Description

BACKGROUND

Handheld computing devices such as personal digital assistants or handheld computers generally provide some combination of personal information management, database functions, word processing and spreadsheets, as well as communications network connectivity, internet connectivity, voice memo recording, and telephony functions. Further, handheld computing devices may include local area wireless technology permitting communication with other computing devices within a local area.[0001]

Handheld computing devices that include local area wireless capabilities may communicate with other computing devices using protocols or standards such as but not limited to Bluetooth wireless technology, IEEE 802.11 architecture, or other relevant technologies or standards. Local area wireless communications are typically between devices located proximate one another, such as within twenty meters. The communication signals sent between the computing devices are typically radio frequency (RF) signals but may also include infrared or ultrasonic signals.[0002]

While handheld computing devices that include local area wireless communication capability may communicate with each other, they may also communicate with computing devices connected to land lines, such as a wired local area network access point, or other hardwired computing devices. Further, the wireless handheld computing devices may share information with other types of wireless electronic devices such as cellular phones or laptop computers.[0003]

Local area wireless communication capability permits computing devices to communicate and share information such as files with one another without the use of a wired or cellular network. Sharing information may involve one or both of transmitting and receiving information. A local area wireless connection may be used to interface with a wired computer network or to browse the internet utilizing a nearby computing device that is connected to the internet. Further, documents, business cards, computer files, and even voice communications may be communicated between multiple computing devices that are linked together in a wireless local area network. Further still, local wireless connectivity permits the synchronization of various computing devices such as handheld computers, cellular phones, and laptops without the use of wired connections or more complicated wireless computing protocols such as those used by cellular phones.[0004]

In order for handheld computing devices to communicate with one another and other computing devices via local area wireless technologies, the various devices and their users of ten desire to be able to accept or decline messages that are received, and preferably target outgoing messages to particular receiving devices, rather than indiscriminately broadcasting communications to all proximate wireless computing devices.[0005]

One way for computing devices to more selectively communicate with one another is for the user to select the device or devices to which a communication should be made prior to sending the communication. The device may then send the communication such that it is received only by the chosen computing devices rather than all computing devices within range of the transmitted signal. The number of computing devices within range of a computing device with a wireless transmitter may be large given the rapidly increasing use of local area wireless technologies and the long range of RF signals as compared to the infrared signals used by earlier devices.[0006]

Permitting the user to choose the local computing devices with which information should be shared presents difficulties if the number of possible receiving devices is large. A typical method of presenting the possible choices to the user would be to list the devices on a display associated with the user's handheld computer. The user may then scroll through the list or use a stylus to tap on the desired devices to which the user wishes to transmit information. However, as the number of possible devices grow large, the action required by the user becomes more cumbersome, as it may be necessary to scroll through a long list of local area devices, and choose one or more of them. Further, it may not be immediately apparent to the user which nearby computing device corresponds to the indicator shown on the user's computer device, making the selection more difficult.[0007]

Therefore, there is a need for a handheld computing device with local area wireless technology that permits the user to more easily choose other computing devices in the local area with which the user wishes to communicate. Further, there is a need for a more logical approach to selecting a group of one or more devices to which a wireless communication should be sent without individually selecting each device from a list.[0008]

The teachings herein extend to those embodiments that fall within the scope of the appended claims, regardless of whether they accomplish one or more of the above-mentioned needs.[0009]

Referring to FIG. 4,[0028]

handheld computer

100 may be capable of communicating with other computing devices withinlocal area126. In the exemplary situation of FIG. 4,handheld computer100 may be able to communicate with various other local area computing devices such as, but not limited to computing devices having wireless communication capability such assoda machine200, first handheld computer (Paula's Handheld)202, second handheld computer (Steve's Handheld)204, laptop computer (Diane's Laptop)206, cellular phone (Chuck's Cellular Phone)208, local area network (LAN)port210, and automated teller machine (ATM)212.

Referring to FIG. 5,[0029]

handheld computer

100 may assign each of theother computing devices200 through212 a name to facilitate identification of possible communication devices by the user ofhandheld computer100. The name or indicator associated with the other local area wireless devices200-212 is descriptive in an exemplary embodiment rather than corresponding to a numerical computer address for the other devices. In the embodiment shown in FIG. 5, the device indicators include the name of the user of certain devices to facilitate identification. The list of other local area wireless devices may be placed ondisplay114 ofhandheld computer100 for possible selection by the user. As shown on FIG. 5, the list may be sorted alphabetically by device indicator. In other embodiments, the list may be randomly set forth. If the user ofhandheld computer100 wishes to communicate withsoda machine200, user may be required to scroll through a list of all local area computing devices, such as200-212 to find andselect soda machine200.

