Using the ELMM
Wear the ELMM on the wrist of your dominant hand. To count bites during eating, press
the on/off button at the beginning and end of a meal or snack. The device counts steps
all day without the need to press any buttons. At any time, use the review button to see
your current daily totals. Connect the device to a computer to sync your data for long-term
viewing. Recharge the device periodically. With normal use the device will last 3 weeks
between recharges. A full recharge takes approximately 45 minutes.
The top button of the ELMM turns bite counting on and off. It should only be enabled
during eating activities such as meals and snacks. During bite counting, the ELMM shows
a real-time count of total bites consumed during the eating activity. The bottom button of
the ELMM scrolls through several displays. Figure 1 shows three of them: time, total bites
accumulated for the day, and total steps taken for the day. Displays not shown include bite
count goal, step count goal, and current battery charge.

Software
Figure 2 shows the ELMM software interface. The first panel shows the display when the
software is waiting for a device to be plugged into a USB port. As soon as the device is
connected, the software automatically connects to it, syncs the time, and stores the data for
long-term viewing. Pressing the
View data at server
button will spawn your web browser
and allow you to scroll through your history of logging bites and steps.
Pressing the
Device settings
button will bring up the interface shown in Figure 3.
Daily goals for bite count and step count can be custom set. An audible alarm can be
triggered to go off during an eating activity if a daily or session count is surpassed. The
alarm goes off for each bite consumed past the specified count. Finally, the review panel
allows for customizing which displays are shown during toggling of the bottom button of the
ELMM. Note that by default bite and step goal displays are disabled.
