• Fig. 1 is a simplified block diagram of a MCT 10 that incorporates at least one accelerometer 28 in accordance with an aspect of this invention.
• the MCT 10 contains a data processor such as a microprocessor control unit (MCU) 12 that coupled to a visual display 14, such as an LCD, and that receives input from a keypad 16.
• the keypad 16 is assumed to include at least one Select Key (SK) , as will be described in greater detail below.
• Other keys can include alphanumeric keys, soft keys, a power on/off key, etc., as is conventional in these types of devices .
• the combination of the MCU 12, display 14 and keypad 16 provides the user interface (UI) of the MCT 10.
• a memory (MEM) 12A stores an operating program for the MCU 12, as well as user entered and other data and constants.
• the memory 12A may store Phonebook data representing a plurality of names and telephone numbers that were previously entered by the user.
• the MCT 10 may also include a digital signal processor (DSP) type of device 18 that implements the required baseband and audio functions.
• DSP digital signal processor
• a radio frequency (RF) transceiver 20 is bidirectionally coupled to the DSP 18, as well as to at least one antenna 22. Using the transceiver 20 and antenna 22 the MCT 10 is enabled to establish bidirectional communication links with remote transceivers, and to gain access to voice and data communication networks.
• a speaker 24 (or earphone) and a microphone 26 are typically also coupled to the DSP 18 for enabling a user to make and receive telephone voice calls.
• the MCT 10 also includes at least one accelerometer (ACC) 28 having a sensitive axis (SA1) about which the accelerometer is capable of sensing accelerations. In the preferred implementation these accelerations are due to the force of gravity.
• a second accelerometer 30 may also be provided so as to have its sensitive axis (SA2) aligned differently (e.g., orthogonally) to the sensitive axis (SA1) of the first accelerometer 28. In this manner the MCT 10 is capable of sensing accelerations about each sensitive axis.
• Fig. 2 is a top view of the MCT 10, and shows an exemplary orientation of both of the sensitive axes, as well as the viewing directions of Figs. 3 and 4.
• Figs. 3A, 3B and 3C are a side view of the MCT 10 of Fig. 2 and depict, in Fig. 3A, the MCT 10 aligned along a first neutral plane (NP1) , rotated in a positive direction about the first sensitive axis out of the first neutral plane
• NP1 first neutral plane
• Fig. 4 is an end view of the MCT 10 and depicts the
• MCT 10 rotated in a positive direction about the second sensitive axis out of a second neutral plane (NP2) .
• the first neutral plane NP1 is defined such that the first accelerometer 28 does not experience an acceleration due to gravity, and thus ideally provides either no output to the MCU 12 or an output indicating zero acceleration.
• the first neutral plane (and hence the orientation of the first accelerometer within the case of the MCT 10) is such that the MCT 10 is positioned in some convenient orientation relative to the local normal.
• the first neutral plane may be oriented at 45 degrees to the local normal (LN) .
• the accelerometer 28 detects the acceleration due to force of gravity and generates an output.
• the magnitude of this rotation indicated by the angle (A) in Figs. 3B and 3C, generates a proportionate increase or decrease in the output signal of the accelerometer 28, while the direction of the rotation can be indicated in the sign of the output signal.
• the output of the accelerometer 28 may have some value X, and subsequent rotations in to or out of the neutral plane can cause a corresponding increase or decrease in the value of X.
• the MCU 12 of Fig. 1 interprets the output of the accelerometer 28 (and accelerometer 30 if provided) as an input user interface signal and employs same to control the direction of the scrolling of information on the display 14.
• the speed of the scrolling is controlled as well.
• This scrolling can be used to display in succession the names of various applications such as: "Phonebook”, followed by "Messages”, followed by “Settings”, followed by "Security Options", etc.
• the scrolling speed may be caused to increase in a proportionate manner.
• the MCU 12 interprets this signal so as to terminate the scrolling operation, regardless of the current orientation the MCT 10. That is, the output signal of the accelerometer 28 can be simply ignored, or the accelerometer 28 may be de-energized to save power. If the Select Key is released, then the scrolling operation can be restarted.
• the scrolling feature may be again used to scroll through the stored list of names and telephone numbers until a desired entry is found.
• a desired application e.g., Phonebook
• Depressing the Select Key again can then interpreted as a signal that indicates that the currently displayed Phonebook entry is to be selected, such as by automatically originating a call to the telephone number stored for the currently displayed Phonebook entry.
• the teachings of this invention can be used to scroll both to and then through a desired MCT 10 application.
• the use of this invention can be used when scrolling through other types of displayed information.
• the MCT 10 has been used to log on to a global data communications network, such as the Internet.
• the use of the accelerometer 28 can then be employed by the user to scroll through displayed World Wide Web (WWW) pages, to stop at a desired page, and to then scroll through the displayed desired page.
• WWW World Wide Web
• the second (optional) accelerometer 30 may be employed in a different manner for moving an indicator, such as a cursor 14A (see Fig. 2) , in a left to right or right to left fashion across a row of displayed alphanumeric characters (e.g., "AaBaCaDa ... " ) .
• the orientation shown in Fig. 4 may be one where the cursor 14A moves in a left to right fashion at a speed that is a function of the magnitude of the angle B.
• the cursor 14A may wrap to the next row.
• depressing the Select Key may be interpreted as a signal to select the indicated character, thereby entering the character into an underlying application
• the output of the first accelerometer 28 may be employed to move the cursor 14A from row to row. In this manner a simple manipulation of the MCT 10 in three dimensional space is sufficient to navigate the cursor 14A around the display 14.
• the Select Key need not be a separate and dedicated keypad key, but could be an already existing key (e.g., a soft key) whose function is redefined when operating the accelerometer 28 (and/or 30) .
• the teachings of this invention enable a simplified and uncluttered user interface to be provided, wherein a required number of scrolling arrow keys and the like can be reduced or eliminated. It should be further realized that the MCT 10 may also include conventional keypad keys and functionality for scrolling through displayed information and for entering information in a conventional manner, for use during those times when the user may not desire to use the accelerometer 28 (and/or 30) .
• the angle of the first neutral plane (NP1) with respect to the local normal (LN) need not be fixed. That is, it is within the scope of these teachings to provide a MCT 10 calibration application and procedure whereby, and by example, the user selects and enters the calibration application, orients the MCT 10 at some desired angle about the first sensitive axis SA1 (or the second sensitive axis SA2) , and then depresses SK or some other key to signal the MCU 12.
• the MCU 12 reads the current output of the associated accelerometer 28 or 30, and then stores this value in the memory 12A as a "zero" value that is indicative of the angular relationship between the desired neutral plane and the local normal. Subsequent rotations of the MCT 10 are then referenced to this zero value.
• the teachings of this invention are not limited to only the use of accelerometers. In general, any device or devices that are capable of detecting a motion or a rotation of the MCT 10 relative to some reference axis or plane may be employed.
• the MCU 12 may be used to de-energize one or both of the accelerometers 28 and 30 when their use is not required, thereby reducing power consumption. For example, when scrolling through an application or a data file using the accelerometer 28, the accelerometer 30 may be de- energized or otherwise placed in a reduced power consumption state. If an application is then selected that requires character input, the accelerometer 28 can be de- energized, or otherwise placed in a reduced power consumption state, and the accelerometer 30 energized.
