Lunettes_intelligentes_Microsoft_Malvoyants_Cecite_Deficients_visuels

Travaillant chez Microsoft, Saqib Shaikh, un ingénieur atteint de handicap visuel a eu l’initiative de développer des lunettes susceptibles de décrire en détail les personnes et objets se trouvant devant les déficients visuels.

Concrètement, dès que l’utilisateur appuie discrètement sur la branche, les lunettes photographient ce qu’il regarde précisément et décrivent instantanément, via une oreillette, ce qui se trouve sur le cliché, sachant que la description peut concerner les objets, leurs formes, leurs couleurs de même que les personnes, leurs habits, leurs actions, leurs expressions faciales, etc. Ainsi, le malvoyant pourra mieux se situer dans son environnement et interagir plus facilement avec autrui.

Bien que leur apparence soit proche de celle d’une paire de solaires classique, ces lunettes connectées baptisées Pivothead intègrent plusieurs algorithmes permettant la description visuelle, la lecture de textes, de menus… ainsi que la reconnaissance des objets, du genre des personnes, de leur tranche d’âge, de leur expression faciale, de l’activité pratiquée par celles-ci, etc.

Notons que Saqib Shaikh a précisé que son travail était le fruit des années de recherche des scientifiques de Microsoft Research.

  2. Your purpose for doing the train should information the variety of reps you do
    within the cable shut grip row. The continuous pressure supplied by the cable setup maximizes muscle growth, whereas the versatility of grip
    attachments lets you target totally different muscle groups.
    Guys, the Seated Cable Row ought to completely be a half of your upper physique workouts, but provided that you’re doing it right.

    Incorporate completely different grip attachments, emphasize scapular retraction, and keep a full range of motion to boost muscle progress and overall energy.
    Incorporate Cable Row options like 1-Arm Cable Rows or Rope Cable Row variations to focus on stabilizer muscular tissues
    and secondary muscle teams. This not only reduces the effectiveness of
    the train but also puts unnecessary pressure in your higher back muscle tissue and
    might lead to a nagging harm.
    In this guide, we’ll break down all features of the cable row so that you can get
    essentially the most out of it. Cable rows activate the infraspinatus, which is another key muscle that makes up the rotator cuff.
    Alongside with externally rotating the shoulder,
    it also stabilizes the shoulder joint. For other straightforward to study cable workout
    routines, take a look at our analysis of the simplest cable back exercises.
    Expect expert-backed workouts, vitamin recommendation, the most recent
    in strength sports, and a complete lot of motivation heading your method.
    This content material is for informational and academic functions only and does not constitute
    individualized advice.
    The brachialis and brachioradialis in your arms should work onerous and the pectoralis
    main and sternal head (lower chest muscles) are additionally targeted.
    Observe that it is at the finish of the flexion portion of the motion (when the shoulder blades
    come together) that the trapezius and rhomboids really are
    available to play. Utilizing weights requires extra awareness about correct kind, said Bill
    Kelley, DPT, CSCS. The biggest problem tends to be keeping the elbows too low,
    versus letting them flare upwards on either side of the pinnacle.

    When done accurately, they target both the pectoralis main and minor, as well as the anterior deltoids.
    The suspension system permits you to use your individual physique weight as resistance, which makes it appropriate
    for all health levels. Return it downwards slowly, followed by the other arm alternating between them per repetition until the specified number of reps or units have been accomplished.
    Decrease the burden again down slowly earlier than repeating for desired reps or units.
    Now let’s look at some variations of the TRX Row to additional customise your workout routine.

    By understanding the anatomy of this train, you’ll be able to
    create a more practical workout tailor-made to your needs.

