Intelligent Pillbox : Automatic and Programmable Assistive Technology Device

Intelligent Pillbox : Automatic and Programmable Assistive Technology Device

Improving lifestyle not only in elderly sick people also in general sick people is a main goal of this development; our device involves reliability and usability with a friendly technology. In the case of elderly people as in Marceline. It is well known with the years, the gradual degradation of faculties can affect the ability to cope with machine technology that is nowadays common in public spaces, like telephone cards and ticket machines (which requires physical and mental agility) or automatic tellers (where codes are needed to be memorized and alternatives must be selected rapidly). It is important to understand that these devices could become more an obstacle than an aid. This conclusion obtained through a study using two generations of men and women (aged 55-74 and 75+ years, respectively), giving us a way to focus our priorities in development of a pillbox, considering parameters to interact correctly with elderly users mainly. Achieving an appropriate reminder system combined with a new type of programming dosages inside a device may be a possible solution to currently interface that nowadays are everywhere to interact in a better way with a keeper or doctor who are tied most of the time to keep track from their patients, who can use easily technology interfaces. Give them partially release from that responsibility and focus only in load dosage in device. While the interaction between patient and object won't be deep, is necessary to give a solution which doesn't complicate prospective interaction patient pillbox, even though interact between them through technology is an important contribution which this work looks for.

The Need for Assistive Technology in Educational Technology

The Need for Assistive Technology in Educational Technology

As part of the federal IDEA amendments, there are statements that now require assistive technology devices and services to be considered on an individualized basis and become a part of the individual education plan (IEP) if the child needs them to benefit from his educational program. Based on NCATE accreditation requirements, it would be reasonable for a school administrator to expect that an educational or instructional technology graduate from an NCATE accredited program would be able to effectively participate on a student’s IEP team. These expectations would include that such a

Content analysis to locate assistive technology in Queensland’s motor injury insurance rehabilitation legislation and guidelines

Content analysis to locate assistive technology in Queensland’s motor injury insurance rehabilitation legislation and guidelines

The definition of rehabilitation in the legislation is consistent with contemporary international interpretations that focus on optimizing functioning in interaction with the environment. However, the supporting guidelines and standards are explicitly framed by a medical model focused on recovery from injuries, where decisions are guided by clinical need and affordability. This may limit the range of interventions considered and exclude strategies likely to promote quality of life, including assistive technology devices and services and universally designed products. Aids and equipment, home modifications and vehicle modifications are being provided as part of rehabilitation, but there is not a framework or monitoring capacity for the assessment of needs, coordination and implementation of interventions, follow-up and maintenance, or measurement of outcomes.

Enhancing electronic assistive technology prescription

Enhancing electronic assistive technology prescription

With the procurement of the position at CES, a personal interest began to develop not only with regard to the functional restriction of these software applications but, in addition, the validation processes for individuals who often had no other way of speaking but through the system itself. This in turn can limit the individual in what they say for two reasons. Firstly that often the individual they are communicating with is the same individual who created the system. This puts the user in the uncomfortable position of having to tell the individual who maintains the system, what is wrong with the system that they have created. Secondly, if an item does not exist with the statement which describes the user’s feelings with regard to the system, then it can take a great deal of effort and time by the disabled individual to spell out word for word their concerns. Due to the physical demands of spelling word for word, eventually physical exhaustion ensues and this, together with an element of frustration at not being able to say what they wish to say, the user will often not express their feelings and will stop trying completely - leaving the creator no wiser than when they started. Thus, from the invention of EAT, individuals such as Assistive Technology Professionals1 (ATP’s) and funding organisations have sought to be able to evaluate EAT systems usage (Cherry et al.{1996), Churchill (1998), Keats et al.( 2000), O’Neill et al. (2000)). Their rationale for validating these devices is three fold:

