Aber kein Navigationsger\u00e4t kann helfen, sich zurechtzufinden, etwa bei einer Konferenz: GPS-\nSignale k\u00f6nnen meist nicht empfangen werden oder bieten keine ausreichende Genauigkeit bei\nder Lokalisierung, und digitale Geb\u00e4udepl\u00e4ne sind \u00f6ffentlich kaum zug\u00e4nglich.<\/p>\n                                        <p class=\"translation-block\">Im Projekt <em>topikos<\/em> forschen Prof. Dr. Gerd Stumme und Bastian Sch&auml;fermeier an Methoden, damit sich Nutzer innerhalb von Geb&auml;uden verorten k&ouml;nnen und die Mobilit&auml;t vieler Personen visualisiert werden kann. Ihr Ziel: Die Methodik soll ohne zus&auml;tzliche Infrastruktur auskommen und an jedem Ort eingesetzt werden k&ouml;nnen.<\/p>\n                                        <p>Zur Lokalisierung setzen sie WiFi-Signale ein, die jeder im Geb\u00e4ude vorhandene Router st\u00e4ndig aussendet. Deren Signalst\u00e4rken hinterlassen an jedem ausreichend abgedeckten Ort eines Geb\u00e4udes einen mehr oder weniger eindeutigen Fingerabdruck. Mit Hilfe eines\nSmartphones lassen sich die Signalst\u00e4rken messen\nund mit einer Datenbank abgleichen, um den\nStandort zu ermitteln. Da sich Umgebungen st\u00e4ndig \u00e4ndern, ist es zu aufw\u00e4ndig, solche Datenbanken manuell zu erstellen und aktuell zu halten.\nDaher entwickeln die Forscher Algorithmen, die Datenbanken weitestgehend automatisch erzeugen. Stumme und Sch\u00e4fermeier untersuchen daf\u00fcr unter anderem Ans\u00e4tze, wichtige Orte und ihre Semantik zu erkennen. Diese zeichnen sich etwa dadurch aus, dass sich dort viele Personen mit \u00e4hnlichen Interessen oft und lange aufhalten.<\/p>\n                                        <p>Das Team wird dabei vor viele praktische Herausforderungen gestellt: Neben einer funktionierenden Methodik, die auch robust gegen\u00fcber verschiedenen Sensoren und Signalst\u00f6rungen ist, darf der Batteriebedarf der Smartphones nicht zu hoch\nsein. Und: Die Privatsph\u00e4re der Benutzer darf\nnicht verletzt werden.<\/p>\n                                      <\/div>\n                                    <\/div>\n                                  <\/div>\n                                <\/div>\n                              <\/div>\n                            <\/div>\n                          <\/div>\n                        <\/div>\n                      <\/div>\n                    <\/div>\n                  <\/div>\n                <\/div>\n              <\/div>\n            <\/div>\n          <\/div>\n        <\/div>\n      <\/div>\n    <\/div>\n  <\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Issue: 01\/2019 Mobilit\u00e4t von morgen Indoor Navigation It&#8217;s easy to get lost in big buildings.
