| Decrease reliability costs by improving accuracy on the automatic tracking devices |
The first few times a user views a sleep or step log, inform the users on that log page that if the numbers look wrong, sensitivity setting adjustments can help improve accuracy, and direct the user to those settings. |
| Decrease time and effort costs by improving navigation |
In an initial start-up video, show users that the navigation bar changes in certain contexts and where they can always click to return to their homepage. |
| Decrease time and effort costs when adding to the food tracker log |
An introductory video should guide users step-by-step, through adding a food, deleting accidental errors without restarting the log anew, entering a unique food, and reusing frequently consumed foods. This video could be available for reference when users add their first entries for users to follow along with in real time. |
| Decrease learning costs and increase potential uses by gradually easing users into the format and into less commonly explored features |
Ease users into learning the many different trackers and settings. For example, for the first few days of logging in, new videos or pop-up labels could explain features, starting with the most important on the first days and continuing with less critical features on later days (e.g., first activities and foods, then custom trackers, then greeting changes). |
| Increase personal benefits by improving communication of usefulness with older adults |
Include older adults in advertisements and market on media streams older adults frequently encounter. Explain how older adults can personally benefit. For example, for older adults monitoring diet intake (e.g., sodium or sugar), explain that the calorie tracker also records nutritional values. |
| Decrease financial costs and make benefits more tangible |
Allow free trial-use periods, enabling older adults to know that they will like the technology prior to buying and enabling older adults to experience the benefits for themselves. |
