2. Abstract

The focus of the document concerns the study and technique into the situation of people carefully needs having the ability to live independently of their own homes with lowest intervention. Elderly people particularly generally have an increased risk of dropping and sustaining serious damage than youthful people. Other people with certain medical ailments also have a higher risk of dropping scheduled to seizures, balance problems etc.

Current fall recognition alert systems are expensive and obtrusive. They might need landline phone cable connections and a call centre network with access to personal information to get hold of the appropriate carer. Receptors are rarely waterproof and can be easily harmed. What sort of sensors are continued your body can irritate and be annoying to the individual. One of the primary, costliest failures of current systems occur when a call button has been handled by accident, leading to accidental notifications being delivered to the call centre.

The main target of the research and proposed model is to offer an investigation into the opportunity of using new technology to give a far better system. Which Such something will work only for fall recognition and send notifications to appropriate employees with the option for camera usage of enabling them to see situation on way to notify.

Specifically the project seeks to discover if new wedding ring action detection technology can be used to provide a more cost effective way of discovering falls within the house. Provisioning of the sensor which is both waterproof and unobtrusive to the wearer, which can be used to send an alert via txt or email right to carers, thereby taking away the necessity for a pricey, dedicated landline alert system and call centre network.

7. Methodology

The research necessary to enable conclusion of the project will the follow the stream diagram used within Goals.

Secondary research will be carried out into what defines a fall. This will demand papers, articles, literature and websites to be read on the definition of what takes its fall. The info gained out of this research will be compared and contrasted in to dining tables to analyse what actions and positions best constitute a street to redemption and will cover the most likely scenarios for the system model.

During this research any currently available algorithms, diagrams and coding will be collated, analysed and used to determine the fall definition chosen for the task.

Another aspect required for the machine model is the final position of the street to redemption and the time of inactivity that would indicate a fall. The data will be collated and analysed using graphs and diagrams to choose the most likely solution that encompasses the most data to set-up an all-encompassing semester detection system. Time inactivity data will be accumulated from research data to compare time retrieved to choose the median body for inactivity and use this in the introduction of the system.

Then all the collated data will be likened analysed and a summary drawn, displaying the best options for the job, and the introduction of the equations required for coding of these devices sensors.

Once a show up definition has been decided on the terms used to program the device sensors needs to be researched and discovered. The sensor device has available software developer's kits (SDK) for android, iOS and UNIX amongst others. The usage of these kits will require a steep learning curve and require reading and taking sensible courses on learning the languages required. Learning the vocabulary, will be achieved through catalogs, online programs and available API's and code.

The Project Supervisor will help in the job ensuring the correct language is employed and coding is fit for purpose.

Although the ring comes with its software, other methods of programming appropriate to the current expertise will be explored, by contacting builders through the developer's community and other programmers to aid with encoding the detectors.

At this stage any compatibility problems with the sensor and devices will be noted and used during the trials of the completed model to aid improvements.

During the process of learning the coding vocabulary, the programming of the band employing this knowledge will be initiated. Sample rules will be modified and tested by programming the device to test operation.

Current show up technology research will include investigating current papers, applications and systems. Available current applications will be likened against the proposed project model to find out possible areas for improvement.

Initial alert sending coding will be designed within the jewelry SDK, producing results of positive fall season detection and sending these to a receiving device. Knowledge and encoding developed during research will be used to complete alert coding.

Testing will be completed using simulated notifications on various platforms, at different distances from sensor to platform stop. Results will be collated and displayed in graphs demonstrating comparisons and examination. The alert sending system which sends messages to cell phones and email messages will be designed using the SDK or terminology used to program other functions.

The completed model is to be tested using real comes which creates an moral issue. To address this matter local fighting techinques instructors will be approached to require their advice about testing. The trainers will be asked to supply the test equipment to classes in order to record falls that happen during normal category activities. To fulfil any ethical considerations these tests will be recorded and the correct paperwork for consent obtained. These lab tests will ensure street to redemption detection, alerts sending and getting and the effective range of the machine. The results will then be collated and reproduced in graphs, desks and illustrations to show success and inability rates, distance achieved and sending and getting times.

Future innovations are looked into through searching for added operation of the sensor devices used within the model and possible affordable enhancements which, when put into the system model increase the task and add features resulting in a reliable good care model.

The final step will be compiling the survey for submission. This may done by pooling all research, dining tables, graphs and coding into the documentation required for the MSc job.