    As Soon As you’ve gotten all the means in which down,
    give your lats a squeeze while maintaining an upright posture.
    The seated cable row is a full-body movement, additionally relying on glute
    and core activation so as to keep stability and an upright
    posture. Of course, in relation to these secondarily engaged muscle
    teams, you’re going to need to make an effort to activate them to their fullest
    potential. You can completely coast through this train with out activating your glutes, but your kind (and gains) will suffer
    over the long term. Not Like many other compound back workout routines, such as the barbell row
    and deadlift, the seated cable row doesn’t place a lot load on your
    spine when performed correctly. The bulk of the muscle work gets carried out
    whenever you pull back on the shoulders.
    The seated cable row, as talked about within the introduction, is carried out
    on a cable pulley machine. However, it can be carried
    out by sitting on the bottom or by organising a bench in the cable matrix if yours doesn’t.
    Initiate the motion by reaching down to pick up the dumbbell off the ground with the alternative hand whereas maintaining your back straight and
    aligned. Interact your back and shoulders, lifting
    the dumbbell up to your chest. Once you reach the top of the train, squeeze your shoulder back and make positive you feel the engagement in your back muscle tissue.
    This isn’t based mostly on any sound scientific reasoning, though, and is actually simply fitness center lore.

    Thus, all horizontal again exercises, together with the seated cable
    row, make your back thicker, wider, and stronger. Maintaining your
    arms braced, you want to really feel rigidity always
    and transfer by way of the total vary of motion with every rep.
    They assist to maneuver these elements of the body as nicely as the arms and torso.
    Do Not crash the weights, and do not pause or bounce on the
    bottom of the carry.
    Start seated in entrance of a cable machine with
    knees barely bent so that they don’t lock out during motion (this will help defend in opposition to
    injury). Lat pulldowns are a great various to rowing exercises for working the same
    muscles. This train targets the latissimus dorsi, or lats, as properly as the
    biceps and rear deltoids. To carry out this train correctly, sit
    on a bench along with your ft flat on the ground and hold onto a bar hooked up to a cable machine above you.

    Other ways to avoid injury are to maintain your knees barely
    bent throughout while keeping your back neutrally aligned.

    Doing the exercise slowly and with intent will garner far more positive aspects in the long run than chasing
    rep counts and weight numbers. In phrases of quantity, stick to 8 to
    12 reps of two to three sets initially.
    Cable rows can be utilized to construct energy and
    measurement in your back muscular tissues in addition to improve posture.
    Lastly, there are several smaller stabilizing muscles which also get
    worked throughout cable rows. Posterior deltoids, which assist us with extending our arms outwards from our
    our bodies.
    It build strengths that interprets into a great deal of different
    workouts, corresponding to pullups and deadlifts.

    Constructing power through our again muscles helps us keep
    correct posture and defend the backbone. To effectively target and strengthen the
    erector spinae, incorporating a wide selection of workout routines is essential.
    Using a cable machine with completely different cable attachments, such
    as a V-grip bar or rope cable row equipment, ensures continuous
    tension for maximum muscle activation. The main rhomboid muscle
    keeps your shoulder blade attached to your ribcage and is responsible for helping you rotate your shoulder.
    Since seated row correct form requires maintaining your shoulders down and again,
    it engages and strengthens the rhomboids,
    defending your shoulder’s range of motion. The proper kind for
    a seated row on a machine includes sitting upright on the machine, knees slightly bent
    without curling your lower again.
    However, they can additionally indirectly work the biceps by providing
    stability to your arms throughout each rep. To carry out this exercise, stand facing away
    from the cable machine with one foot ahead and one foot behind you in a staggered stance position. Grasping
    just one handle of the cable machine, bend over slightly on the waist in order that your torso is parallel with the ground (or as shut as possible).
    Pulling simply from that arm, deliver it up in the path of your
    chest whereas preserving elbow close to physique throughout
    motion. Slowly lower arm again down until shoulder joint has returned fully extended before repeating for desired variety of reps on all sides.
    Begin by positioning your self underneath whatever surface
    you’re utilizing so that it’s roughly waist peak off floor
    (or higher if needed).
    The full vary of motion must be adhered too with each rep.
    If you restrict the range of motion, then you will restrict your features.
    « Where people tend to falter with upright rows is primarily in kind »,
    Snyder mentioned. If you create a large angle with your torso relative to your
    thighs, you’re working less mid-back and have transferred the work into your glutes and low back such
    as you would in a deadlift. End the motion together with your torso
    at 90 levels relative to the ground. Right Here, Samuel talks us by way
    of every thing there may be to know in regards to the
    cable row. So, whereas it is not solely a shoulder
    exercise, the Seated Cable Row successfully contributes to stronger, more stable shoulders.

