Abstract

An operation touch pad (4) is disposed near the hand of a user. On a display (2), there is displayed one or more GUI parts (3) for the user to input a desired instruction or information. When the user touches the touch pad (4) by a hand (6) so as to select the GUI parts (3), the touch pad (4) outputs contact position data indicating the area of contact with the hand (6). An image (7) of a hand shape model is generated from the contact position data outputted from the touch pad (4) and is displayed on the display (2). In view of the image (7) displayed on the display (2), the user moves the hand (6) so that the finger tip of the model may come to over the desired GUI parts (3), and then pushes the touch pad (4).

44. The input device according to claim 41, wherein the detecting unit includes a plurality of pressure sensors arranged along the operation surface.

45. The input device according to claim 44, wherein the contact position data includes pressure values detected by the pressure sensors of the detecting unit, and

the body position displaying unit forms a contact area image corresponding to the pressure values detected by the pressure sensors of the detecting unit, based on the contact position data.

46. The input device according to claim 45, wherein colors of parts of the contact area image formed by the body position displaying unit are varied according to the pressure values detected by the pressure sensors of the detecting unit.

47. The input device according to claim 41, wherein the body position displaying unit performs a calibration processing to obtain a characteristic of the body part of the user based on the contact position data outputted from the detecting unit, and performs the modeling of the shape of the body part of the user based on a result of the calibration processing.

48. The input device according to claim 41, further comprising a non-contact type position detecting sensor near the detecting unit, wherein

the position detecting sensor detects an orientation of a hand with respect to the detecting unit, and

the body position displaying unit forms the contact area image by using the orientation of the hand.

49. The input device according to claim 48, wherein based on the orientation of the hand and a contact position of a fingertip which are outputted from the detecting unit, the body position displaying unit estimates a position of a palm to form the contact area image.

50. The input device according to claim 41, further comprising a controlling unit that determines, based on the contact position data outputted from the detecting unit, whether the body part of the user is in contact with or close to the operation surface of the detecting unit, wherein

based on the contact position data outputted from the detecting unit, the display information creating unit changes a display image to be formed, and only when the controlling unit determines that the body part of the user is in contact with or close to the operation surface of the detecting unit, the display information creating unit forms the display image.

51. The input device according to claim 41, further comprising a controlling unit that determines, based on the contact position data outputted from the detecting unit, whether the body part of the user is in contact with or close to the operation surface of the detecting unit, wherein

based on the contact position data outputted from the detecting unit, the display information creating unit changes a display image to be formed, and when the controlling unit determines that the body part of the user is in contact with or close to the operation surface of the detecting unit, the display information creating unit highlights a GUI part in the display image to be formed.

52. The input device according to claim 41, further comprising character detecting means for detecting a character of the body part of the user in contact with or close to the operation surface of the detecting unit based on the contact position data outputted from the detecting unit,

wherein the display information creating unit changes the display image to be formed, according to the characteristic of the body part of the user detected by the character detecting means.

53. The input device according to claim 52, wherein the character detecting means determines whether the body part of the user in contact with or close to the operation surface of the detecting unit is a right hand or a left hand based on the contact position data outputted from the detecting unit, and

the display information creating unit changes the display image to be formed, according to a result of the determination by the character detecting means.

54. The input device according to claim 53, wherein the display information creating unit creates display information only when the body part of the user in contact with or close to the operation surface of the detecting unit is a right hand or a left hand.

55. The input device according to claim 53, wherein the display information creating unit highlights a GUI part in the display image to be formed, change a position of the GUI part, or changes validity of the GUI part when the body part of the user in contact with or close to the operation surface of the detecting unit is a right hand or a left hand.

56. The input device according to claim 52, wherein the character detecting means determines whether the body part of the user in contact with or close to the operation surface of the detecting unit is a body part of an adult or a body part of a child based on the contact position data outputted from the detecting unit, and

the body position displaying unit changes the display image to be formed, according to a result of the determination by the character detecting means.

57. The input device according to claim 56, wherein the display information creating unit creates display information only when the body part of the user in contact with or close to the operation surface of the detecting unit is a body part of an adult or a body part of a child.
