“Good design is about making a product or design that serves a function better than anything else that has gone before it. It’s about looking at everyday things with new eyes, and working out how they can be made better.” -- James Dyson

PROJECT OUTLINE For the scheduled Fall 2013 interdisciplinary course, ID / OT / Pharmacy / Computing Science will be looking at the research and development of specific elements that could be installed into the Smart Condo. Artifacts such as a kitchen cabinet with pull down shelving, clothes storage system in bedroom closets and chest of drawers, bathroom wash basin cabinets with medicine storage, strategic adjustable railing system throughout the condo (washroom, kitchen, bedroom) are but a few of the design issues. This project is aimed at finding creative and unique solutions to the needs that you discover through your research. To help you with this, you will be given specific readings and input from your instructors, visiting lecturers and fellow classmates resulting in a body of knowledge that will assist you in developing your design solutions. The final designs will be the result of collaboration between all the members of your team and will reflect the solid research conducted by the teams and a working knowledge of Universal Design principles. Through collaboration with the dental hygiene faculty to understand oral health needs, and analyze the activity for teeth brushing among older adults with early dementia, the goal of this project is to design or propose a solution that facilitates independence in teeth brushing among this population. For this project, the Memori™ dental hygiene system is intended to act as a guide to assist individuals suffering from early dementia. Through the utilization of various cues, this design will provide an interactive feedback system with the ability to direct individuals through the basic stages of toothbrushing.

MILD DEMENTIA is characterized by visible cognitive and physical changes that include difficulty in retaining and learning new information, judgment errors, gradual disorientation in time and space, and changes in personality

INCREASED RISK these cognitive changes and difficulties with motor skills involved in oral and self-care activities increase the risk of developing medical complications and oral diseases (Ghezzi & Ship, 2000)

ALZHEIMER’S DISEASE is the most common form of dementia and is characterized by irreversible progressive neurological degeneration causing impairment in the domains of social, functional and occupational capacity (American Psychiatric Association, 2000) In 2008, approximately 500 000 people, or 1.5% of the Canadian population was living with AD or a related dementia. By 2038,

Dental hygiene tends to become a minor priority for people suffering from dementia

DECREASED ORAL HYGIENE in people with dementia can be attributed to side effects from pharmaceutical treatments. Side effects from these drugs include decreased salivation, which negatively affects oral health

COGNITIVE CHANGES and difficulties with motor skills involved in oral and self-care activities increase the risk of developing medical complications and oral diseases (Ghezzi & Ship, 2000) Poor gingival health has been found to increase the severity of dementia

DUE TO THE COMPLEXITY OF THE TOOTH BRUSHING PROCESS, SOME CLIENT SKILLS WILL NEED TO BE CONSIDERED

COGNITIVE SKILLS coping skill to manage potential frustration with system time management skills and ability to follow routine concentration/attention span to complete activity ability to follow steps and instructions sense of body position in space ability to identify objects

MOTOR SKILLS intrinsic hand muscles to grasp objects used in activity endurance to complete entire activity without breaks radial and ulnar deviation of the wrist flexion and extension of the elbow all movements of the shoulder bilateral hand movement

DESIGN CONCEPT & IDEATION This project focuses on the concept of creating a dental hygiene system that serves as a reminder and guiding system for individuals suffering from mild dementia. The Memori™ system is designed to present an aesthetically familiar and sterile product that incorporates an interactive interface. The design of this system will consist of an electronic toothbrush, docking system, and interface system that will communicate with one another visually and systematically. The system will utilize contrasting materials, textures and colours in order to present a non-institutionalized and home friendly aesthetic. In regards to functionality, the use of various visual, audio, and haptic cues will assist in creating a structured, non-threatening interactive dental hygiene system.

TOOTHBRUSH DESIGN The toothbrush component of this system places emphasis on ergonomics in regards to gripping and handling. By incorporating various organic curves, the brush handle is intended to provide users of various ability levels (ie. arthritis) ease and comfort while brushing their teeth. The toothbrush utilizes small strips of sensors at the end of the handle to allow for communication with the interface system in order to provide auditory and visual cues. Due to the time restraint of the project, this system does not research into the specifics of brush head designs and will utilize the American Dental association recommended Oral B toothbrush head.

MOTION TRACKING MARKER SYSTEM The bottom of the toothbrush handle incorporates a marker system in which motion can be detected through the RGB camera that is embedded in the interface system. The marker system will allow for the tracking of the angle and position of the toothbrush in order to provide user feedback during the step by step process

SYSTEM INTERFACE DESIGN The interface component of the system utilizes a series of visual and auditory cues to guide users through a step by step process. A set of comprehensible icons have been created in order to provide an understandable visual aspect which would be accompanied by simple directions in readable and verbal forms. A key feature of the system is its intention to interactively determine where individuals should brush and the length of time to brush through the use of an embedded RGB camera.

UTILIZATION OF ICONOGRAPHY The use of icons will provide users with an easy to understand visual system to guide them through a step by step tooth brushing process. The approximate thirty-two step activity has been broken down into eight groups which correspond to specific icons. These icons are not intended to highlight each and every individual step, but rather provide a recognizable visual cue in which a number of steps can be grouped under.

STEPS 12 THROUGH 14: BRUSHING THE TEETH “The mouth is the gateway to a person’s overall health, and an unhealthy mouth can be associated with obesity, diabetes and even heart disease” (American Dental Association). As suggested by the American Dental Association, brushing for two minutes twice a day can help to prevent tooth decay. In order to ensure that individuals brush all of their teeth, the system divides the mouth into four quadrants (top left, top right, bottom left, bottom right). The interface system as well the toothbrush itself will provide visual, auditory and haptic cues in thirty second time spans to notify individuals when to start and stop brushing a particular quadrant.
