Abstract

A multi-sensory experience is provided to a user of a device that has a touch screen through an arrangement in which audio, visual, and tactile feedback is utilized to create a sensation that the user is interacting with a physically-embodied, three-dimensional (“3-D”) object. Motion having a particular magnitude, duration, or direction is imparted to the touch screen so that the user may locate objects displayed on the touch screen by feel. In an illustrative example, when combined with sound and visual effects such as animation, the tactile feedback creates a perception that a button on the touch screen moves when it is pressed by the user like a real, physically-embodied button. The button changes its appearance, an audible “click” is played by the device, and the touch screen provides a tactile feedback force against the user'"'"'s finger.

Claims

1. A method for providing a multi-sensory experience to a user of a device, the device including a touch screen, the method comprising the steps of:

imparting motion to the touch screen, the motion being arranged for i) confirming a user action performed on the touch screen through tactile feedback to the user, ii) simulating interaction with an object as though the object has three dimensions, and iii) being imparted responsively to the user'"'"'s touch to a representation of the object on the touch screen;

playing an audio sample that is associated with the interaction with the object, the audio sample confirming the user action through auditory feedback to the user; and

rendering a visual effect to the representation that is responsive to the interaction with the object, the visual effect confirming the user interaction through visual feedback to the user.

2. The method of claim 1 in which the motion comprises multiple degrees of freedom.

3. The method of claim 2 in which the visual effect comprises displaying the object on the touch screen so that the object appears to have a depth dimension.

4. The method of claim 3 in which the displaying comprises providing the object with a drop shadow, or rendering the object with perspective, or applying one or more colors to the object.

5. The method of claim 3 in which the visual effect further comprises an application of animation to the object.

6. The method of claim 1 including a further step of varying the motion imparted to the touch screen in response to a level of pressure that the user applies to the touch screen.

7. The method of claim 6 including a further step of varying the playing or varying the rendering in response to the level of pressure that the user applies to the touch screen.

8. A device for simulating 3-D interaction with an object displayed on a touch screen by providing a sensory feedback experience, comprising:

a touch screen arranged for receiving input indicative of a user action via touch and for displaying visual effects responsively to the user action;

one or more motion actuators arranged for imparting motion to the touch screen, the motion being arranged for i) confirming a user action performed on the touch screen through tactile feedback to the user, ii) simulating interaction with the object as though the object has three dimensions, and iii) being imparted responsively to the user'"'"'s touch to a representation of the object on the touch screen;

a sound rendering device for playing an audio sample that is associated with the interaction with the object, the sound confirming the user action through auditory feedback to the user;

a memory for storing sensory feedback logic instructions; and

at least one processor coupled to the memory for executing the sensory feedback logic instructions, the sensory feedback logic instructions, when executed, implementing the sensory feedback experience for the user responsively to the user action, the sensory feedback experience including the tactile feedback, the auditory feedback, and the visual effects.

9. The device of claim 8 further including one or more structures for implementing functionality attendant to one of a mobile phone, personal digital assistant, smart phone, portable game device, ultra-mobile PC, personal media player, POS terminal, self-service kiosk, vehicle entertainment system, vehicle navigation system, vehicle subsystem controller, vehicle HVAC controller, medical instrument controller, industrial equipment controller, or ATM.

10. The device of claim 8 in which the one or more motion actuators are arranged to move the touch screen with multiple degrees of freedom of motion so that a distinctive motion which is associated with a specific 3-D simulation may be imparted to the touch screen.

11. The device of claim 10 in which the 3-D simulation is selected from one of geometry or texture.

12. The device of claim 10 in which the one or more motion actuators comprise vibration units which include a motor and rotating eccentric weight.

13. The device of claim 12 in which the motor is arranged to be driven at variable speed, or for variable duration, or in forward and reverse directions so that a plurality of different motions may be imparted to the touch screen each of the plurality of different motions being usable to simulate a different interaction.

14. The device of claim 10 in which the one or more motion actuators comprise electro-magnets that are configurable to produce a variable magnetic field or comprise electro-static generators that are configurable to produce an electro-static discharge.

15. The device of claim 10 in which the sound rendering device includes either an integrated speaker or an externally couplable headset.

16. A computer-readable medium containing instructions which, when executed by one or more processors disposed in an electronic device, implements an architecture for simulating an interactive 3-D environment for an object displayed on a touch screen associated with the device, the architecture comprising:

a sensory feedback logic component configured for implementing a sensory feedback experience to a user of the device comprising visual feedback, auditory feedback and tactile feedback in response to an input event to a touch screen;

a touch screen controller configured for receiving the input event from the touch screen and controlling rendering of a representation of the object onto the touch screen;

an audio controller configured for controlling playback of an audio sample to confirm the input event through the auditory feedback; and

a motion controller configured for controlling force applied by one or more motion actuators to the touch screen, the force comprising variable direction, duration, and magnitude to provide distinctive motion to the touch screen for each of a plurality of different input events.

17. The computer-readable medium of claim 16 further including a host application configured for generating the interactive 3-D environment.

18. The computer-readable medium of claim 17 further including a hardware abstraction layer comprising a touch screen, audio generator, and one or more motion actuators.

19. The computer-readable medium of claim 18 in which the input event comprises a touch by the user to locate the object displayed on the touch screen by feel.

20. The computer-readable medium of claim 19 in which the input event comprises a touch by the user to interact with the object displayed on the touch screen by feel.
