Augmentative and Alternative Communication (AAC) systems are designed to enable people to communicate with those around them when they are unable to do so themselves. Such people include those su ering from congenital diseases, such as cerebral palsy; progressive diseases, such as motor-neuron disease and multiple sclerosis; or those who have been the victim of a trauma, such as a head injury. ...

We detail the design, development and evaluation of Augmentative and Alternative Communication (AAC) software which encourages rapid conversational interaction. The system uses Natural Language Generation (NLG) technology to automatically generate conversational utterances from a domain knowledge base modelled from content suggested by a small AAC user group. Findings from this work are present...

We are building a tool that helps children with Complex Communication Needs 1 (CCN) to create stories about their day at school. The tool uses Natural Language Generation (NLG) technology to create a draft story based on sensor data of the child’s activities, which the child can edit. This work is still in its early stages, but we believe it has great potential to support interactive personal n...

Many people with severe speech and motor impairments make use of augmentative and alternative communication (AAC) systems. These systems can employ a variety of techniques to organize stored words, phrases, and sentences, and to make them available to the user. It is argued in this paper that an AAC system should make better use of the regularities in an individual’s conversational experiences ...

Individuals using an Augmentative and Alternative Communication (AAC) device communicate at less than 10% of the speed of “traditional” speech, creating a large communication gap. In this user study, we compare the communication rate of pseudo-impaired individuals using two different word prediction algorithms and a system without word prediction. Our results show that word prediction can incre...

a sustained-release tablet formulation should ideally have a proper release profile insensitive to moderate changes in tablet hardness that is usually encountered in manufacturing. in this study, matrix aspirin (acetylsalicylic acid) tablets with ethylcellulose (ec), eudragit rs100 (rs), and eudragit s100 (s) were prepared by direct compression. the release behaviors were then studied in two co...

in the present investigation an attempt has been made to increase therapeutic efficacy, to reduce frequency of administration and to improve patient compliance by developing a sustained release matrix tablets of isosorbide-5-mononitrate. sustained release matrix tablets of isosorbide-5-mononitrate were developed by using different drug: polymer ratios, such in f1 (1:0.75), f2 (1:1), f3 (1:1.5),...

hard gelatin capsule filled with acetaminophen, osmotic agent (sorbitol), a release promoter (sodium dodecyl sulfate), coated with a semipermeable cellulose acetate membrane containing a hydrophobic plasticizer (castor oil) and sealed with white bees wax plug was designed. when placed in the sink water penetrates the membrane, dissolves the osmotic agent and increases the osmotic pressure insid...
