1 Global Positioning Systems and the Traveler with a Visual Impairment: "Who?" "What?" "Where?" "Why?" and "How?" Craig L. Phillips, MS Ed. COMS December 13,2013

2 Berthold Lowenfeld Blindness imposes the following limitations:  In the range and variety of experiences  In the ability to get about  In the control of the environment and the self in relation to it. (1948) Craig L. Phillips, MS Ed. COMS2December 13, 2013

3 Ehresman’s Theory of Relativity “You are only as INDEPENDENT as your relatives ALLOW you to be.” Paul Ehresman Craig L. Phillips, MS Ed. COMS3December 13, 2013

9 Signals travel by line of sight – Can go through clouds, glass, and plastic – Cannot go through most solid objects such as buildings and mountains December 13, Craig L. Phillips, MS Ed. COMS G LOBAL P OSITIONING S YSTEM 101

10 Three (3) satellites to calculate – a 2D position (latitude and longitude) – and track movement Four (4) or more satellites to calculate – a 3D position (latitude, longitude, and altitude) and track movement December 13, Craig L. Phillips, MS Ed. COMS T RIANGULATION

11 Device Considerations “The difficulty or simplicity of learning how to use a system must work for the student first and the teacher second.” Mike May It’s not about you… It’s not about you… It’s not about you… December 13, 2013Craig L. Phillips, MS Ed. COMS11

21 Four Stages of Learning Unconsciously Incompetent Consciously Incompetent Consciously Competent Unconsciously Competent Craig L. Phillips, MS Ed. COMS21December 13, 2013

22 Begin at the Beginning… Start with the component parts – Assemble/Disassemble Orient to the device Follow with the key describer mode Talk About GPS limits/parameters Movement versus static position December 13, 2013Craig L. Phillips, MS Ed. COMS22

23 Begin at the Beginning… Start with the familiar Then walk, listen, and reference – Learn the language – Repeat the message – What is the information… – Where is it provided… December 13, 2013Craig L. Phillips, MS Ed. COMS23

24 I Say Tomato… What it is… Minnesota Olathe Lenexa Belleview Panera Chipotle Rosehill Belinder Pflumm What it sounds like… Minneysotaa Ahlith Leneexaah Believeyou Pannerra Chipitil Rossahill Beelinedeer P F L U M M December 13, 2013Craig L. Phillips, MS Ed. COMS24

25 Mapping StreetOpen Area December 13, Craig L. Phillips, MS Ed. COMS

26 Landmarks/Waypoints Street and Open Area Mapping – Know where you are – Multiple landmarks can be set at the same time/same spot. – Always set a landmark at the beginning of a route. Always set a landmark at the beginning of a route. Always… Craig L. Phillips, MS Ed. COMS26December 13, 2013

27 Landmarks/Waypoints Pair with physical reference points Label noun first, then adjective – “Smith High School, East Door…” Address entry results December 13, 2013Craig L. Phillips, MS Ed. COMS27

28 Landmarks/Waypoints Nurture environmental literacy. Fill in the gaps to develop the gestalt of the area. Set before and after hazards, headaches, and irritations. Practice renaming, deleting, and unsetting as a destination. December 13, 2013Craig L. Phillips, MS Ed. COMS28

29 Point of Interest = POI Point of Interest Preset on Maps – TeleAtlas – NAVTEQ Use POI rich environments to begin instruction Craig L. Phillips, MS Ed. COMS29December 13, 2013

30 The Virtual Open Doorway Incidental information results in incidental learning and control Nurture environmental literacy Part to whole scheme Craig L. Phillips, MS Ed. COMS

31 Point of Interest = POI Craig L. Phillips, MS Ed. COMS31 Where is the “spot?” December 13, 2013

32 Routing Modes Pedestrian – Distance parameters Motorized – Time parameters December 13, 2013Craig L. Phillips, MS Ed. COMS32

33 Routing Reliability Self-created routes Landmarks and Waypoints POIs Address Entry December 13, 2013Craig L. Phillips, MS Ed. COMS33

34 Sources of GPS Error Signal slows as it passes through the atmosphere Number of satellites visible, terrain, electronic interference, or sometimes even dense foliage can block signal reception Signal multipath occurs when the GPS signal is reflected off objects such as tall buildings or large rock surfaces before it reaches the receiver, i. e. “the Canyon Effect.” December 13, 2013Craig L. Phillips, MS Ed. COMS34

35 Problem Solving Always warm up the device. Reset… Routing Hiccups – No GPS coverage – Turn back – Off route – Silence December 13, 2013Craig L. Phillips, MS Ed. COMS35

36 Teaching Considerations GPS usage demands solid fundamental O & M skills for the final +/- 50 feet. Everything is relative. Context clues/concepts must be practiced. – Organizational parameters – Time and distance – Solicitation of aid – Don’t tell…question. Craig L. Phillips, MS Ed. COMS36December 13, 2013

37 A GPS device is a where and when tool... December 13, 2013Craig L. Phillips, MS Ed. COMS37 Teaching Considerations

38 December 13, 2013Craig L. Phillips, MS Ed. COMS38 Teaching Considerations Much better…

39 Teaching Considerations Preview routes for “blackholes.” Take a cheat sheet on lessons and use it. Use multiple SD cards. Practice with the settings menu Earplugs and headphones are not recommended when traveling. Assume nothing and be open to learning. Craig L. Phillips, MS Ed. COMS39December 13, 2013

40 40Craig L. Phillips, MS Ed. COMS Showing is better than telling… it’s about doing. Teaching Considerations

41 Have your student show you and others, especially relatives. Inservice parents, teachers, and classmates. Encourage borrowing. Get lost on lessons. Motorized guidance Craig L. Phillips, MS Ed. COMS41December 13, 2013

58 FYI… FYI… “I feel like I'm "cheating" somehow, when I don't have to keep track of what street is what, where it's located, what direction I'm heading, etc... it frees my mind up to concentrate on other aspects of orientation...and then, listening to the GPS as I'm riding in a car, realizing the breadth of this world that is outside my car window I have heretofore never gotten to interact with…amazing, simply amazing.” KM age 39 Craig L.
