Getting Your Student Started With iPhone GPS A guide for Orientation and Mobility Specialists by Joe Dlugo, COMS / TVI Updated April 2016 Welcome! This day in age it’s hard not to find O&M specialists talk about iPhone GPS. With a half dozen or so blindness-specific GPS apps available for an affordable price or free, the barriers to getting a GPS into your student’s hands are diminishing. Over the years I’ve used various iPhone GPS apps with my students and have learned a lot about what they can and perhaps more importantly, can’t do. They certainly are an excellent tool when used correctly and with the appropriate expectations as to their capabilities. This guide to getting your student started with iPhone GPS was developed to give students the best chance of early success in using the app in order to encourage further and more advanced exploration with this technology in the future. This is a work in progress, and I always welcome collaboration. If you have a suggestion to improve this, kindly contact me to let me know at my e-mail: [email protected]. -Joe Dlugo, COMS / Teacher of the Visually Impaired Contents I. II. III. IV.

Here are some skills I look for when determining if GPS is appropriate: General knowledge of how to operate an iOS device Knowledge of Voiceover is preferable, but you can also use GPS instruction as a motivating way of learning Voiceover The student has flexible thinking patters / doesn’t frustrate easily if their expectations aren’t met Good O&M problem solving skills. Generally accurate knowledge of distance units such as yards, meters, miles Knowledge of cardinal directions Is able to work with clock face directions (1 o’clock, 2 o’clock…) II. Essential iPhone GPS “gear” iPhone Download the iMove app from the App Store (free!) A loud bluetooth speaker connected to your iPhone (it gets mighty loud out on the street and the iPhone speaker is not loud enough to compensate. Something to mount the speaker on (I use a Motorola Roadster 2 mounted to a backpack strap) Activities III. Optimal Settings for the Beginner It’s important before you start to set your GPS in a way that is optimal for the beginner. I recommend adjusting the default settings and using those I have listed below. These will allow for a reasonable amount of Point of Interest (POI) and address identification without filling your student’s ears with excessive amounts of audio clutter. Go to settings (the cog in the upper right corner of the screen) Address Distance: 30 yards Time: 30 seconds City: Off Bearing: Off Course: Off Speed: Off Read Automatically: On Points of Interest Distance: 100 yards Repeat: 30 seconds Read automatically: On Notes Distance: 30 yards Repeat 10 seconds Read automatically: On System Prevent the screen lock: On Background execution cap: On *See next page for screenshots of the settings menu Optimal settings for the beginner GPS user (visual): IV. Activities 1. Define GPS Many times our students hear the acronym “GPS” but don’t know what it stands for. It’s important to know the name, but also a little bit about its history and how it works will help alleviate some confusion later on. 1. Define the term GPS The Global Positioning System (GPS) is a space-based navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.[1] The system provides critical capabilities to military, civil, and commercial users around the world. The United States government created the system, maintains it, and makes it freely accessible to anyone with a GPS receiver. (Wikipedia) 2. Main Concepts to Know: GPS Acronym: Global Positioning System Navigation Satellites What is the minimum number of satellites are needed at one time? Who runs the GPS system? What do you need to use it? How much does it cost to use GPS (free for the service, but you might pay for apps/data plan? 2. Demonstrate the iMove GPS It is important the student has an idea of what they are working toward, so a short demonstration of only the most basic “Around me” capabilities of the GPS is fitting at this point. Using the GPS to find your location, select a POI (Point of Interest) category, acquire a list of nearby POIs, and finding the POI’s address and phone number is a good start. Directions for demonstration: 1. Turn on Voiceover 2. Select/open iMove 3. Select and read out your Location 4. Go to Around Me 5. Select the “i” icon (More Info) to the right 6. Select Restaurants, Bars and Catering 7. Select the <Back button to return to the home screen 8. Select Around Me 9. Swipe through the Points of Interest to show all the nearby Restaurants, bars, and catering 10. Select one of the Points of Interest 11. Select Address to read out the address 12. Select Phone Number to read out the phone number. 13. When you are finished, select Back (twice) to return to the home screen Visual screen-by-screen directions are found on the next page. 1.Readout Location 4. Select Category 5. Select Back 8. Read address 2. Around me 3. Select More Info 6. Select Around me 9. Read Phone# 10. Back (twice) 7. Read POI list 3. Accuracy Lack of accuracy can be the most frustrating concept for a student who is learning GPS for pedestrian pursuits. it is important that the student has a grasp on what accuracy is and how to handle its shortcomings. 1. Define Accuracy: ✦ Accuracy - the quality or state of being correct or precise 2. Read to student: ✦ GPS on the iPhone is designed for use by fast-moving vehicles with sighted drivers that can cover hundreds of feet in seconds, not for blind pedestrians who can only cover dozens of feet at best and cannot tell what is in the distance. Therefore low accuracy is very evident when using a GPS for a walking route. 3. What are the Impediments to accuracy? ✦ Too few satellites in range of your GPS ✦ Tall buildings, such as in big cities - the signal bounces off of the buildings or is blocked by them ✦ Thick clouds ✦ A thick tree canopy ✦ Hills or mountains nearby - the signal from satellites can be blocked by these 4. Create an activity to solidify the concept of accuracy: ✦ Show the student a dartboard, have them play guess a number, or discuss their score on a recent test to solidify the concept of accuracy. Put something in the way of their dart throw or confuse them when guessing a number to reduce their accuracy. 