Abstract
Abstract Conflicting requests for cursor control of displaying are resolved by priority. The cursors can reflect attributes of their control or those of their control units, with visual attributes being color, shape or the like. Priority may be established between each cursor and a range of areas acceptable for cursor movement subdivided from the screen, or according to a priority of allowable functions, or according to a priority of conflicting operating times, or a combination of the same. Simultaneous control of a plurality of cursors can be permitted when there is no conflict.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
93 words
An apparatus for screen display of information, comprising: means for displaying a plurality of cursors indicating access to information; a plurality of input units for respectively operating said cursors; means establishing access levels of the cursors; means for establishing access acceptance levels corresponding to information on the display; means for comparing an access acceptance level of information indicated by a cursor with an access level of the indicating cursor; and means for controlling screen display based upon an access signal from one of the input units that falls within said access acceptance level.
Claim 2
Independent Claim
93 words
An apparatus for screen display of information, comprising: means for displaying a plurality of cursors indicating access to information; a plurality of input units for respectively operating said cursors; means establishing access levels of the cursors; means for establishing access acceptance levels corresponding to information on the display; means for comparing an access acceptance level of information indicated by a cursor with an access level of the indicating cursor; and means for controlling screen display based upon an access signal from one of the input units that falls within said access acceptance level.
Claim 3
Dependent Claim
24 words
The apparatus of claim 1, including means providing each of said cursors with visual attributes uniquely corresponding with the access level of each cursor.
Claim 4
Dependent Claim
13 words
The apparatus of claim 2, wherein said visual attributes are different cursor shapes.
Claim 5
Dependent Claim
13 words
The apparatus of claim 2, wherein said visual attributes are different cursor colors.
Claim 6
Dependent Claim
15 words
The apparatus of claim 1, wherein said access acceptance levels correspond to different subscreen areas.
Claim 7
Independent Claim
81 words
An apparatus for screen displaying, comprising: screen means displaying a plurality of cursors each being defined by a respective cursor ID and information; plural input means for accessing the information through operating the cursors; means for defining respective access levels of the cursors; means for defining an access acceptance level of the information; and means for permitting a particular cursor to access particular information when the access level of the particular cursor satisfies the access acceptance level of the particular information.
Claim 8
Independent Claim
81 words
An apparatus for screen displaying, comprising: screen means displaying a plurality of cursors each being defined by a respective cursor ID and information; plural input means for accessing the information through operating the cursors; means for defining respective access levels of the cursors; means for defining an access acceptance level of the information; and means for permitting a particular cursor to access particular information when the access level of the particular cursor satisfies the access acceptance level of the particular information.
Claim 9
Dependent Claim
38 words
An apparatus according to claim 6, wherein said means for permitting permits the particular cursor having a highest access level to access the particular information when a plurality of the cursors try to access the same particular information.
Claim 10
Independent Claim
131 words
A method for screen displaying, comprising the steps of: displaying plural cursors each being defined by a respective cursor ID on a screen of an apparatus for screen displaying; operating the cursors by plural input means, each being defined by an input means ID; defining respective access levels of the plural input means by using the input means ID; defining respective access acceptance levels of the cursors by using the cursor ID; and supervising the cursors and the plural input means based on the cursor ID and the input means ID to exclude the possibility that each cursor is operated by plural input means at the same time and so that a particular input means, whose access level satisfies the access acceptance level of a particular cursor, operates the particular cursor.
Claim 11
Independent Claim
131 words
A method for screen displaying, comprising the steps of: displaying plural cursors each being defined by a respective cursor ID on a screen of an apparatus for screen displaying; operating the cursors by plural input means, each being defined by an input means ID; defining respective access levels of the plural input means by using the input means ID; defining respective access acceptance levels of the cursors by using the cursor ID; and supervising the cursors and the plural input means based on the cursor ID and the input means ID to exclude the possibility that each cursor is operated by plural input means at the same time and so that a particular input means, whose access level satisfies the access acceptance level of a particular cursor, operates the particular cursor.
Claim 12
Independent Claim
103 words
A method for screen displaying, comprising: displaying plural cursors, each being defined by a respective cursor ID and a type of information to which plural input means may give access through operating the cursors; defining a respective access level for each of the cursors; defining a respective access acceptance level for each of the types of information; comparing an access acceptance level of information requested by a cursor to an access level of the cursor; and operating a particular cursor to give access to particular information when the access level of the particular cursor satisfies the access acceptance level of the particular information.
Claim 13
Independent Claim
103 words
A method for screen displaying, comprising: displaying plural cursors, each being defined by a respective cursor ID and a type of information to which plural input means may give access through operating the cursors; defining a respective access level for each of the cursors; defining a respective access acceptance level for each of the types of information; comparing an access acceptance level of information requested by a cursor to an access level of the cursor; and operating a particular cursor to give access to particular information when the access level of the particular cursor satisfies the access acceptance level of the particular information.
Claim 14
Dependent Claim
41 words
A method for screen displaying according to claim 9, wherein said operating step permits only a particular cursor having a highest access level to obtain access to the information when a plurality of the cursors try to access the same information.
