Query-Point® is a directory into which “advertisers” of products, services, places or celebrities may place information and set the range of the availability of that information based upon whatever distance makes the sense in terms of being obtainable. We call this information a listing The app is the gateway to retrieving the information. An app user requests the information using a “keyword”, and may then listen to the response placed into the directory by the advertiser The system is GPS based. Real estate signs, local storefronts, billboards and bus benches and historical markers all have a range of operation of 1200-feet from the sign or storefront. This is in effect a 2400-foot umbrella within which the system will operate Government signage has an operational range of 2200-feet, or an umbrella of 4400 feet. Distances go up dramatically from there Hyper local geo fence promotion, which could include schools, may have a 4-mile radius of operation Ads on a city bus might use a 15 mile radius (A 30 mile umbrella) to allow information to be requested anywhere along a route Large local businesses, in particular ones using a lot of trucks with their name painted on them, might choose a 50-mile radius of service. Radio and local TV advertisers might choose a 150-mile radius of service to get the coverage needed where-ever the ad is heard. Each “advertiser” has a pin on the map found in the app which may lead to acquiring the same information as would be gained when within proximity of the fixed point Each listing has a QR code that takes people to the same information in a universal format that does not require use of the app Query-Point® is a directory that allows consumers using our app to “pull” Internet based information from specific entities. Unlike search engines, the entity being requested provides the information the user receives How it Works As the app user comes “in range” of the enabled sign the user is able to push the microphone button and say the keyword(s) found on the sign that triggers the system to provide information. Usually this action is stimulated from viewed signs that are nearby. The app user says what is written on the sign or heard over the air, (the keyword(s)) into the app and the system responds with immediate audio information, and supplemental information through the app. The supplemental information may include web links, pictures, contact information and video. The information is placed on the system by or on behalf of the stakeholder or advertiser We are all about safety. Entities also get an icon on the map found in the app. Another safety precaution is the use of short-cut keywords by category that gather the information from every listing that is within the users range. For example sometimes it is hard to get the name from a real estate sign, in which case the app user may grab the same information by saying “Hey Property”. This will return any property items within range of the app user Saying “Hey Local” will return any of the local entities with range of the user. These could be local businesses but also nearby churches and schools. Saying “Hey Marker” will retrieve information from historic markers if listed in out directory. Government services, including zoning signs, public works signs, and items such as buildings and parks, will respond to “Hey Government”, up to a range of 2200 ft. Any of the items with a range based in miles will respond to “Hey Info” Cost The app is free to users. For advertisers, the basic service can be free for many categories Information and Privacy App users are anonymous and they will not receive pop-up ads in their emails or while browsing. Paid advertisers have on their dashboards the record of the time someone queried their sign. They are provided with no other information. Visit https://www.query-point.com to learn more.