    Do Not be afraid to make the most of the beginner format for a variety of months,
    « particularly in case you have a desk job, » Samuel says.

    « You Are saddled with years of poor shoulder blade movement, so being deliberate with how you progress may help you build the critical muscle that may serve you later. » Keep your core embraced,
    and posture upright always in the course of the motion. While leaning barely
    ahead and backward, you still need to keep your again straight.

    You can lean slightly forward in the beginning position, and slightly again ultimately position.
    You should hold your elbows away out of your sides – most
    rowing workouts are done with the arms near the sides.
    Nevertheless, dumbbell rear delt rows should be accomplished with the arms up and
    perpendicular to the physique, or they won’t be as efficient.
    Nevertheless, utilizing an extreme quantity of weight
    might mean you find yourself doing lat rows as an alternative of
    rear delt rows.
    This just isn’t necessarily higher, but some people choose cable workouts over freeweights for this reason. The good news is you could replicate the impact
    of reverse grip rows with a cable machine. Unlike being on a rowing machine or in a boat—which entails having arms straight out in front and pulling in in the path
    of your chest—upright rows are accomplished in a vertical motion. Both seated rows and bent-over rows
    may be valuable additions to your workout routine when carried out correctly.
    Think About incorporating both workouts into your training program to
    learn from their distinctive benefits and to maintain your workouts varied and
    effective. As with any exercise, prioritize
    safety and correct kind to minimize the risk of damage and maximize your results.
    Similar to traditional seated rows, you’ll pause and maintain when the bar is at the high position near your torso.

    Guarantee that the core is straight, stable
    and stuck in house at all times. It will help with virtually each exercise that exists and the Cable Row will both check and develop it.
    Variations just like the Single-Arm Cable Row and Standing Rope Cable Row supply alternative to Cable
    Rows that prevent muscle imbalances and add core stabilization. Keep In Mind to begin the motion by bending
    those wrists back and bracing your scapula. By avoiding these
    frequent errors, you can make certain that your Seated
    Cable Row technique is strong, maximizing the benefits of this
    wonderful cable exercise. Leaning too far ahead or backward can throw off your kind and scale back the effectivity of the motion.
    If you have ever seen it known as a Hammer Power high row and wondered
    why here’s why. Hammer Power is doubtless one of the premier strength and conditioning companies that produce glorious gear for machine exercises.
    They are particularly well-known for his or her row
    machines as they have a large selection, including the excessive row.
    Yes, the exercise is a protected approach to build strength and muscle in the back
    and arms. The t-bar row is sort of a extra stable model of the barbell row, however it nonetheless requires more core exercise and
    static work for your legs than the cable row variants.
    The rear delts work as stabilizer muscular tissues, guaranteeing correct scapular retraction and enhancing shoulder
    health. Whereas the Seated Cable Row primarily targets your again muscle tissue, it additionally engages your
    shoulders to some extent, particularly the posterior deltoids.

    Again, you won’t use heavy loads, so this machine excessive row substitute works best as a
    muscle hypertrophy movement. The machine excessive row is
    going to train the same set of muscular tissues that other again rows
    prepare, making it a fantastic T-bar row various.
    The main difference is within the motion pattern, which can have an effect on the p.c
    of muscle activation in the muscular tissues. These are the primary machine excessive
    row muscle tissue labored and their perform through the
    movement. Our last row replaces weights with a
    resistance band but isn’t any much less effective at putting pressure on the upper back.

    Related to the attachment you choose, how excessive you set the cable may also decide which muscles you activate.
    I chose this feature because the narrower grip offers optimum lat activation during the exercise,
    which is what I needed specifically for my personal goals.
    However, additionally they work other muscles, corresponding to the center trapezius, rhomboids, and rotator cuff muscles.
    This exercise offers people with shoulder points with an train to profit from rows.
    You can even add resistance by carrying a weighted vest,
    which will increase the amount of weight you have to carry
    with every rep. Each arm ought to be labored separately by
    completing 10 reps per aspect, or alternating arms every
    5 reps if desired. You have to focus on squeezing your lats
    collectively every single repetition quite than just relying solely upon momentum.
