accelerometer and gyroscope

accelerometer is of the sensor. type_accelerometer type.Return the value of the accelerometer through Android. Hardware. sensorevent.The Unit returned by the accelerometer is the unit of acceleration m/s ^ 2 (meter per second). The values in three directions are Values [0]: X-axis AccelerationValues [1]: acceleration in Y-axis directionValues [2]: acceleration

the same one thing: it performs like shit . for those of you who don't know: I spent the past 7 years being an active ActionScript developer. i'm not what one might call a flash-hater . I 've tried to create simple games and apps for iOS using flash. A game using the accelerometer (which crashed when too much Accelerometer Data came in simultaneously. limiting that datastream kind of went in the wa

PhoneGap: Build a cross-platform APP: phoneGap mobile APP practice, serialization 1 (API in PhoneGap ), Previously, Benbo serialized the book "Building a cross-platform APP: jQuery Mobile APP practice", which is favored by beginners of Mobile development. From now on, the book phoneGap, its twin sister book, has become a big white book. 3.6 what can APIs in PhoneGap do? This chapter mainly introduces the preparations required before the development of PhoneGap. Do you want to talk about Phone

Accelerometer is the basis of the entire iOS screen rotation, relying on the accelerometer, the device can determine the current device orientation, the IOS system has defined the following seven device orientations:typedef Ns_enum (Nsinteger, uideviceorientation) { Uideviceorientationunknown,uideviceorientationportrait,//Device oriented vertically, home button on the bottomUideviceorientationportraitupside

Book DescriptionProfessional flash mobile development: Creating Android and iPhone applications Everything Flash developers need to know to create native Android and iPhone apps This wrox guide shows Flash developers how to create native applications for Android and iPhone mobile devices using flash. packed with practical examples, it shows how to build a variety of apps and integrate them with core mobile services such as accelerometer, GPS, phot

Accelerometer The accelerometer API is used to obtain data from the gravitational acceleration sensor, which is used to develop programs such as games. if (am != null) 　　　 am.Stop(); am = new Accelerometer(); am.ReadingChanged += new EventHandler try//因为启动时，如果出错会抛出异常，所以要用try块来处理。 { 　　　　 am.Start();//开始获取数据 } catch(AccelerometerFailedException e) { } 　 am.Stop()

occurred. Other event passes may be slightly different from touch event passing through a variety of application objects.There are many types of events that can be passed in an iOS app. The most common events are listed in the following table:Most of these event types are passed through the application's main run loop, but some are not. For example: The accelerometer event is passed directly to the application of the specified