Referring to FIG. 6, in an exemplary embodiment of the present invention,[0030]

handheld computer

100 displays a list of local area wireless computing devices presented in order of distance fromhandheld computer100. Because it is likely that the user ofhandheld computer100 wishes to communicate with a device located proximatehandheld computer100, listing available devices in order of distance fromhandheld computer100 will present the most likely desired choice by user at or near the top of the list, creating a more efficient selection process. For example,soda machine200 is most proximate tohandheld computer100 and therefore is listed at the top ofdisplay114, facilitating selection by user as compared to the list shown in FIG. 5. The more efficient ordering of selection possibilities is especially important with respect to devices such ashandheld computer100 because the limited space ondisplay114 may require scrolling through several pages of possible choices with less efficient ordering methodologies.

[0031]

Handheld computer

100 may determine the distance to other localarea computing devices200 through212 in a number of ways. In an exemplary embodiment,handheld computer100 sends an electronic locator signal to other local devices and calculates the locations of the other devices utilizing the response time from the other devices. Such “electronic pinging” may be continuously done byhandheld computer100 without interaction from the user, and may elicit automatic responses from other localarea computing devices200 through212.

The listing of devices with which the user may wish to communicate may be presented on[0032]

display

114 ofhandheld computer100 or may be presented utilizing other methodologies, such as an audible communication.

Referring to FIG. 7, in another embodiment,[0033]

handheld computer

100 may present a directional listing of localarea computing devices200 through212. For example, ifhandheld computer100 is pointed directly at Steve's handheld204, the list of communications choices presented byhandheld computer100 to the user may begin with Steve's handheld204 and Diane'slaptop206 before listing the closerdevices soda machine200 and Paula's handheld202 because the list is keyed to direction fromhandheld computer100 rather than solely based on proximity.

A directional listing of local area wireless computing devices may be more useful than other list orders because it is likely that the user of[0034]

handheld computer

100 will be pointinghandheld computer100 at the device with which the user wishes to share information. The directional information used for sorting the list of proximate devices may be acquired byhandheld computer100 through the electronic pinging of other localarea computing devices200 through212.

[0035]

Handheld computer

100 may utilize both distance and direction simultaneously to sort indicators ofother computing devices200 through212. For example, a number of computing devices may be located at a similar distance, and accordinglyhandheld computer100 may sort the list based first on distance fromhandheld computer100, but secondly based on the direction fromhandheld computer100 if necessary.

The user of[0036]

handheld computer

100 may wish to choose a subset of devices with which to communicate out of the larger set of all local area wireless devices. One way of making such a selection would be to scroll through the list of all local area devices set forth ondisplay114 and choose each member of the subset of devices individually. Rather than performing such an individual selection process, in an exemplary embodiment, a distance metric may be used to select the subset of devices.

For example, user of[0037]

handheld computer

100 may wish to send a message to all local area wireless devices within a particular radius ofhandheld computer100, denoted bysub area128 on FIG. 4. If user ofhandheld computer100 wishes to share information with all local area wireless devices withinsub area128, a distance metric equal to the radius ofsub area128 maybe chosen such that communications will be effectuated betweenhandheld computer100 and

wireless devices

200,202,204,206, and208 but not to and from

wireless devices

210 and212 which are outsidesub area128. In an exemplary embodiment, the user may be permitted to choose any distance metric for communicating with a desired sub-group of wireless devices within a particular radius ofhandheld computer100.

The software used to permit the various display ordering and groupings of local[0038]

area computing devices

200 through212 may be part of an operating system, such as Palm OS, or may be a program loaded separately ontohandheld computer100. The software may be developed in any number of conventional programming languages. In other embodiments, the instructions may be carried out by hard wired circuitry or by a combination of circuitry and software.

The user interface and display methodologies described herein address the various needs of the conventional art by permitting efficient communication between local area wireless devices. By permitting a user of[0039]

handheld computer

100 to list proximate devices categorized by distance or direction, or by permitting the grouping of devices by a distance metric, the user ofhandheld computer100 may more efficiently communicate with other computing devices.
