Hi, Is there any way to find, iPhone movement?. I need to know if iPhone is still i.e its not moving then do some thing or else if iPhone is moving(in vertical or horizontal direction) do some logic. Do I need to read accelerometer didAccelerate method. Or there is some other way like reading current location (lat/log) values. [I DON...
Hello All, How to detect the iPhone angle? I mean that when iPhone is straight (i.e) HomeButton is in bottom part, so how to detect 90 Degree from UIAccelerometer Method. CGFloat RadiansToDegrees(CGFloat radians) {return radians * 180/M_PI;}; i try RadiansToDegrees(atan2(acceleration.y, acceleration.x)) but it gives -90 degree angle ...
Hello All, How do i calculate Dip and Strike from iphone. They are used to measure rocks. i have to use compass api how do i get the angle from it. anyone has idea please give me some idea. Thank you. ...
I need to add a shake feature that will refresh my Anroid application. All I find of documentation involves implementing the SensorListener, but Eclipse tells me it's deprecated and suggest SensorEventListener. Anybody that has a nice guide to how I go about creating this "shake controller"? ...
Hi all, I am working on app which is used to display the current G-Force value of a moving car on iPhone. I don't know how to calculate the G-force value using the iPhone accelerometer values. Also, I have to calculate distance and speed using these values. Can anybody help me out to fix this problem? Thanks in advance ...
Hi, have developed an app for BB storm while tilting the device the background image of the app screen does not matches with the screen size, i have tried with the sublayout method public void sublayout(int width, int height) { //update scrren layout based on orientation if(Display.getOrientation()== Display.ORIENTATION_LANDSC...
Hi, i develop application for Blackberry. In Storm 1 (4.7) and Storm 2 (5.0) i need to disable accelerometer in my application. I want my application does not react to the accelerometer, but that does not affect other applications. Its possible? ...
Hello, GLGravity iPhone example showing how to use accelerometer and OpenGL suffers from Gimbal Lock problem. I'm wondering is there any code available using quaternion rotation instead of Euler angles? Any help will be greatly appreciated, I'm struggling with this from a long time without having a success ... ...
I am trying to get the accelerometer to detect shakes in a separate view and the accelerometer method does not get called? When I place code to set the accelerometer attributes in the controllers viewDidLoad method and add the ......didAccelerate:(UIAcceleration *) acceleration in the implementation file for the controller shakes are de...
I have an app with a tab bar, and nav controllers in each tab. When user shakes the device, a UIImageView appears as a child view in the nav controller. But the UIImageView must contain a special image, depending on the device's current orientation. If I write just - (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrienta...
Is there a special method to get iPhones orientation? I don't need it in degrees or radians, I want it to return an UIInterfaceOrientation object. I just need it for an if-else construction like if(currentOrientation==UIInterfaceOrientationPortrait ||currentOrientation==UIInterfaceOrientationPortraitUpsideDown) { //Code } if (current...
So apparently it is possible to keep the processor going processing stuff while the screen is locked, as indicated here: http://stackoverflow.com/questions/1551712/running-iphone-apps-while-in-sleep-mode However, after testing with the example code, UIAccelerometer will just stop giving value as soon as the device is locked pronto. Is ...
hi, has anybody already programmed a iphone compass heading tilt compensation? i have got some approaches, but some help or a better solution would be cool! FIRST i define a vector Ev, calculated out of the cross product of Gv and Hv. Gv is a gravity vector i build out of the accelerometer values and Hv is an heading vector built out ...
I am planning to develop an accelerometer based mouse on the android platform. the mobile device which i plan to use is htc nexus one. the cursor should move as the mobile is moved is space. will that be difficult compard to movement wrt gravity? ...
My application goes back and forth between Portrait and Landscape. I have all of my content(labels, uiimageviews, uilabels) lined up to relocate for both orientations. However, the only change when the device is actually rotated. When I cycle between tabs after it has been rotated it just shows up autosized and not the way I have it s...
Hi, I am using the accelerometer to move a few UIImageViews around the screen, at the moment the accelerometer only works when a NSTimer is at 0, this is fine. I would also like to make the accelerometer stop again when a different function happens. here is my code at the moment: -(BOOL) accelerometerWorks { return time == 0; } -(voi...
I have an iPhone 3.1.3 app which has only 2 methods of input in its main view. It has an info button to switch to a flipside view, and the only other input it takes in the main view is accelerometer movement. I want to switch off the accelerometer input when in the flipside view but haven't been able to find out how. I have the main vi...
i have used accelerometer.. but what should i do to detect hosrizontal shake of device? Thanks in advance.. ...
Hi all, At present i am working on hal part of sensors in android sdk, we are using 3- Axis BMA-150 Accelerometer sensor to get acceleration values with respect to X,y,Z Axis, I want to know whether this sensor will give o/p directly in SI units by using some calibration techniques or what ? , and i noticed that in sensor.c file they me...
I am looking at using the accelerometer as an input channel for controlling a game on the Blackberry. However, I only want to respond to it when the user makes a violent motion to the left or the right. So my question is: what is the range of input to expect from a user holding the device in their hands and what threshold should I set ...