5. Demonstrate: Demonstrate how the iMove GPS measures accuracy. Turn on Voiceover and select the Location at the top. It will read out your current location with an accuracy reading of high, medium, or low. Have the student repeat the exercise and tell you what the accuracy reading is. 6. So what is the iPhone GPS actually good for? ✦ Telling us what’s nearby ✦ Generally where we are ✦ Reassures you you’re on the right path ✦ Telling lists of directions 7. What is the GPS NOT good for? ✦ Giving turn by turn directions as you walk ✦ Locating very specific, small landmarks ✦ Replacing an O&M specialist! QUIZ!!! • • • • • What is accuracy? How does iMove measure accuracy? What is the iPhone GPS good for? Name some things that can impede accuracy? Is GPS good for giving turn by turn directions to a place you’ve never been to? 4. Using the Around Me feature This is the student’s first time to get their hands on the GPS. It is basically repeating the demonstration you gave in step 2, but now you are instructing them as they go about the activity. Expect that you may have to troubleshoot voiceover technique. 1. Repeat the steps in Activity 2. (Above) 2. Assign homework — If your student has an iPhone, have them use the iMove app at home to select a POI category and then write the top five results in relation to their house. Bring to the next lesson. 5.GPS Lingo As you’ve probably discovered in the previous exercises, there’s a bit of shoptalk associated with using a GPS. Terms such as POI, bearing, course, etc. might be new concepts and it’s important to ensure your student understands them before proceeding further. 1. Definitions of common GPS terms: ✦ POI - Acronym for Point of Interest: A specific place, such as a store or landmark that can be accessed by your GPS ✦ Cardinal direction - N, E, S, W ✦ Bearing - The cardinal direction you are facing ✦ Course - The general cardinal direction you are proceeding in over a period of time ✦ Speech Note - A POI that you’ve created on your GPS app. A speech note is set by recording your own voice, and if the GPS is accurate, it will read you that speech note every time you pass the point where it was set. ✦ Text Note - Like a speech note, but set by typing in text instead of speaking into your phone. ✦ Address range - the addresses that are found in a specified space. Usually the GPS reads address ranges in regard to a block you are walking along. ✦ Yard - 3 feet (the iMove GPS gives distances in yards). 2. Quiz!!! Have the student study the above definitions and quiz them on it next lesson. 6. Setting a Speech Note If you’re familiar with the Trekker GPS, then you know the power of speech notes. It allows you to input various landmarks that aren’t identified by the GPS and will speak them back to you when you pass them (if the GPS is accurate). Your students will find this part fun. 1. Demonstrate setting a speech note ✦ Go to a location where there is a significant landmark that you’d like to make a POI ✦ On the home screen select New Speech Note ✦ A black screen with a microphone icon will pop up quickly - quickly say the name you wish to call the POI. This will be the recording that reads back to you ✦ Press the screen after you’re done talking ✦ You will be taken to a screen with some options. Select Play audio comment. ✦ If you are satisfied with the quality of your comment, select Save and you will be brought back to the home screen ✦ Now walk far away from your speech note, maybe a block or two. Return to the location where you set it and see if it plays back (in times of low accuracy it does not always play back). 1.Select New Speech Note 2.Quickly say the name of your POI, tap screen when finished talking. 3.Playback what you recorded 3.If you are satisfied, then select Save 2. Have student set a speech note ✦ Allow the student to choose a location in which to set a speech note. ✦ Repeat the above steps, assisting the student where necessary. ✦ If the speech note does not playback in the correct spot, make a point to discuss accuracy and how it is not good to rely entirely on a GPS for orientation. 7. Going for a POI Walk Now that you’re out and about setting speech notes, it’s time to add in a bit more functionality. Now you’ll go on a walk in a busy area of town with the GPS set to a specific POI category. This essentially repeats much of the previous step “Use the Around Me” feature, but now it’s done while you’re moving. This creates a different experience because now the GPS will alert you of the POIs you pass. 1. On your walk ✦ Select a POI Category of something that is common in the area you will be walking (usually restaurants, pubs and catering is the most commonly found POI in urban areas) ✦ Simply walk down street… ✦ If you have applied the suggested settings stated on page 2, then anytime a restaurant, bar, or catering establishment is within 100 yards or less, the GPS should alert you of its presence ✦ Every so often, stop and select Around Me. Have your student notice that the distances from the POIs change as you move. 2. Get more information about a specific POI ✦ After your student has had the GPS read them several POIs, ask them to find more information about one of them by selecting Around Me. ✦ Have them read the address, phone number, and if there is a website listed. 8. Using Maps Navigation Turn by turn navigation, albeit often unreliable, is still a useful feature on GPS. When used in conjunction with excellent orientation and mobility skills, it offers the traveler added reassurance they are on the right path. This activity is best done in the same environment as the previous activity, Going on a POI Walk. This will use the student’s familiarity with the environment as an aid in understanding what the Maps navigation is telling them to do. I often do the two activities together on the same lesson. 1. Activate Google Maps navigation ✦ After your student has become somewhat acquainted with the POIs in a certain area, it’s time to use the Maps app navigation feature. ✦ By now your student should know how to locate a POI by using the Around Me feature, and select the POI to arrive at the address/phone number/website screen (see previous activity). ✦ Walk about 2 or 3 blocks from a desired POI. Use the Around Me feature to locate the POI. ✦ Select the POI and then on the Address/Phone/Website page, select the address. This will activate the Maps app. ✦ In the Maps app the route will show up visually and it will read your current location. ✦ At the bottom of the screen select Start For your first few routes, it’s best to use a simple straight line route. The student will not have to concern themselves with navigating turns and intersections and can instead concentrate simply on arriving at a destination. IV. Moving On These lessons only scratched the surface on iPhone GPS. There are many more things to learn about! If you wish to explore further these are additional skills for your student to master: Adjusting settings Setting text notes Settings for speech/text notes Creating a route Assigning notes to a specific route Sharing your location Try and compare other apps such as Sendero LookAround, BlindSquare, Ariadne GPS, The Seeing Eye, or the upcoming iOS version of Nearby Explorer from APH ">
