Slides 10-19

Slide 10 - The high frequencies of sound are lost when an aging individual endures presbycusis.

Slide 11 - Vision changes over time are complex and numerous.

Slide 12 - Changes to the eye result in the following changes in acuity and perception.

Slide 13 - Vision and Aging: The human eye is a "camera" device - meaning that it uses a lens to focus light on a surface called the retina.

Slide 14 - Vision and Aging: The human eye has varying degrees of sensitivity to color in light.

Slide 15 - Vision and Aging: Changes in the human eye that occur progressively.

Slide 16 - Vision: Primary Colors in Pigment.

Slide 17 - Vision: Primary Colors in Light.

Slide 18 - We see shapes in colors differently.

Slide 19 - Observe the differentiation between the "figures" and "grounds" below.

Slides 20-29

Slide 20 - Vision: The following guidelines should be followed in the application of text.

Slide 21 - Redundant Cueing.

Slide 22 - Closely related colors with regard to intensity and value- especially in the blue and green range- become difficult to differentiate from one another.

Slide 23 - Lens Opacity and Glare.

Slide 24 - Glare is one of the most significant problems within the domain of control by the architect, interior designer and product designer.

Slide 25 - The outdoor environment poses significant challenges for older adults especially on bright days when direct glare, as well as other forms of glare, is at its highest.

Slide 26 - Glare is exacerbated in this outdoor situation by the problems of low level accommodation and adaptation.

Slide 27 - The high amount of glare and the confusing array of shadows falling across the steps visually flattens the distances between steps, making the wood plank landing seem like a continuous surface and increasing the difficulty in finding the edges of the steps.

Slide 28 - Subtle changes in surface can present dangerous obstacles.

Slide 29 - Watch Your Step.

Slides 30-39

Slide 30 - The view through the windshield of a car, over a glare reflecting hood and into an ever changing landscape of light, vehicles and objects.

Slide 31 - In recent years, the automobile companies have been more conscientious in their design of interior and exterior surfaces relating to the transmission of unwanted illumination or glare.

Slide 32 - Automotive control and displays vary with the model year and frequently good design is lost as technology and styles change.

Slide 33 - Conditions greatly improved in the design of contemporary automotive interiors.

Slide 34 - The interior environment poses as many visualization problems with regard to glare.

Slide 35 - The control of unwanted glare from both natural and artificial illumination sources is critical for successful negotiation and navigation of the man-made environment.

Slide 36 - The lack of contrast between the floor and counters in this kitchen creates a problem of visibility of the open dishwasher unit.

Slide 37 - Floors that have barely noticeable shifts in level become an obvious hazard- the difficulty compounded when vision changes occur.

Slide 38 - It is easy to understand how many things may become lost or misplaced when they are confused together without organization.

Slide 39 - Black text on a white ground in this display makes the types of cheeses impossible to distinguish one from the other.

Slides 40-49

Slide 40 - The opacity of the cornea alone.

Slide 41 - Control and Display Panels found among consumer appliances present numerous challenges- and opportunities- to the product designer to realize and consider Human Centered Design.

Slide 42 - Microwave ovens have had an interesting history since they were introduced into the marketplace of consumer products during the mid-1960s.

Slide 43 - The glossy surface on this touch sensitive control panel disappears from view when seen through the empathic lens, simulating the glare seen by the aging eye.

Slide 44 - Sensory Change and the Product Design Response.

Slide 45 - The Design Principal that should be observed to make control and display systems more legible and, hence more useable is called redundant cueing.

Slide 46 - Separation of Groups of Controls permit easier identification of function.

Slide 47 - In the development of this video camera using the advanced technology of read/write photo CDs.

Slide 48 - Redundant Cueing of controls through color and shape coding allows for signaling using both visual and tactile cues.

Slide 49 - A thermal induction cook-top presents significant control and display attributes.