Assistive Technology: Use and Service Delivery

Assistive Technology: Use and Service Delivery

A model for assessing the component interactions of the service delivery system has been developed to provide a framework for understanding how AT and the services often needed for acquiring AT can change performance of people with disabilities. This model, the human activity assistive technology model (HAAT), postulates four components: human, activity, assistive technology, and context. All components must be considered when selecting an AT device. For simple, inexpensive AT, consumers require little if any help in acquiring devices. However, when the AT device is complex, costly, or paid for by a third party, the process of obtaining the device can require the help of individuals trained in providing AT services. The services needed may include evaluations for the types of AT that are needed to enhance physical, sensory, and cognitive functions; improve performance in activities; and increase participation in major life activities. The evaluation may involve an interdisciplinary team of people who have training in engineering, therapy, medicine, and device use. The introduction of AT into the life of a person with a disability requires an analysis of the existing capacities

Design of an Assistive Walking Device with Special Rehabilitation Capabilities

Design of an Assistive Walking Device with Special Rehabilitation Capabilities

With this telecommunication device, the therapist does not need to be by the side of each patient. Thus a voice communication system has to be set up to allow the therapist and the patient to talk to each other in case of emergency or any urgent matters. This is especially good where the care center is huge and the patient may be far away from the therapist’s desk. A simple existing technology can be used in this application to establish a voice communication such as using a set of walkie-talkies.

The present study allows researchers and clinicians to better understand the PW users’ opinion about the impact of AT on their lives and, also, about the services provided, which may help to improve the quality of such services and the characteristics of the PW, according to preferences and needs. These improvements may, in turn, lead to a more positive impact of the PW on persons with disabilities’ lives, facilitating their interaction with the surrounding environment, promoting their social participation and, consequently, improving their QoL. Successful assistive technology product interventions are complex and include much more than the simple selection of the right product. Assistive technology product use is highly context sensitive in terms of the person with disabilities’ environment. As a field, we have much to study and develop around assistive technology product interventions from a global perspective [28].

Recent trends in assistive technology for mobility

Recent trends in assistive technology for mobility

Our discussions with our European peers suggest several areas limit our advancement rate. First, the components used to 'build' the assistive technology limits us. Any assist- ive technology is only as durable, light, and small as the available building blocks. For example, if exoskeletons are to become a viable mobility option for the non-ambulatory, they must be extremely lightweight, and therefore all structural components, actuators, and power sources must decrease in weight. A second core limitation is the relative immaturity of our control algorithms. As an ex- ample, using an exoskeleton to recreate the body's abil- ity to move smoothly over varied terrain at varied rates requires intimate access to the user's intended move- ments, along with sophisticated control algorithms to adjust to the complex, unstable, and varying dynamics of the user’s body and the walking environment. Finally, if the developed technologies are to gain user accept- ance and widespread adoption, control interfaces must be intuitive, seamless, and non-obtrusive. Component advancements will achieve seamless and non-obtrusive interfaces. Control algorithm advancements will achieve intuitive control. However, only persons with disabilities can provide design specifications for ‘ intuitive ’ , ‘ seamless ’ ,

Brainport Vision Technology

Brainport Vision Technology

With the current system (arrays containing 100 to 600+ electrodes), study participants have been able to recognize high-contrast objects, their location, movement, and some aspects of perspective and depth. Trained blind participants use information from the tongue display to augment understanding of the environment. Our ongoing research with the Brain Port vision device demonstrates the great potential of tactile vision augmentation and we believe that these findings warrant further exploration. As a result, we are currently working on improvements to the tongue display hardware, software, and usability, and on overall device miniaturization. The system includes the following: A miniature 2-axis accelerometer (Analog Devices ADXL202) was mounted on a low-mass plastic hard hat Anterior-posterior and medial-lateral angular displacement data (derived by double integration of acceleration data) were fed to a previously developed tongue display unit (TDU) that generates a patterned stimulus on a 100 or144-point electro tactile array (10x10 or 12 x 12 matrix of 1.8 mm diameter gold-plated electrodes on 2.3 mm centers) held against the superior, anterior surface of the tongue. Subjects readily perceived both position and motion of a small 'target' stimulus on the tongue display, and interpreted this information to make corrective postural adjustments, causing the target stimulus to become cantered. Thirty nine research subjects used the Brain Port balance device for a period from 3 to 5 days. The subjects included 19 males and 20 females ranging in age from 25 to 78 years, an average age of 55 years. Etiologies of the balance disorders included, but were not limited, to peripheral vestibular disorders, central

