttons, keyboards, or touchscreens are difficult to use. That capability may support assistive technologies and improve accessibility for some users. It can also help in environments where contact is impractical or contamination of shared physical controls is a concern.
