Abstract

Methods and a support object are provided to facilitate the receipt of a wide variety of touch inputs from a user, such as in a manner that is comfortable and does not fatigue the user. In the context of a method, touch input is received from a user who engages and moves a support object relative to a touch sensitive surface. The method also includes receiving the touch input from the user via the touch sensitive surface. The method further includes determining a relative position of the touch input with respect to the support object and then determining a type of touch input based upon the relative position of the touch input with respect to the support object. The method also includes causing an action to be taken in response to the type of touch input. Corresponding apparatus and computer program products are also provided.

Claims

1. A method of receiving touch input from a user who engages and moves a support object relative to a touch sensitive surface, wherein the support object is independently movable relative to the touch sensitive surface, and wherein the method comprises:

determining an orientation of the support object upon the touch sensitive surface while the support object overlies a portion of the touch sensitive surface, wherein the support object includes an asymmetrical pattern of contact elements that are in contact with the touch sensitive surface, and wherein determining the orientation of the support object comprises determining a location of a forward end of the support object relative to a rearward end of the support object based upon the asymmetrical pattern of the contact elements;

while the support object is in contact with the touch sensitive surface and while the user has placed a hand upon the support object such that at least one finger of the hand extends beyond the forward end of the support object and contacts the touch sensitive surface and such that a wrist and forearm of the user extend from the rearward end of the support object, receiving the touch input from the at least one finger of the user as a result of contact between the at least one finger with the touch sensitive surface at a positon upon the touch sensitive surface that is outside of the portion of the touch sensitive surface that the support object overlies so as to be located beyond an edge of the support object and to be distinct and spaced apart from the contact elements of the support object;

after having determined the orientation of the support object upon the touch sensitive surface, determining a relative position of the touch input with respect to the support object based upon the orientation of the support object upon the touch sensitive surface;

determining, with processing circuitry, a type of touch input based upon the relative position of the touch input with respect to the support object; and

causing an action to be taken in response to the type of touch input.

2. A method according to claim 1 wherein receiving the touch input comprises receiving an initial touch input followed by movement of the touch input over the touch sensitive surface as a result of corresponding movement of the support object.

3. A method according to claim 1 wherein receiving the touch input comprises receiving the touch input comprised of touch input components concurrently provided by two or more fingers of the user upon the touch sensitive surface.

5. A computer program product comprising a non-transitory computer readable storage medium having program code portions stored thereon, the program code portions configured, upon execution by the processing circuitry, to cause the method of claim 1 to be performed.

4. An apparatus for receiving touch input from a user who engages and moves a support object relative to a touch sensitive surface, wherein the support object is independently movable relative to the touch sensitive surface, and wherein the apparatus comprises processing circuitry configured to:

determine an orientation of the support object upon the touch sensitive surface while the support object overlies a portion of the touch sensitive surface, wherein the support object includes an asymmetrical pattern of contact elements that are in contact with the touch sensitive surface, and wherein the orientation of the support object is determined by determining a location of a forward end of the support object relative to a rearward end of the support object based upon the asymmetrical pattern of the contact elements;

while the support object is in contact with the touch sensitive surface and while the user has placed a hand upon the support object such that at least one finger of the hand extends beyond the forward end of the support object and contacts the touch sensitive surface and such that a wrist and forearm of the user extend from the rearward end of the support object, receive the touch input from the at least one finger of the user as a result of contact between the at least one finger with the touch sensitive surface at a positon upon the touch sensitive surface that is outside of the portion of the touch sensitive surface that the support object overlies so as to be located beyond an edge of the support object and to be distinct and spaced apart from the contact elements of the support object;

after having determined the orientation of the support object upon the touch sensitive surface, determine a relative position of the touch input with respect to the support object based upon the orientation of the support object upon the touch sensitive surface;

determine a type of touch input based upon the relative position of the touch input with respect to the support object; and

cause an action to be taken in response to the type of touch input.

13. An apparatus according to claim 4 wherein the processing circuitry is configured to receive the touch input by receiving an initial touch input followed by movement of the touch input over the touch sensitive surface as a result of corresponding movement of the support object.

14. An apparatus according to claim 4 wherein the processing circuitry is configured to receive the touch input by receiving the touch input comprised of touch input components concurrently provided by two or more fingers of the user upon the touch sensitive surface.

6. A method of identifying a type of support object upon a touch sensitive surface, wherein the support object is independently movable relative to the touch sensitive surface, and wherein the method comprises:

receiving input from a plurality of contact points of the support object via the touch sensitive surface;

determining relative positions of the contact points of the support object in order to define a signature of the support object, wherein the support object is one of a plurality of types of support objects with each type of support object having differently positioned contact points that define a different signature;

identifying, with processing circuitry, the type of support object based upon the signature of the support object;

receiving input from a finger of the user as a result of contact between the finger with the touch sensitive surface while the user has placed a hand including the finger upon the support object, wherein the input from the finger is distinct and spaced apart from the contact points of the support object; and

causing an action to be taken in response to the input, wherein the action to be taken is dependent upon both the input that is received and the type of support object that is identified such that different types of support objects as identified based upon the respective signatures cause different sets of functions to be performed in response to receipt of a same input from the finger of the user.

7. A method according to claim 6 further comprising:

determining a type of touch input based upon the relative position of the touch input with respect to the support object.

8. A method according to claim 7 further comprising determining an orientation of the support object based upon the relative positions of the contact points.

9. A method according to claim 8 wherein determining the type of touch input comprises determining the type of touch input based upon the relative position of the touch input with respect to the support object and its orientation.

10. A method according to claim 6 further comprising:

receiving touch input via a touch surface carried by the support object; and

causing an action to be taken in response to the touch input.

11. An apparatus comprising the processing circuitry configured to perform the method of claim 6.

12. A computer program product comprising a non-transitory computer readable storage medium having program code portions stored thereon, the program code portions configured, upon execution by the processing circuitry, to cause the method of claim 6 to be performed.
