Introduction

Intro (Slide 1, Alex, 5 sec)

Hi everyone, this is team Hyperdash. And all our team members are listed on the slide.

Overview (Slide 2-3, Alex, 20 sec)

Our project is an Emergent Fall Rescue Network for the Elderly Living Alone.
Through an app, the network will send rescue requests to volunteers once an elderly fall has been detected nearby. The app will also guide and facilitate the volunteers to support the elderly until the arrival of the medical staff.
In this stand up, we will introduce the following works we have done.

Review (Slide 4, Evelyn, 40 sec)

After the last stand-up, we have done a more in-depth study on these issues:

• The problem space/volunteer motivation/existing solutions were first researched
  For volunteers, we first searched the relevant literature and researched the problem space/volunteer motivation/existing solutions.

• To further confirm, a survey and interview was conducted on volunteer willingness and motivation
  To confirm the reliability of the research, we conducted surveys and interviews on the willingness and motivation of volunteers.

• Then the psychological state of the elderly when receiving help was researched
  Then in order to have a more comprehensive understanding of whether our design is suitable for the elderly, we researched the mental state of the elderly when they received help, and interviewed them.

• To further confirm this, interviews were conducted on the wishes of the elderly and who they were willing to accept help from

• Low fidelity prototype evaluation (heuristic evaluation) among potential volunteers and experts
  Finally, we evaluated the low fidelity prototype among potential volunteers and experts (heuristic evaluation). And used the main feedback when designing the medium-fidelity prototype.

Research Outcomes

Literature Research (Slide 5-6, Kai，30 sec)

The literature survey is divided into four parts. These studies show that falls in the elderly have become a social problem that cannot be ignored. And for volunteers, it is necessary to pay attention to their psychological changes before entering and when they are in the rescue organization. For the elderly, whether they need help, which they expect to help them. What types of help they want are the things we need to investigate. The problems we found here are implemented in the survey and the interview.

Interview and Survey Analysis (Slide 7-11, Eric, 30 sec)

• What we found out from the research survey and interview
  According to the result analysis of interview and survey, we found that:

• The elderly prefer to let the people close to them take priority to rescue
  Even getting help from nearby volunteers is of less priority but they would be welcomed if no relative or friend could arrive in time. Otherwise, older people would rather get help from relatives and friends as they know those people.

• As the severity of the fall varies, users are concerned about the ability of the rescuer to rescue them
  The professional skill should be trained and assessed since volunteers are going to deal with various complicated situations. In addition, since older people are vulnerable and secondary injury may occur if the volunteer takes inappropriate action.

Evaluations

Prototype evaluation (Slide 12-14, Kai, 1 min)

Introduction of the Prototype evaluation method and presentation of the results, describing the main problems found therein

• User instructions are not detailed enough and volunteers are concerned about receiving rescue missions they are not capable of performing
  We use heuristic evaluation for our low-fidelity model. This is because the evaluation method is a thorough assessment of a product’s user interface. The evaluation process is conducted against a predetermined set of usability principles known as heuristics. Since the appointment of 5-8 evaluators allows the review results to be more than 80% accurate, we invited 6 evaluators. Here are the results. On the left, you can see theirs' choices, and on the right, you can see the comments they made. In addition, the last column shows additional advice. We summarized the comments and concluded the most important issues: User instruction is not detailed enough and Volunteers worry about receiving rescue work they are unable to handle.

Solutions & Medium Prototype

Solutions (Slide 15-16, Evan, 30 sec)

• Grading of the severity of falls in the elderly
  As the severity of the fall of the elderly is different, so are the rescue abilities of the volunteers. We decided to add a grading system to our design. It will classify volunteers based on their rescue capabilities. Then, according to the severity of the elderly fall, the system will send rescue requests to qualified volunteers.

• Add customizable rescuer priority
  According to the survey, the elderly and their families prefer to have their relatives and friends as the priority rescuers. So we designed a feature for the elderly to choose the priority of rescue. The elderly can make a priority choice among the rescue groups, and when they are in danger, the system will give priority to notify the first rescuer.

• Strengthen the rescue capacity of volunteers
  After a user becomes a volunteer, we will grade them based on their rescue experience and recent rescues. Volunteers are assigned jobs that match their level, and only volunteers who have watched a certain amount of video instruction and passed the assessment are allowed to participate in rescue work.

• Familiarize volunteers with the process (how to become a volunteer and understand what level of rescue you can perform)
  Offer the volunteer a platform to get access to the progress of how to become a volunteer who is qualified and certificated by an official medical institution, so that they can distinguish which level of the situation they can handle easily.

Medium Prototype (Slide 17-24, Gavin, 1 min 5 sec)

Showing the parts of medium prototype that we have modified for Section 4

• Login screen login and registration page (Slide 18)
  On the entry page, we changed the background color and button style of the sign in and register pages to make it consistent with the entire app structure.

• Home & Tutorial Page (Slide 19)
  On the homepage, we added a search bar, and divided a rescue guide into a video guide and a picture text guide. In this way, it is convenient for users to use the search bar to find the guidance they need, and can choose the video or picture text combination according to their own preferences.

• History Page (Slide 20)
  On the history page, we changed the original history book to a file storage page. After clicking the detail button, users can see the current situation and historical information of the people they once rescued. The search bar and filter to this page to facilitate users to find the rescued elderly they care about.

• Personal Profile Page (Slide 21)
  On the personal profile page, we integrated the qualification part to show which level of rescue volunteers are qualified to participate in, and deleted the occupation display, because we think occupation is not necessary. On the personal profile editing page, we added an info icon next to qualification, and clicked it to pop up the qualification details.

• Navigation (Slide 22)
  On the navigation page, to make it easier to use, users now can choose to change the driving mode to the destination, and can also choose different driving routes and check the time and distance needed.

• Video Meeting & Float Call Icon (Slide 23-24)
  The call function has been upgraded. Now the volunteers can hold a video meeting with the medical staff and the family member. Besides, the calling interface can be minimized as a float call icon. So that the volunteers can escape the shackles of the call interface and move freely to check other information they need.

Changes & Future Directions

Changes & Future Directions (Slide 25-26, Evan, 20 sec)

• Designing the interface for selecting priorities on the elderly side
  Provide fixed choices for the elderly who wanna call for help, such as their family, friends, neighbors or strangers, so that they can choose the priority of who they wanna call for help themselves.

• Building rescue scenarios with Unity
  We plan to build a scene in Unity to provide an immersive rescue process for volunteers. Therefore, besides the app interface, they can also experience what will happen in real-world rescues. The process starts with the elderly fall and ends with the arrival of medical staff.

• Medium Prototype Evaluation
  After completing the medium-fidelity prototype, we will conduct a formal evaluation. We will take two aspects of evaluation. One is Time on Task and Think aloud to evaluate the functionality and how easy it is to use Prototype. The other is the analytic evaluation method to allow developers/designers to act as users to analyze all aspects of the application, so that we can get clear and intuitive information.
