就輔員所關心的

他們需要提供怎樣的學員

• 大部分學員已經對仁愛醫院已經熟悉
• 記憶功能較差
• 能使用PDA手機，執行拍照工作(我有擔心他們沒辦法完成照完QR code需要將程式關閉)

實驗的方法初步構想

• 單一學員需要走三次
• 1st，就輔員帶領
• 2nd，在沒有輔助工具到達目的
• 3rd，以WADER方式進行
• 如果沒有輔助方法，學員第一次來到陌生地方如何到達目的地
• 就輔員帶領
• 寫下文字敘述，有地圖輔助

實驗日期

• 初步訂於12月
  

WADER Experiment design-fixed

• 現場訪查
• 時間：實驗前幾天
  
• 目的：尋找合適實驗路徑，關鍵點位
• 方式：照相紀錄
• 人數：2 人
• 器材：照相機

• 設定路徑
• 目的：決定哪種路徑適合本次實驗
• 討論一個目的或多個目的地
  
• 路徑的長短
• 取決於可以參加的學員數
  
• 多人時可每人走單一路線
• 少人時可設計一人嘗試多條路徑(多次實驗)
  
  
• 設備準備
• 如距離超出Wi-Fi可以使用，需要用3G取代
• 故前製作業需拉長，需要測試網路，拍照，設定QR code放置點
• 最多一天工作天可完成

• 控制組
  

  • 目的：建立baseline 資料，在未使用QR Code 情況下，是否可以抵達目的地。
  • 方式：學員以沒有輔助工具下，走到指定目的地
  • 人數：依就輔員可以提供的人數器材
  • 器材：無
    
    
• 就輔員訓練
• 目的：教導就輔員使用WADER
  
  
• 輔助人員
• 目的：可事後仔細觀察探討紀錄遺漏之處
• 人員
• 錄影(一名)
• 紀錄(一名)
• 計時
• 學員基本資料，病症
• 就輔員
• 協助學員突發狀況
  

REF:Indoor Wayfinding: Developing a Functional Interface for Individuals with Cognitive Impairments

New found research from University of Oregon

Homepage of Professor Stephen Fickas

SRC possible questions

Why not use RFID?
Most the people own a phone with a digital camera.

Could you give a brief introduction of your research?

explain:
for who?Why for them.
Most of the people with cognitive impairment can have some regular jobs, but sometimes they can not travel on their own because the part of damage of their brain. The need someone to remind them.

The architecture figure.
PDA , Server , QR-code.

Could you explain what is the deviation recovery?
We can not expect all the people can follow the QR code.
So we must have some reminder for the user.
The count down process of the picture will be execute when the expected next QR code is not shot.
When the wrong QR code is shot, the navigation picture will guide you back to the right way to your destination.

Could QR codes be seen easily?
The code can be resize to any scale. If the place is allowed. OK, if the men can't not find the QR code, the caregiver can find out in the google maps when the point keep staying in the same place.

It's not clear when the indoor position is shown on the google maps.
This a problem. If it's in indoor, the map need a special design in more large scale.

Are you sure that people with cognitive impairment can use this device?
Our device is focusing on the those need helps. We are trying to cost down everything that make them affordable. QR codes are so easy to deploy comparing to sensors. I'm not very sure that it can work for everyone. But we can try to find out the problem when the users and caregivers give feedback. Fortunately, we have a long relationship with a hospital in Taiwan. The deeper experiment can be continued in next month. Technology sometimes is not easy to find patients for test. The privacy is a big concern.

I feel pressure

It's not fun when someone is going to question me.
And I need to be compared with someone.

Assessment

• six high school students with moderate cognitive disabilities
• poor coordination
• slight visual acuity
• chosen with the assistance of the teacher
• 40-80IQ (DSM-IV )
• 16~22
• task
• assembling a plastic glider model
• eight step script(image and voice prompt)
• demonstrate
  
• each student successfully completed the task
• users were able to learn and use the basic functionality of the handheld interface
