OzHub, the Macquarie Telecom-led cloud computing alliance, has come down firmly on the side of Optus over the copyright controversy surrounding Optus TV Now, warning that any moves to change the law "risk branding Australia a global luddite state."
Australian iPhone developer Graham Dawson has followed up his popular Oz Weather app with a new augmented reality app with a difference, Sun Seeker.
Rather than displaying geo-located point-of-interest data in a camera overlay view, as most of the new apps in this newly emerging sector do, it instead displays an astronomical view of the sun's location in the sky - complete with a pointer guiding you to the exact location of the sun, regardless of how dull or overcast the actual weather may be, or for that matter if you happen to be indoors in a room without any natural light.
In addition to its here-and-now sun-seeking capability, it also displays the entire daily path of the sun overlayed onto your surroundings, including its rise and setting points for today or for any day of the year, with markers showing the Sun's position at each clock hour of the day.
It also has a flat compass type view, highlighting the daytime/nighttime sectors of the sun's daily path, as well as showing the full diurnal solar path as a hemispheric projection, and lists extra details regarding exact sunrise and set times, and daylight duration amongst others.
Although this app may be appealing as an iPhone "show-off" to some, and an intriguing new technical instrument for others, there is a range of practical situations in which it could prove especially valuable.
* Real estate agents & buyers can find the sun-exposure of any property they are viewing - and determine exactly how much sun the property will get throughout the year, and when and where it is blocked by surrounding buildings or hills. and which rooms get direct sunlight at which times of day.
* Gardeners and landscapers can find the varying daily and seasonal sun exposure of different positions within their allotment, and hence be able to more intelligently match plant types to their exact locations.
* Photographers can determine when the shadow direction and length is most ideal for their intended subject.
* Architects can get an accurate idea of light variations throughout the day and year for any sites and buildings they may be designing.
As with other augmented reality applications, Sun Seeker requires an iPhone 3GS, as this is currently the only model that includes the built-in digital compass that’s necessary for augmented reality.
