Positioning in digital assistants
Recently we were asked to do a little research about mobile digital assistants and positioning in buildings.
First we looked at GPS (Global Positioning System), as Japan and Korea do a lot of interesting stuff with gpsOne mobile phones. The problem with GPS is that it isn’t very precise – the range is something between 5 and 50 meters.
Next idea was bluetooth and still is.
In the meantime I asked Tumasch Reichenbacher who did a presentation about SVG in mobile situations at the last SVG Open Conference.
He told me to check out the latest Ericsson Review and gave me the link to the one, he mentioned in his presentation last year.
He added:
Natrlich gibt es fr den Indoor-Bereich Positionierungslsungen mit IR-Sendern. Soviel ich weiss ch we, gibt es da auch schon Pilotprojekte in Museen bzw. auf Messen. Vielleicht wre da auch das Projt Saimotion interessant.”