Assistive technology evolving as intelligent system

Assistive technology evolving as intelligent system

Abstract - Different evolving technologies surround humans today. Among the various technologies, Assistive Technology has still not established itself firmly because there is an absence of proper integration of this technology with human life. However, in the future, it will become one of the most important and vital phenomena in everyone’s life. Because humans want to make their life easier and longer and these are the reasons for the rapid growth in demand for Assistive Technology. Therefore, improvements in the technology and the way it is applied are essential and, for this reason, there is a requirement of a detailed study of the technology. This paper demonstrates the different milestones achieved in assistive technology by using different techniques to attempt to improve intelligence in assistive systems; and also, it describes the gaps that are still present even after such extensive works and, which are required to be either resolved or bridged. This study is done to understand where the assistive technology is today and in which direction it needs to get directed.

Assistive technology provision: towards an international framework for assuring availability and accessibility of affordable high-quality assistive technology

An additional problem is that the AT market is not an open market, in the sense that end users generally have very little choice. Decisions are made by intermediary bodies like insurance companies or municipalities, or by donor driven organisations and projects, but very rarely the user directly. This creates a market in which there are clear needs but users without direct purchasing power. Additionally, procurement of AT products is often outsourced to third parties. While bulk procurement of assistive products by governments, insurance companies or other agencies can reduce time, effort and costs, it increases the distance between end users’ needs and outcomes and purchasing

Towards an intraoral-based silent speech restoration system for post-laryngectomy voice replacement

Towards an intraoral-based silent speech restoration system for post-laryngectomy voice replacement

The operational block diagram of the intraoral version of the PMA system is present- ed in Fig. 3 . A command is sent wirelessly from the processing unit to the intraoral sensing module via Bluetooth to trigger data acquisition. All three tri-axial magnetic sensors then measure the three components of magnetic field and digitize it with 12- bit resolution. The microcontroller acquires these measurements (9 PMA channels sampled at 80 Hz) through managing a multiplexer using three control signals (S0, S1 and SCL). The multiplexer acts as a switching device to route the serial clock (SCL) to the desired magnetic sensor through the I 2 C interface. The acquired samples are then transmitted back to the processing unit wirelessly via the Bluetooth transceiver and custom designed Bluetooth dongle (in Fig. 3(b)) for further processing. Unlike the external version of the PMA prototype, the intraoral device is restricted to only operate wirelessly from inside the mouth. Hence, wired connectivity is impossible, as the sensing modules are to be sealed and packaged inside a dental retainer. In terms of software, a bespoke MATLAB-based graphical user interface (GUI) developed in [20] was adapted, where all speech processing and recognition algorithms were em- bedded.

A novel, neuroscience based control paradigm for wearable assistive devices : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Engineering at Massey University, Albany, New Zealand

The biological domain has evolved in such a way that it efficiently overcomes many problems we struggle to solve in the engineering domain; for example, bipedal lo- comotion, which requires a number of desirable attributes, e.g. compliance and adaptability. As such, the aim of this research has been to provide a bridge between the biological and engineering domains, capturing these attributes, and developing an enabling control technology. The application of this research has been around wearable assistive devices: devices that assist rehabilitation and recuperation of lost or impaired functions or enable an end user to perform difficult to complete tasks. As such, this thesis presents a novel, neuroscience-based control technology for wear- able assistive devices. Major contributions of this work include reproducing both biological movement’s compliant and adaptive properties in the engineering domain. The presented approach consists of using an assistive device, whose joints are antagonistically actuated using compliant pneumatic muscles, and central pattern generators. The assistive device’s actuators make the arm robust to collision and give it smooth, compliant motion. The pattern generators produce the rhythmic commands of the joints of the assistive device, and the feedback of the joints’ motion is used to modify each pattern generator’s behaviour. The pattern generator enables the resonant properties of the assistive device to be exploited to perform a number of simulated rhythmic tasks.
