Smart phones: automatically input devices that locate tasks in various ways. Position can refer to the screen position or physical position in the real world.
Smartphone has been used in various ways to locate tasks: for example, continuous indirect translation using a trackpad.
The remote commander enables the individual to use the touch screen on the PDA as a trackpad to control the relative position of the cursor on the remote display.
Continuous indirect translation with speed

The zero joystick controls the speed of continuously repositioning the object.
The zero displacement of the joystick corresponds to the zero speed.
Silfverberg and others. has done an in-
Delve into the equal distance joystick on the handheld device to control the cursor on the public display.
Nowadays, many mobile phones use binary resolution, 4 to 8 directions, and return-to-zero joysticks.
Continuous indirect translation with accelerometer.
The accelerometer began to appear in handheld devices such as samsung SCH s SCH-
Integrated 3 S310 phoneD. acceleration meter
Allow users to scroll (e. g.
By electronic photo album)
Handheld devices by tilting.
Although this technology is used to interact directly with applications on the device, it can obviously be extended to locate tasks in ubiquitous computing environments.
Continuous indirect translation with directional stepping keys.
The position of the object is controlled by using the up, down, left, and right step keys 2-
D. application, 3-D.
In the Blinkenlights project, the user presents a large public display on the side of the building for the arcadeclassic ping-pong.
Each window is equivalent to one pixel on an 18x8 pixel display.
Players connect to the display by calling the phone number.
Press the number 5 on the phone keyboard to move the paddle up and the number 8 to move the paddle down.
Continuous direct translation with camera tracking.

Interaction-based, including tagging interactive GUI elements such as components and dial.
When operating the position and direction of the recorder, the user can locate the graphic slider or the graphic dial.
You can draw an analogy with a classic light pen with a tracking cross.
When the light pen moves to a new position, the cross moves with the pen.
Tracking can be lost if the pen moves to fast, but can be easily recovered by repositioning the pen to the tracking cross.
Madhavapeddy, etc.
Crossinteractions replaces cross-tracking with tagged GUI controls.
Wait in Madhavapeddy.
The location technology mobile phone is responsible for tracking, and the environment is responsible for displaying and refreshing the tracked images.
Other interactions have been created through these role exchanges.
For example, smartphones have been enhanced by laser pointers to suit the positioning tasks described by Olsen and others.
Use the camera in the environment to track the laser.
Continuous indirect translation with camera tracking. The C-
The Blink system allows users to position the cursor on a large screen using a mobile phone with a color screen.
The user runs a program on the phone that quickly changes the tone of the phone's screen and wave the phone in front of the camera installed above the large display.
The displayed hue sequence encode the ID to support multiple users.
The camera places this signal in an absolute position in the camera image to control the sensor on the display.
Discrete direct translation using camera images.
The trajectory of attention is on the screen.
Your goal is to use the cross hair shown on the live camera image on your phone.
To reposition the cursor, you can press and release the joystickbutton while aiming at the desired position with the cross head.
This triggers the tag grid and will soon be superimposed on the large display content of the server.
The grid is used to export coordinate systems independent of perspective, in pixels-
Level accuracy, which is enabled by the special properties of the visual code label.
It can be compared to the classic light pen, when the user clicks the button on the light pen, the position is determined discrete by displaying the raster scan.
When scanning with a pen detects raster, the position of the pen is known due to the tight coupling between the Pen Clock and the display clock.
In Point & shot, the visual label grid replaces the function of raster scanning.
The technology is robust to different display techniques as well as loose coupling between the camera and the display.
In the camera view, point and shoot can establish a coordination system with only one visual label, but the grid is used to increase the probability of meeting this requirement.

There is no obvious visual label.
The camera does not even need to point to the Monitor.
To call the joystick weep function, rotate the joystick button down, which acts as the clutchto, indicating to the system that you are actively controlling the cursor.
Press the joystick button when selecting or dragging.
The mobile phone swayed in the air.
You can loosen the clutch button to reposition your arm, similar to how the mouse relocates on the desktop.
In scan mode, you can ignore the screen on your phone, focus your attention on a large display, and watch the cursor move.
