And Control

In the supervisory control of a complex, dynamic system, one potential form of aiding for the human operator is a computer-based operator's associate. The design philosophy of the operator's associate is that of “amplifying” rather than automating human skills. In particular, the associate possesses understanding and control properties. Understanding allows it to infer operator intentions and thus form the basis for context-dependent advice and reminders; control properties allow the human operator to dynamically delegate individual tasks or subfunctions to the associate. This paper focuses on the design, implementation, and validation of the intent inferencing function. Two validation studies are described which empirically demonstrate the viability of the proposed approach to intent inferencing.

Representation Of Knowledge

A concept map (also known as a knowledge map) is a visual representation of knowledge of a domain. A concept map consists of nodes representing concepts, objects, events, or actions connected by directional links defining the semantic relationships between and among nodes. Graphically, a node is represented by a geometric object, such as a rectangle or oval, containing a textual name; relationship links between nodes appear as textually labeled lines with an arrowhead at one or both ends indicating the directionality of the represented relation. Together, nodes and links define propositions or assertions about a topic, domain, or thing. For example, an arrow labeled has beginning at a node labeled bird and ending at a wings node represents the proposition “A bird has wings” and might be a portion of a concept map concerning birds, as portrayed in Figure 1.

Computer Based

The first experiment found that varying the rate of road hazards in a personal-computer-based driving simulator had no effect on subjects' situation awareness, as measured in the simulator. Thus, setting a high rate of hazards does not distort subjects' situation awareness. In the second experiment, the situation awareness test was found to predict driving performance in a realistic simulator. Individual differences in situation awareness were correlated with working memory and psychomotor abilities.

Positive Results

The purpose of this experiment was to assess the efficacy of using real-time generated computer feedback of a selected biomechanical variable, force, for modifying the pattern-of-force application of inexperienced cyclists while they cycled at a steady rate (60 rpm) and power output (approximately 112 watts). Positive results would imply that the technique of using biomechanical variables as augmented feedback could be applied in a learning study in such a way to train for the enhancement of performance of cyclists. This approach differs from the traditional one of using novices performing novel tasks. Even though the cyclists were inexperienced, they nonetheless knew how to cycle and thus modifications of the pattern of force application were made to an already existing complex skill.

Mental Health Rehabilitation

The Low Energy Neuro feedback System (LENS) is one of the growing approaches used to bring Quality of life (QOL) to the patients suffering from mental health issues and Nervous system disorders by elevating the symptoms. It is a computer- based software program that is connected to EEG box which measure brain waves. This approach is different from Neuro feedback technique as it uses very low electromagnetic strength. It brings in noticeable improvement after few second of treatment session which does not require conscious awareness or voluntary participation from the client. It was first developed in the early 1900s by Dr Len Ochs to treat uncontrolled epilepsy, followed by many researches that signify its beneficence for treating many neurological and mental health disorders. This technique does not cure the disorder though it does elevate symptoms that improve the QOL. Although LENS is being exercise around the world, it is still unidentified by many professionals in Pakistan. Use of LENS adjacent to other therapies will bring revolution in Pakistan mental health rehabilitation. More research on LENS is suggested.

Disabled Readers

Synthesized speech was used in our Computer-Based Reading and Speech-Feedback system for training disabled readers. In this system, children touch unfamiliar words in stories presented on the computer display and receive speech feedback to help develop their word decoding skills. Results from a study of disabled readers' responses to the system are reported. The disabled readers could identify words spoken by the synthesizer nearly as well as the same words presented in natural speech. After reading stories and targeting unknown words with a mouse or light pen, the disabled readers were later able to read a high percentage of the targeted words for which they had received speech feedback. Extended use of the system may substantially improve the prognosis for disabled readers. The advantages of synthesized speech over other types of computer speech are discussed for this application.
