Summary
Smart Predict, a two-tablet augmentative and alternative communication (AAC) system, enhances conversational efficiency for users. This technology improves message speed and user satisfaction by integrating partner vocabulary supplementation.
Area of Science:
- Augmentative and Alternative Communication (AAC)
- Human-Computer Interaction
- Assistive Technology
Background:
- Conversational efficiency is a key challenge for individuals using AAC devices.
- Existing AAC systems often lack real-time vocabulary support from communication partners.
- The Smart Predict system was developed to address these limitations.
Purpose of the Study:
- To evaluate the impact of the Smart Predict system on message efficiency for AAC users.
- To assess user satisfaction and perceived workload with the Smart Predict system.
- To explore the feasibility of integrating partner-provided vocabulary in AAC.
Main Methods:
- A novel two-tablet application, Smart Predict, was developed for Android devices.
- Single-case research designs with adapted alternating treatments were employed.
- Message efficiency (characters per minute, switch selections per character) and user experience were measured in three adults with complex communication needs.
Main Results:
- The dual-tablet Smart Predict system significantly increased message efficiency compared to the AAC User app alone.
- Users reported higher satisfaction and decreased perceived effort when using Smart Predict.
- Faster message generation was observed with the integrated vocabulary supplementation.
Conclusions:
- The Smart Predict system demonstrates a viable approach to enhancing conversational efficiency in AAC.
- Integrating real-time vocabulary supplementation from communication partners is beneficial for AAC users.
- Smart Predict represents a promising feature for future smart AAC technologies.

01:27Air-entraining Agents
76
Air-entraining agents improve the durability and workability of concrete in climates with frequent freezing and thawing. These agents prevent cracks by introducing small air bubbles into the mix, creating spaces accommodating water expansion when temperatures drop. The air-entraining agents lower the surface tension of water, forming stable, small air bubbles. This method is more effective than having accidental large voids, as the intentional, smaller, and evenly distributed air voids improve...

01:24Components of Language
261
Language, whether spoken, signed, or written, consists of specific components: lexicon and grammar. The lexicon is the vocabulary of a language, comprising its words. Grammar is the set of rules used to convey meaning through the lexicon. For example, English grammar adds “-ed” to most verbs to indicate past tense. Words are formed by combining phonemes, which are the basic sound units of a language. Different languages have different sets of phonemes (e.g., “ah” vs.

01:22Language Development
329
Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

01:14Design Example: Resistive Touchscreen
299
A device engineer plays a crucial role in designing user interfaces for mobile devices. One such interface is the resistive touchscreen, which fundamentally consists of two metallic layers: a flexible upper layer and a rigid lower layer, separated by a narrow gap. The high resistance between these two layers is a key characteristic of this design.
When a user touches the screen, the two layers make contact at a specific point known as the touchpoint. This contact reduces the resistance between...

1.3K
Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...
